Mercado Libre SEO: the title, the ficha técnica and the description
Mercado Libre SEO rests on three parts of a listing: the title, the ficha técnica and the description. The title limit is set per category, and across every category on Mercado Libre's Mexican, Argentine, Colombian and Chilean sites it is 60 characters in most, 200 for car parts and real estate, and never below 60 (Mercado Libre's developer documentation and its published category settings, read 19 October 2026). Its help asks for the product, the brand, the model and a few specifications, in that order.

Mercado Libre's numbers checked against its own pages on 2026-10-19. The ones marked ours are Sellura's budgets, not Mercado Libre rules. Sellura generates within all of them automatically.
The ficha técnica is the category's list of attributes, and Mercado Libre marks listings whose technical specs are incomplete, which lose positions. The description holds up to 50,000 characters of plain text. Listings are in Spanish, and Sellura writes them in Spanish for Mercado Libre in Mexico, Argentina, Colombia and Chile. Below: how each part works, what to leave out, and what Sellura writes.
How a Mercado Libre listing gets found
Mercado Libre's help on writing a good title gives the order: product, brand, model and some specifications, at least three words, separated by spaces with no punctuation or symbols. It also lists what stays out: the colour, which belongs in a variation per colour; the condition, which goes in the attributes; free shipping, returns and instalments; stock; and discounts or promotions. Another brand may appear only as compatibility, with "para" or "compatible con", never with "tipo", "símil" or "igual a".
There is a change most guides miss. With Mercado Libre's User Products, many sellers no longer type a title: they send a family name, within the category's limit, and Mercado Libre completes the title itself from that name and the attributes. 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 that system builds a good title from.
- Title: the limit is set by the category, 60 characters in most categories. Product, brand, model, specifications.
- Leave out: colour (use variations), condition, free shipping, instalments, stock, discounts.
- Ficha técnica: the category's attributes, complete. An incomplete one is marked and loses positions.
- Description: up to 50,000 characters, plain text only, no HTML, links or emoji.
- Photos: up to 12 per item in most categories; a white background on the first one.

Writing the title, the ficha técnica and the description
Build the title in Mercado Libre's order: "Audífonos inalámbricos Sony WH-CH520 Bluetooth 50 h" is 51 characters and names the product, the brand, the model and two specifications, with the colour left for the variations. Then fill every attribute the category offers, the required ones first: the brand, the model, the material, the measurements and what the item is compatible with are what the ficha técnica is for, and the title should not have to carry them.
The description is for what neither holds. Mercado Libre's help on descriptions asks for plain text, no HTML and no links, and suggests short lines, the words buyers use, and answers to the questions buyers ask most, without repeating the ficha técnica. Emoji are rejected by its listing API.
- Mercado Libre's own tools: a 0 to 100 "Calidad de la publicación" score (Básica, Estándar, Profesional) and a "Sugerir un título" button that proposes a title with AI. Both are worth using; Sellura adds a score with a fix for each weak point and the same product for other marketplaces.
- Spanish is the language of the listing on every one of these sites; write for the country you sell in.
- Ours, not Mercado Libre's: the 8 keyword phrases of 30 characters, the 8 attributes of 40 characters Sellura suggests, and the first 150 characters of the description that we write the searched words into.

What Sellura does
How Sellura writes for Mercado Libre's format
- Describe the item once and Sellura returns a Spanish title of 60 characters or fewer, which fits every category: product, brand, model and specifications, with no colour, condition, shipping, instalments or discounts. 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.

- The same product written for Amazon, eBay and the other marketplaces Sellura supports, each to its own rules, if you sell on more than one.
- Sellura doesn't open Mercado Libre listing links: its pages answer with a login wall, and its robots.txt asks crawlers like ours to stay out, which we respect. To check a listing you already have, paste its title and description into the box above or the free Listing checker, for a 0–100 score and the fixes worth making first.
- The finished listing costs 1 credit, and the first unlock is free on a new account.
