Mercari SEO: the title, the description and what its search weighs
Mercari SEO rests on two pieces of text and a few fields picked from lists. Mercari's help on search says it prioritizes listings with clear, relevant and accurate keywords that buyers would genuinely use, and its listing help asks for the brand to be stated clearly and for a category and condition to be set. Mercari's help prints no title or description length: its listing form stops the title at 80 characters and the description at 1,000, which we read in the code of that form on 22 October 2026.

Mercari's numbers checked against its own pages on 2026-10-22. The ones marked ours are Sellura's budgets, not Mercari rules. Sellura generates within all of them automatically.
There is no tags field, and Mercari asks sellers not to add brand names and hashtags that have nothing to do with the item. Its search also weighs the seller, not only the listing: smooth sales, verifications and quick replies. Below: how search reads a listing, what holds one back, and what Sellura writes for each field.
How Mercari search finds a listing
Mercari's help on search names what its ranking considers. For the listing, keywords: clear and descriptive terms that accurately portray the item, the words a buyer would actually use, with irrelevant terms left out. For the seller, lifetime and recent performance: sales completed smoothly with few cancellations or returns, recent sales, contact details, payment methods and ID verification kept current, and engagement such as answering messages and shipping on time. Mercari does not say how much each one weighs.
Two more lines matter to anyone refreshing old stock. Mercari says its system favors genuine updates over listings that are frequently deleted and relisted, so edit a listing instead of posting it again. And its listing help says the more accurate a listing is, the higher it appears in search results.
- Title: up to 80 characters, where Mercari's listing form stops; its help prints no length. Brand, item type, model or style, size and colour, each once.
- Description: up to 1,000 characters and at least five words, both from the form's code. Open with what the item is, then condition, flaws, measurements and what is included.
- Brand, category and condition are picked in the form. Mercari says stating the brand improves visibility, and that a category and condition help search.
- No tags field: the words buyers search for go into the title and the description.
- Up to 12 photos. The first one is what shoppers see first.

Writing the title and the description, and what holds a listing back
Write the title as a buyer's search: "Nike Air Max 90 Sneakers White Men's Size 10" is 44 characters and names the brand, the model, the item type, the colour and the size. There is room left under the 80 for one more true detail, such as the condition, and none of it should go on adjectives nobody searches for. Then say what the item is again, in plain words, in the first line of the description, followed by condition and any flaws, measurements and what is included.
Mercari has no tags field, so the search keywords Sellura suggests are phrases to work into the title and the description, not a box to fill. Never borrow another brand to reach its searches: Mercari's listing help asks sellers not to add brand names and hashtags that aren't associated with the item, and its Marketplace Guidelines prohibit listings that give false information.
- Deleting and relisting: Mercari favors genuine updates over frequent delete-and-relist, so refresh the information, photos or price instead.
- Your profile: verify your email, phone, a credit card and your government ID, the first steps Mercari's help gives new sellers.
- Off-app deals: Mercari's guidelines prohibit taking a transaction off the app, so keep contact details out of the description.
- Ours, not Mercari's: the 5 search phrases of 30 characters, the 5 details of 40 characters and the first 150 characters of the description that we write the searched words into.

What Sellura does
How Sellura writes for Mercari's format
- Describe the item once and Sellura returns a title inside the 80 characters Mercari's form takes, made of the words a buyer types, brand and item type first, each once. The title preview and a 0–100 score are free on every generation, no card. The score is deterministic: the same listing always gets the same number, and each weak factor comes with one fix written for that listing.
- A description inside 1,000 characters that opens with what the item is, then condition, flaws, measurements and what is included, plus five search phrases to work into the title and the description, since Mercari has no tags field.
- The same item written for Poshmark, eBay and the other marketplaces Sellura supports, each to its own rules, if you cross-list.
- The free Listing Grader reads public Mercari listing links and scores the title and description, usually in a few seconds. If a listing can't be opened, we say so rather than score it.
- The finished listing costs 1 credit, and the first unlock is free on a new account. Starter is $15 a month for 25 credits or $150 a year; Pro is $24 a month for 65 credits plus bulk, or $240 a year. Sellura doesn't post to Mercari, promote items or track where a listing ranks, and it has no research database or ads analysis.

The Grader reads public Mercari listing pages (mercari.com/us/item/…), usually in a few seconds. If a listing can't be opened, it shows as "couldn't open" rather than a score.
