Sellura

26 marketplaces, each dated and linked to its docs

Listing character limits for every marketplace Sellura writes for

Published title caps, shortest to longest: Mercado Libre 60 (in most categories), Shopify 70 (SEO page title), Amazon 75, Amazon Handmade 75, eBay 80, Poshmark 80, Folksy 80, Bonanza 80, Wix 80, Vinted 100, Squarespace 100 (SEO page title), Alibaba.com 128, Etsy 140, Walmart 150, Google Shopping 150, AliExpress 218, BigCommerce 250, TikTok Shop 255, Temu 500 characters. Depop and WooCommerce and Grailed and Whatnot publish no title length at all. Shopee recommends 25–100 characters and publishes no hard cap. Mercari publishes no title length, and its listing form stops at 80. Facebook Marketplace publishes no title length, and its listing form stops at 99.

Below: every listing field with a published limit on every marketplace Sellura writes for, each with the date it was last checked against the platform's own documentation and a link to that document. The caps are the platforms'. The writing targets further down are ours, and this page keeps the two apart — a target repeated as a rule is how one tool's opinion ends up quoted as Etsy policy.

Where a cell says “ours”, the number is the budget Sellura writes to, not one the platform publishes for that field. The table prints it so the row is complete; it is not a rule to quote.

Where a cell says “form, not published”, the number is where that marketplace's own listing form stops, read from the form itself on the date in the row. It is the limit the marketplace runs, but no page of its help states it, so quote it as the form's, not as a published rule.

Where a cell says “retired API only”, the number is the marketplace's own, but it is printed only in a version of its listing API that it no longer offers. The current version states no such cap. Sellura writes inside it, and this page does not quote it as a current rule.

Amazon and Amazon Handmade have a second indexed headline field beside the title — Item highlights, capped at 125 characters, indexed equally with the title and displayed only while the title stays under its own cap. No other marketplace here has one.

Our targets

What Sellura aims for, and why it is lower

These are our numbers, not the platforms'. They are what the generator writes to and what the scorer rewards. Where a platform argues for a shorter title itself, the row says so.

Why each target is lower, marketplace by marketplace
  • Etsy: Etsy publishes the 140-character cap and no recommended length. The shorter target is our reading of its 2026 guidance, which asks for a natural title under fifteen words and says nothing at all about how search treats the long keyword-chain titles it used to reward — in either direction.
  • Amazon: Amazon caps the title at 75 characters for every product type except media and gives the rest of the detail to Item highlights, 125 characters under the title. It also bans ! $ ? _ { } ^ ¬ ¦ and any word used more than twice, and puts the brand first. Aiming a little under 75 is ours: a title over the cap may be rewritten by Amazon.
  • Amazon Handmade: Amazon cut this cap from 200 to 75 on 27 July 2026 and added a second searchable field, Item highlights, of 125 characters. Aiming a little under the cap is ours: Amazon only displays the highlights field while the title stays under 75, so writing to the last character costs you the other field.
  • eBay: The 80 is enforced by eBay's own API, not merely recommended. Using most of it is our advice rather than eBay's, and it matters more here than on most platforms: eBay gives a seller no tags field, so the title and the item specifics are the only places a searched phrase can live.
  • Shopify: Both numbers are Shopify's, and neither is really a marketplace rule — they are the page-title limits of a storefront you own. Like WooCommerce, Wix, Squarespace and BigCommerce, it is a store with no marketplace search of its own behind it, so the title is written for site search and for Google rather than for a ranking algorithm somebody else operates.
  • Depop: Depop has no title field. The first line of the description does that job, and Depop publishes no character count for it — not for the description, not for the first line, not for where its app clips the text. Both numbers here are ours: roughly one phone-width line. Say that Depop publishes no length; never that Depop has no limit.
  • Walmart: Walmart publishes both, the cap in its product details policy and the 50 to 75 in its 2020 Listing Quality guide, and its 2020 item setup spec adds a shape: brand, then the defining qualities, then the item name, then the pack count if there is one. It is also one of the few platforms here that publish a list of words they reject outright.
  • Poshmark: Poshmark publishes the 80-character cap and no recommended length. What it does publish is a shape: the brand, the style name, the category, the size and the colour where they apply, and, on its blog of 13 October 2025, a warning against keyword stuffing. Using most of the 80 on those, each once, is our reading of that advice.
  • Vinted: The 100 is Vinted's, from the validation rules of its own listing API; the help centre for members prints no number. The 60 is ours: Vinted asks for the brand, the colour and the item type in the title, without words like nice or pretty, and its own example is five words.
  • Shopee: Shopee publishes no hard cap for Singapore or the Philippines: its developer guide says limits differ by market and type of seller and reach each shop through its listing API. What it publishes is a range, 25 to 100 characters, for a good product name. We write to the top of that range, so the 100 here is ours. Its naming rules are Shopee's own: each word capitalised, no promotional words, none of the symbols it lists.
  • Mercado Libre: Mercado Libre sets the title limit per category, and publishes it with each category. It is 60 in most of them, more in a few (200 for car parts and real estate, 120 for perfumes in Mexico), and never less than 60, so a 60-character title fits every category. Many sellers now type a family name and Mercado Libre builds the title from it and the attributes.
  • Mercari: Mercari's help prints no title length. The 80 is where Mercari's own listing form stops the title, read from the code of that form on 22 October 2026, so it is the limit Mercari runs but not a rule it publishes. What Mercari does publish is advice: clear, relevant keywords a buyer would actually type, the brand stated when you know it, nothing unrelated. Using most of the 80 on those, each once, is our reading of it.
  • Temu: Temu's listing API caps the product name at 500 characters, in every version and on its US, EU and global documentation, and cuts anything longer. It also allows only letters, numbers and common punctuation. Temu publishes no recommended length and no advice on how to write a name, so the 120 we aim for is ours: enough for the item, its key specs and its use, short enough to read in full.
  • Alibaba.com: Alibaba.com caps the product name at 128 characters in both of its listing APIs and in its 2026 supplier guide. It publishes no recommended length, so the 100 the checker aims for is ours: room for the item, the specs a buyer filters by and the use, without a list of keywords. Its own advice is to avoid repeating keywords, never to use only a brand or model number as the name, and to avoid + \ and quotation marks.
  • AliExpress: AliExpress's current posting API for overseas merchants takes a title of up to 218 characters (read 22 October 2026). For local goods its Rules Center recommends 79 to 128 characters and says not to overuse keywords (released 31 December 2024). In what we could read it has no rule about ALL CAPS or promotional words. Aiming at about 120 is ours, inside AliExpress's range: it keeps the item, its model and its key specs at the front.
  • TikTok Shop: TikTok Shop's listing API takes a US product name of 1 to 255 characters, and its US quality guidelines ask for at least 25 for the Good tier. TikTok publishes no recommended length, only that a good name is concise and accurate, with no clickbait, no variant lists and no word repeated more than four times. The 100 we aim for is ours: room for the item, the one or two attributes that set it apart and its use.
  • Facebook Marketplace: Meta publishes no title length for a Marketplace listing. The 99 is where Facebook's own listing form stops the title: at 100 characters it asks you to shorten it (read 24 October 2026), so it is the limit Facebook runs but not a rule it publishes. Meta's only length advice is for catalog products, under 65 characters so a title is not cut off, and the 65 we aim for borrows it: ours, not a rule for your listing.
  • Google Shopping: Both numbers are Google's: the 150 is the title's cap in the Merchant Center product data specification, and "Use all 150 characters" is Google's own advice on the title page, with the most important details first because shoppers usually see only the first 70 or fewer. A title written by AI goes in the structured_title attribute, marked as AI-generated: that is Google's rule too (read 24 October 2026).
  • Folksy: Folksy's help says titles can be up to 80 characters, and its listing form stops there and refuses a forward slash. Folksy asks for complete titles with the most important words first, and gives no shorter target, so the 75 we aim for is ours: close to the cap, with a few characters left for your own edit.
  • Bonanza: Bonanza's listing API takes a title of up to 80 characters (read 24 October 2026). Bonanza publishes no recommended length. Its Help Center's title tips (updated 16 February 2024) advise against all caps, excessive punctuation and fluff words such as "new", and say to make full use of the character limit with strong keywords. Aiming at about 75 is ours, the same as on eBay, whose categories Bonanza shares: most of the 80, with the item and the words a buyer types first.
  • WooCommerce: WooCommerce publishes no length for the product name, in its documentation or its REST API, and its product editor says the field accepts letters, numbers, special characters, emoji and even HTML. WordPress makes the name the page's title in search results, followed by the site name, and Google publishes no length for that line either. Both numbers here are ours: 70 at most and about 60, so the name and a short store name stay readable (read 25 October 2026).
  • Wix: Both numbers are Wix's: a product name takes up to 80 characters, and Wix builds the page's title tag from the product name and the site name, recommending concise names of at most 60 characters (Wix Stores help, read 25 October 2026). Wix adds the site name after the product name in that title tag, so a short name leaves the site name room to show. Like Shopify, a Wix store is your own website: the title is written for Google and for the shopper, not for a marketplace's ranking.
  • Squarespace: Both numbers are Squarespace's. A product name can run to 200 characters and an SEO title to 100, and with no SEO title set the product name is what search shows, so the checker caps at the lower one: a name of 100 or fewer fits both fields. Keeping it to 70 characters or fewer is Squarespace's own advice for titles (read 25 October 2026). By default Squarespace adds a hyphen and your site title after a product's title in search, so the site name counts against the 70.
  • Grailed: Grailed publishes no character length for the title, in its help or its How to Sell Guide. What it publishes is a word count: keep the title to 3 to 6 words, named the way the designer or retailer named the item, and leave the designer out because the designer goes in a field of its own (read 26 October 2026). Both numbers here are ours: 60 at most and about 40, which is what six words of a model name, a colour and a material come to. Extra keywords go in Grailed's tags, not the title.
  • Whatnot: Whatnot publishes no length for a listing's title, in its help or in its Seller API, where the title is a text field with no maximum (read 26 October 2026). Its advice is a clear, descriptive title, and it says descriptive titles and relevant keywords help buyers find an item in Whatnot's search. Both numbers here are ours: 80 at most, the cap eBay and Poshmark set, where resale listings are carried over from, and about 60, so the brand, the item and the key detail read in full on a phone.
  • BigCommerce: Both numbers are BigCommerce's: a product name takes up to 250 characters and must be unique in your store, and BigCommerce advises page titles of less than 60 characters that start with a relevant keyword (read 26 October 2026). With no Page Title set, BigCommerce uses the product name as the page title, and its own example of a good page title ends with the store's name, so the store name counts against the 60. Like Shopify, a BigCommerce store is your own website: the name is written for Google and for your store's search box, not for a marketplace's ranking.

Read the row, not just the number

Where the cap alone gives the wrong answer

Amazon publishes no bullet or description length for its main catalog

Amazon's bullet point requirements ask for at least three bullets and say the character limits vary by product type. The per-type numbers live in Amazon's product type definitions, which only an app a seller or vendor has authorised can read, so the five bullets of 250 characters on this page are our budget. The 500 per bullet and 1,000 in total that guides quote are Amazon Handmade's published rule.

No readable Amazon page gives a description length either: the 2,000 here is ours. The title's 75, Item highlights' 125 and the search terms' under-250 bytes are Amazon's own, read on Seller Central on 24 October 2026, and an over-limit search terms field is ignored whole, not trimmed.

The Amazon title cap moved from 200 to 75 in July 2026

Amazon cut the product title cap to 75 characters on 27 July 2026 and introduced a second field, Item Highlights, capped at 125. Both are search inputs and Amazon's own forum answer says neither is prioritised over the other.

Our registry itself carried the old 200 for five weeks after the change, with a recommended length of 80 sitting above a cap of 75 — a target larger than the limit it was meant to respect. It held because nothing checked the registry's own internal consistency; a test does now.

If a guide still prints 200, it predates the change or copied something that did.

Etsy does not publish a penalty for long titles

Etsy's handbook recommends short, readable titles. It does not say that titles written to the older keyword-stuffing advice rank worse, in either direction, and we could find no such statement in the handbook or in archived copies of it.

The widely repeated claim that Etsy penalises long legacy titles traces to eRank, a third-party tool, not to Etsy. We treat long titles with a taper because we think it is right, not because Etsy told us to.

One more trap for anyone dating the source: the revision stamp on that handbook article is a last-revised date, not a publication date.

Depop publishes no length limit at all

Depop's help centre describes how to list and how to describe an item without stating a character count for the title line anywhere we could find, and the help centre returns 403 to automated fetches, so a scripted check will report nothing rather than report honestly.

The 65-character figure Sellura works to is our budget, derived from where the first line stops being readable in the feed. It is not a Depop rule, and we would rather say so than let our own number circulate as one.

Hashtags are the same story. Depop's walkthrough of listing an item gives the count, up to five, and no length for one; the 20 characters Sellura keeps each hashtag to, and the 1,000 it writes the whole description to, are ours too (re-checked 4 October 2026).

Walmart's field is 150 but its own guide asks for 50–75

Walmart Marketplace accepts a product name up to 150 characters, while Walmart's Listing Quality Optimization guide recommends 50–75. The two documents are both Walmart's.

Walmart also constrains the shape, not just the length: the brand goes first, the long description is a single paragraph of at least 150 words, and promotional wording, ALL CAPS and special characters are prohibited in the name.

Shopify's 70 is the SEO title, not the product title

Shopify's 70-character figure applies to the search-engine listing title — the one written into the page's <title> tag — which is a separate field from the product name shown on the storefront.

Shopify also allows far more tags than a listing needs: 250 per product at 255 characters each. Sellura writes to 20, because tags past that point are inventory organisation, not search.

Shopee recommends 25–100 characters; it does not publish a hard cap

Shopee's Seller Education Hub for Singapore asks sellers to keep the product name between 25 and 100 characters and the description to at least 100 (read 19 October 2026). Its developer guide says the hard limits differ by market and by type of seller and are served per shop through its API, so no single number on Shopee's current Singapore or Philippines pages is the cap.

The 100 Sellura works to is ours, set at the top of Shopee's recommended range, and the 3,000-character description budget is ours too. Numbers in older Shopee documents for other markets, and the larger caps in third-party guides, appear on none of the current Singapore or Philippines pages we read.

Shopee's rules are about the shape of the name as much as its length: each word capitalised, no promotional words such as "Hot Item" or "Best Seller", none of the symbols } ~ $ ^ { < ! * # @ ; % >, and no word repeated more than three times.

Facebook Marketplace's 99 comes from its listing form, and Meta publishes no limits

Meta publishes no title, description or photo limit for a personal Marketplace listing. Its Help Center, its Seller Agreement and its developer documentation state none for one (checked 24 October 2026). The developer documentation's numbers are for business partners' feeds in Europe, a different path. The figures of 100 or 150 characters that circulate online are not on any Meta page.

We read the numbers off Facebook's own Item for sale form on 24 October 2026, without saving or publishing anything. The title takes 99 characters, and at 100 the form asks you to shorten it. The form allows up to 20 product tags and up to 10 photos. It showed no limit on the description, which accepted 100,000 characters without a warning, so the 2,000 on this page is our budget. The account we read it in is not a US one, and Facebook can change its form without notice, which is why this page says "Facebook's form" and not "Facebook's rules".

Meta does publish limits for catalog products in Commerce Manager, a separate path used for ads and shops: a title of up to 200 characters, under 65 recommended, and a description of up to 9,999. Those are not the limits of a personal Marketplace listing, so they are not used here, except that our 65-character title aim borrows that advice.

Mercari's 80 and 1,000 come from its listing form, not its help

Mercari's help centre publishes no character limit for the title or the description. Searching it for characters, title length or description length returns nothing that states one (checked 22 October 2026).

The numbers are in the code of Mercari's own listing form: the title box stops taking characters at 80, and the description is refused over 1,000 characters or under five words. We read that code on 22 October 2026. It is the check Mercari actually runs, so a listing written to it will not be cut, but it is not a published rule, and Mercari can change its form without a notice. That is why this page says "Mercari's form" and not "Mercari's rules", and why the date matters more here than anywhere else.

Older figures of 40 characters describe Mercari in Japan, a different site. Three hashtags as a limit appears on no Mercari page or in its form.

Folksy's help says 1,500 characters for the description, and its form takes 2,000

Folksy's seller help says titles can be up to 80 characters and descriptions up to 1,500, and that a listing takes 15 tags with 255 characters for all of them together (checked 25 October 2026).

Folksy's own listing form agrees on the title, stops it at 80 and refuses a forward slash in it, but accepts a description of up to 2,000 characters. We read the form's code on 25 October 2026. We write to the published 1,500, because a description inside it is accepted under either number.

The 255 for tags counts every tag and the commas between them, and one tag has no length of its own. The 13 tags of up to 18 characters on this page are ours: 13 of 18 plus 12 commas is 246, so a full set always fits, and 18 keeps a phrase such as "handmade jewellery" whole. The form also allows up to 5 materials and 5 colours, and an optional Inspiration field that Folksy says is not used in search.

Temu publishes two limits for the description and the bullet points

Temu's product name is 500 characters in every version of its listing API and on its US, EU and global documentation, and a longer name is cut. Only letters, numbers and common punctuation are allowed. The figure of about 50 characters that circulates for Temu titles is not on any Temu page (checked 24 October 2026).

For the description, Temu's version 1 and 2 listing API refuses more than 2,000 characters, while its listing instructions and its version 3 guide say 10,000. For the bullet points, the same API and the table in the instructions say five of up to 200 characters each, while the text of the instructions says up to six points and 700 characters. Both answers are Temu's own. We write to the smaller one, 2,000 and five of 200, because a listing inside it is accepted under either reading.

Temu has no tags field in any version of its API, so the search keywords on this page are our budget. Its seller rates are not published outside the seller account, so Sellura has no Temu fee calculator.

Alibaba.com's three keywords have a count, not a clear length

Alibaba.com caps the product name at 128 characters in both of its listing APIs and in its 2026 supplier guide, and the description at 50,000 in the current API (60,000 in the older one). It allows exactly three Product Keywords, with no commas or semicolons inside one (checked 22 October 2026).

How long one keyword may be is less settled. The older API takes up to 256 characters per keyword; the current one takes all three as a single line of up to 384 characters, separated by spaces. A figure of 128 per keyword circulates, but no Alibaba.com page we could read states it, so this page does not either: the 60 in the table is our budget for a buyer's search phrase.

Alibaba.com's supplier training also asks suppliers to avoid + \ and quotation marks in the product name. That page dates from 2016 and says "avoid", not that the form rejects them, so read it as advice. The supplier's minimum order, prices and lead time are fields of their own, and Sellura never writes them.

AliExpress's 218 is its current API; the 128 and the 60,000 are from a retired one

AliExpress publishes its listing limits in its Open Platform API documentation, not in a seller help page we could read without an account. Its current posting API for overseas merchants, aliexpress.solution.product.post, takes a title of up to 218 characters (read 22 October 2026).

The 128 characters quoted in many guides comes from aliexpress.offer.product.post, an older API that is no longer in AliExpress's current list. That same older API is the only place a description cap is printed: 60,000 characters. The current posting APIs limit the description by the number of content modules instead, so this page prints 60,000 as the retired API's number, not as a current rule.

AliExpress's posting APIs have no keywords field. We found no official AliExpress rule on promotional words, capital letters or keyword stuffing in titles. Where Sellura avoids them, that is our rule, not AliExpress's. What a seller's own Seller Center form enforces can differ by type of seller and is only visible with an account.

TikTok Shop's 255 is the cap; 25 is the floor of its Good tier

TikTok Shop's listing API takes a US product title of 1 to 255 characters (Partner Center, Create Product and Edit Product API 202309, read 24 October 2026). Its US Academy listing quality guide, revised 8 July 2026, counts a title toward the Good tier from 25 characters, with the same maximum. TikTok Shop publishes no recommended length beyond "concise", so the 100 Sellura aims at is ours. Ranges of 40 to 150 or 25 to 200 characters printed in some guides are on none of the TikTok Shop pages we read.

The search terms are a real field: up to 15 terms and no more than 250 characters in all, hidden from shoppers and, in TikTok Shop's words, "only used in search engines". TikTok Shop sets no length for one term, so the 12 terms of up to 20 characters Sellura writes are our budget, 240 at most, inside the 250. The key product features are TikTok Shop's too, at most 5 and 1,500 characters in all, and the 250 per point is ours. Both fields are in the listing API without a regional exception; whether a given Seller Center form shows them we can't see without an account.

Two things we saw on TikTok Shop product pages on 24 October 2026 are observations, not published rules. The title in a page's preview tags is an AI-written rewrite, not the seller's, so a shared link can read differently from the listing. And some descriptions are images only, which leaves no text for search or for a checker to read.

Mercado Libre sets the title limit per category

Mercado Libre's developer documentation says the title limit is set by the item's category (max_title_length), and publishes it with each category. Read across every leaf category of its Mexican, Argentine, Colombian and Chilean sites on 19 October 2026, it is 60 characters in most, 200 for car parts and real estate, between 70 and 150 in a handful, and never below 60.

So the 60 on this page is Mercado Libre's own number for most categories, and a title of 60 or fewer fits every category. Many sellers now enter a family name instead of a title, within the same limit, and Mercado Libre builds the title from it and the attributes.

Google Shopping is a product feed, and Google has a rule for AI-written text

Google Shopping is not a marketplace: it is Google Merchant Center, where a store sends its products for Google's free listings and Shopping ads, and the sale happens on the store's own site. The 150-character title, the 5,000-character description and the 150 characters per product highlight are Google's, from its product data specification, read on 24 October 2026. Google advises using all 150 characters of the title, with the most important first, since shoppers usually notice only the first 70 or fewer. A feed has no keyword field, so the 8 search phrases of up to 40 characters on this page are ours, words to work into the title and the description. Google takes 2 to 100 highlights and recommends 4 to 6, and the 6 we write is the top of that.

Google asks for titles and descriptions created with generative AI to be sent in the structured_title and structured_description attributes, marked as trained_algorithmic_media, instead of title and description. Sellura writes with AI, so that applies to text pasted from it. When a product has both title and structured_title, Google uses title.

WooCommerce is a store plugin, and it publishes no field lengths

WooCommerce is not a marketplace: it is a free plugin that turns a WordPress site into a store, and shoppers reach its products through Google. Its documentation and REST API publish no length for the product name, the description, the short description or the product tags, and no count for the tags (read 25 October 2026). So every WooCommerce number on this page is ours: a name of up to 70 characters aimed at about 60, because WordPress makes the name the page's title in search results followed by the site name, 10 tags of up to 30 characters, because each tag gets its own landing page on the store, and 5 short description points of up to 100 characters.

The 5,000-character description is ours too, borrowed from Google: the official Google for WooCommerce extension sends the long description to Google Merchant Center by default, and 5,000 is Google's cap for a description there, so the same text can go to Google Shopping whole. WooCommerce's own code puts the short description, not the long one, into the product's structured data for search engines.

Wix: the product name caps at 80, and the title tag is built from it

A Wix store is the seller's own website, so the fields that matter for search are the ones Google reads. Wix's help, read on 25 October 2026, caps a product name at 80 characters and builds the page's title tag from the product name and the site name by default, recommending names of at most 60 characters: both of those numbers are Wix's. By default the meta description is the product description, and Wix recommends at most 156 characters for it, so the first 156 characters of the description are what a searcher sees unless the seller writes their own.

Wix publishes two description caps: 8,000 characters in its older catalog API and 16,000 in its current one and its product import template. The 8,000 on this page is the lower of the two, so a description fits a store on either catalog. A Wix product has no tags or highlights field, so the 8 keyword phrases of up to 40 characters and the 8 highlights of up to 80 are ours: words to work into the name and the description, and selling points for the description or an info section.

Squarespace's 100 is the SEO title, and it publishes no description length

Squarespace caps a product name at 200 characters and an SEO title at 100, and advises keeping titles to 70 characters or fewer (its help, read 25 October 2026). With no SEO title set, the product name is what search results show, so the cap on this page is the lower one: a name of up to 100 fits both fields.

Squarespace publishes no length for the product description, in its help or in its Commerce API reference, so the 5,000 on this page is our budget: the cap of Google Merchant Center, where Squarespace can sync a store's physical products. A tag can be 80 characters, but Squarespace gives no count, and its tags are filters on the store page rather than a ranking field, so the 10 tags of up to 40 characters are ours too. The SEO description has its own cap, 400 characters, with 50 to 300 advised and about 160 shown in search.

Grailed counts the title in words, and publishes no character length

Grailed's help and its How to Sell Guide publish no character length for the title or the description (read 26 October 2026). What Grailed publishes for the title is a word count: between 3 and 6 words, named the way the designer or retailer named the item, with the designer left out because it goes in a field of its own. So the 60-character title on this page is ours, room for six words of a model name, a colour and a material, and so is the 1,000-character description, a budget that holds the condition, the flaws, the tagged size and the measurements Grailed asks for.

The tags are Grailed's own numbers: up to 10 tags of 32 characters each, shown on the listing page and in search results. Grailed asks for the item's style, era, material, season or trend in them, says not to fill them with designers, and may remove tags unrelated to the item.

Whatnot publishes no length for a listing's title or description

Whatnot is a live-shopping app and marketplace, and its listings sell two ways: in a live show, where Whatnot's guide for new sellers says image and description are optional, and as Buy It Now listings in the seller's Profile Shop, found through Whatnot search between shows. Whatnot's help asks for a clear, descriptive title and says descriptive titles and relevant keywords help buyers find an item, but neither its help nor its Seller API gives the title or the description a length (read 26 October 2026).

So every Whatnot length on this page is ours: a title of up to 80 characters aimed at about 60, the cap eBay and Poshmark set, where resale listings are carried over from, and a description of up to 1,000 characters that refers only to the item, as Whatnot's Listing Guidelines require. A listing has no tags field either. Shows carry tags and one primary brand tag, so the 8 search keywords of up to 30 characters and the 5 details of up to 60 are ours too: phrases and points to work into the title and the description.

BigCommerce: a 250-character name, and page titles under 60

A BigCommerce store is the seller's own website, so its products are found through Google and the store's own search box. Both title numbers on this page are BigCommerce's, read on 26 October 2026: its Catalog API caps a product name at 250 characters and requires it to be unique in the store, and its help on SEO fields advises page titles of less than 60 characters that start with a relevant keyword. With no Page Title set, BigCommerce uses the product name as the page title, and its own example of a good page title ends with the store's name, so the store name counts against the 60.

BigCommerce publishes no length for the product description, so the 5,000 here is our budget: the cap of Google Merchant Center, where a BigCommerce store can send its products. Search keywords is BigCommerce's own field, a comma-separated list for the store's search box, not for Google, but it gives no count and no length, so the 10 keywords of up to 30 characters are ours. BigCommerce has no highlights field, so the 8 highlights of up to 80 characters are ours too, for the description or a custom field.

Primary sources

Where each number came from

Primary sources only — the platform's own help centre, developer documentation or seller guide. Competitor round-ups and “2026 review” posts are not used: they are how a stale figure spreads.

How this page is kept true

Every number above is the one the product runs on. The same registry drives the generator's prompt, the validator that rejects an over-length title, the scorer and the CSV export, so a figure on this page cannot be stale in a way the product is not.

Each marketplace entry records the date a human last opened the platform's own document and which documents those were. Both are printed beside the numbers rather than kept in the repository, so "has anyone checked since?" is answerable without asking us.

Caps are re-checked when a platform announces a change, when a listing we generate is rejected for a reason the registry did not predict, and otherwise on the schedule that produced the dates shown. A date that has not moved means nothing has changed, not that nobody looked — but it does mean the check is as old as it says.
