Mercado Libre titles: the length, the order and what to leave out

How long a Mercado Libre title can be

Mercado Libre's developer documentation says the title limit is set by the category the item belongs to, in a setting called max_title_length, and the category settings it publishes show the number. Read across every leaf category on its Mexican, Argentine, Colombian and Chilean sites on 19 October 2026, the limit is 60 characters in most categories, 200 in car parts and real estate, between 70 and 150 in a handful, and never below 60.

So a title of 60 characters or fewer fits any category, and a longer one is possible only where the category allows it. Pages that print one flat number for all of Mercado Libre are describing the most common category limit, not a rule for every listing.

The order: product, brand, model, specifications

Mercado Libre's help gives the structure directly: product, brand, model of the product and some specifications, at least three words, separated by spaces, with no punctuation marks or symbols. The product comes first because it is what a buyer types first; the brand and the model narrow it; the specifications separate it from the next listing.

Mercado Libre's own example is "Microondas Grill BGH Quick Chef B223D plata 23L 220V". It includes the colour, plata, although the same page asks sellers to put colours in variations, so treat the example as a picture of the order and leave the colour out of yours.

What stays out of the title

Most of what sellers put in a title to sell harder is what Mercado Libre's help asks them to leave out. Each item on the list below has a place elsewhere in the listing, which is why it does not belong in the title.

Another brand is the one exception with a rule of its own: it may appear only to say what the item is compatible with, using "para" or "compatible con". "Tipo", "símil" and "igual a" are not allowed, because they borrow a brand the item is not.

• The colour: create a variation for each colour instead.
• The condition, new or used: it goes in the item's characteristics.
• Free shipping, returns and instalments.
• Stock: mentioning it is not allowed.
• Discounts and promotions.
• Punctuation and symbols: separate the words with spaces.

User Products: when Mercado Libre writes the title

With User Products, Mercado Libre's newer way of listing, the seller sends a family name instead of a title, no longer than the category's title limit, and the documentation says the title field should not be sent: Mercado Libre completes it automatically from the family name and the attributes.

That changes what a good title starts from. A family name that reads as a clean product name, with no colour, size or condition in it, and a complete ficha técnica are what Mercado Libre builds the title from, so the attributes now do part of the title's work.

Mercado Libre's own help, and where Sellura fits

Mercado Libre gives sellers two tools for this. "Sugerir un título" proposes a title with AI while you list, and "Calidad de la publicación" scores a listing from 0 to 100, in three levels, Básica, Estándar and Profesional, with what to improve. Both are part of the seller account and worth using.

Sellura does a different job on the same fields. It writes the title, the ficha técnica and a plain-text description in Spanish from your description of the item, applies the rules above, gives the result a deterministic 0–100 score, so the same listing always gets the same number, with one concrete fix per weak point, and writes the same product for Amazon, eBay and the other marketplaces it supports if you sell on more than one.

What Sellura does here, and what it doesn't

Describe the item and Sellura returns a Spanish title of 60 characters or fewer, which fits every category, in product, brand, model and specifications order, with no colour, condition, shipping, instalments, stock or discounts, plus a ficha técnica of the attributes a buyer checks and a plain-text description, for Mexico, Argentina, Colombia or Chile.

The score and the title preview are free on every generation, with no card, and so are the title checker and the Mercado Libre fee calculator. A credit unlocks one finished listing: Starter is $15 a month for 25 credits or $150 a year, and Pro is $24 a month for 65 credits plus bulk, or $240 a year. A listing you already have goes through the Listing checker: paste its title and description for a 0–100 score and the fixes worth making first, with 2 free checks before it asks for a free account. Sellura doesn't open Mercado Libre links, whose pages sit behind a login and whose robots.txt asks crawlers like ours to stay out. It doesn't post to Mercado Libre or track rankings, and it has no research database or ads analysis.
