Shopify product tag generator

Three numbers, and the gap between two of them

The first is Shopify's ceiling, the second is what this tool actually hands you, and the third is the one that decides how much any of it is worth for Google. Where a platform's ceiling and our output disagree, this page prints the smaller number.

Shopify's tag ceiling

250

tags per product, up to 255 characters each. A ceiling, not a target — and order tags stop at 40, so the 255 isn't universal either.

What this builder returns

13

tags, each up to 20 characters, on every marketplace it serves. Fewer than Shopify allows, and the honest number to put on the button.

Tags a search engine reads

0

Shopify's help centre states that tags aren't used by search engines, and tells merchants not to use them to improve store search results.

What Shopify tags do — and don't do

Tags in Shopify are organizational: they feed your storefront's search suggestions, drive automated collections (“add every product tagged pour-over to Coffee Gear”), power theme filtering, and make admin bulk-edits bearable. Shopify allows up to 250 tags per product at up to 255 characters each — a ceiling, not a target, and one nobody sane approaches.

What tags don't do is rank you on Google, and this is not an inference from silence. Shopify's own help page on tag formats says tags aren't used by search engines, and follows it with an instruction not to use tags to try to improve your store's search results, pointing merchants at its SEO keywords page instead. That's why this page won't promise “SEO tags”: it gives you clean store organization and sends the SEO effort where it pays.

• Good tags are reusable across products: material (ceramic), use (pour-over), audience (coffee gifts), collection logic (new-arrivals).
• Keep one consistent format — “Pour Over” and “pour-over” become two different filters.
• 8–15 well-chosen tags beat 100 one-offs; a tag used by a single product organizes nothing.
• Automated collections match tags exactly — decide the vocabulary once, then stay inside it.
• A tag is worth keeping only if you can name the second product you'd put it on.

Why the number here is 13, not 250

Until 24 September 2026 this page put Shopify's ceiling next to the button — 250 tags per product, 255 characters each — above a tool that returns thirteen tags of twenty. Both numbers were true about something. Only one of them was true about what you were about to get, and an attentive visitor would have counted the chips and caught it in ten seconds.

The rule now is mechanical, and a test enforces it: what a page promises is the smaller of what the marketplace allows and what the builder can actually produce. On Etsy and on Depop those numbers meet exactly — thirteen tags of twenty, five hashtags of twenty — so the difference was invisible until Shopify, whose ceiling sits far above ours, made it visible.

Why the builder stops at thirteen of twenty is worth saying too, because it is a choice rather than a bug: it normalizes every set against the strictest cap in the group, so a tag you build here is portable to any of them without being rejected or silently cut. Shopify is the only platform where that costs you headroom, and on Shopify the headroom is worth very little, for the reason in the next section.

The Shopify rule that no other marketplace here shares

Every other platform Sellura writes for treats its keyword field as a search input. Etsy indexes thirteen tags and its own guidance tells sellers to put the phrasings that wouldn't fit the title into them. Depop's five hashtags sit inside a description its search matches against. Amazon has search terms. Walmart reads its category attributes. eBay has no tags at all, and compensates with item specifics that its optimization guidance calls descriptive keywords.

Shopify is the exception, and it says so itself: tags aren't used by search engines. A Shopify store doesn't rank inside a marketplace search box — it ranks on Google, and Google reads the product title, the description, the URL and your structured data. Tags are invisible to it. That single sentence is why a Shopify tag strategy and an Etsy tag strategy have nothing in common except the word tag, and why porting a thirteen-tag Etsy set into a Shopify product does nothing for your traffic.

It is also, bluntly, uncomfortable for the apps that sell “SEO tags” for Shopify. The sentence is on Shopify's own help page, dated by us to the day we read it, and anyone can check it in one click.

So where does Shopify SEO live?

In the fields Google does read. The SEO page title — distinct from the product title — takes up to 70 characters, and Shopify recommends keeping it to 60 or fewer so search engines don't shorten it. The meta description is a recommendation rather than a cap: Shopify advises around 160 characters and publishes no hard maximum, which means the first sentence of your description is doing the work whether you wrote it for that or not.

Then the parts nobody edits: the product URL handle, the image alt text, and the structured data your theme emits. None of them is a tag, and all of them are read.

One limitation worth knowing before you go looking for it here: Sellura's Listing Checker grades a listing from its public URL, and it can't do that for Shopify. Shopify stores run on custom domains, so there is no fixed host to fetch and no pattern that could tell your store from anyone else's — URL grading and converting are switched off for Shopify by design, not broken. Paste the text into the generator instead.

A tag vocabulary that actually groups things

The failure mode in a Shopify admin isn't too few tags, it's a vocabulary that drifted. Six months in, a store has ceramic, Ceramic, ceramics and ceramic-ware, and four automated collections that each catch a quarter of the products they were meant to. Automated collections match the tag text exactly, so casing and hyphens are not cosmetic decisions — they are the difference between a filter that works and one that looks like it does.

Decide the axes once, then let every product be tagged along them: material, use, audience, collection logic, and season or drop if you run them. Four to five axes gives you eight to fifteen tags per product and a filter system a customer can actually navigate. Everything past that is admin you'll be maintaining rather than a customer benefit.

The generator above is deliberately a candidate machine, not an authority. It gives you thirteen phrases built from your own words; your job is to keep the ones that belong to an axis you already use and delete the rest. A good session with it ends with fewer tags than it started.

What the free tags don't do

This tool takes one line of input and returns candidates, by rule, for free, without an account. It doesn't know your catalogue, so it can't tell you which of its suggestions you already use — that judgement is yours.

• Free here: up to 13 candidate tags of ≤20 characters, from one keyword.
• In the generator: an SEO page title inside Shopify's 70-character field (aimed at 60), a description whose opening is written to be the meta description, highlights, and the tags — from a description of the product rather than a seed phrase.
• Plus a 0–100 score on what comes back, four listing languages, and the same set for every other marketplace Sellura supports, if you sell in more than one place.
• What none of it does: read your sessions, your conversion rate or your Google position. Sellura can't see them, so it never reports them.

A worked example, straight from the generator above

Typed into the tool at the top of this page: ceramic pour over coffee dripper. Thirteen candidates came back — the same thirteen every time, because this is a rule-based builder, so you can check it yourself.

The contrast worth studying isn't good tags versus bad tags. It's a vocabulary versus a pile.

Note what the builder does with a four-word seed: it takes adjacent pairs out of your own phrase first, then appends modifiers to the head noun. That is why the first four are usable and the tail is generic — and it is the honest ceiling of a tool that has four words to work from, rather than a product description.
