Mercado Libre keywords: where they go, and how to find the ones buyers type
Por Oleksandr Shaniuk · fundador de Sellura · Actualizado el 1 de noviembre de 2026
Mercado Libre has no tags or keywords field, so a keyword works only where you put it: in the title, in the ficha técnica's attributes, or in the description. Its developer documentation calls the title the key to buyers finding a product and sets its length per category, asks for every specification to go in the ficha técnica first, and says a plain-text description gets a better result in searches (Mercado Libre Developers, Publicar productos updated 9 January 2026 and Descripción de productos updated 13 March 2026, read 1 November 2026).

To find the words buyers type, Mercado Libre's own data beats any list: its trends resource returns the 50 most popular searched products per country, updated weekly and filterable by category, and its best-sellers resource the top 20 in a category. Below: what goes in each field, the words that look like keywords but belong in a setting, a worked example from our title checker, and where the searched words come from.

Where a keyword can go
Each of the three fields takes a different kind of word. The title takes the product, the brand, the model and a few specifications, in that order. The ficha técnica takes the attributes a buyer filters by, and its required ones and the product's universal code (GTIN) also feed Mercado Libre's quality score, which tells sellers that a GTIN keeps a listing higher in search results. The description takes what the other two can't say.
So the question is not how many keywords to add but which field each one belongs in. A word in the wrong field is either wasted or, in the title, a reason for Mercado Libre to moderate the listing.
| Field | Put here | Mercado Libre's rule |
|---|---|---|
| Title | Put hereProduct, brand, model, specifications | Mercado Libre's ruleLength set by the category, 60 characters in most; no colour, condition or stock |
| Ficha técnica | Put hereBrand, model, material, size, compatibility, GTIN | Mercado Libre's ruleComplete the required attributes first; they count toward listing quality |
| Description | Put hereUse, contents, care, warranty, answers to common questions | Mercado Libre's rulePlain text, no HTML; it complements the ficha técnica rather than repeating it |
From Mercado Libre's developer documentation (Publicar productos, Descripción de productos, Calidad de publicaciones), read 1 November 2026. "60 in most" is our count across every leaf category on 19 October 2026; the limit itself is Mercado Libre's, set per category.

The words that look like keywords but belong in a setting
The words sellers most often push into a Mercado Libre title are not searches for the product at all: the colour, envío gratis, meses sin intereses, nuevo, stock. Mercado Libre's rules put each of them somewhere else. The colour becomes a variation, so one listing carries every colour. The condition goes in the attributes. A mention of stock gets a listing moderated.
Free shipping and instalments are settings, and Mercado Libre rewards them there: its quality score lists "Ofrecé envío gratis" and "Agregá cuotas al mismo precio" among the actions that make a listing more competitive. Typed into a title, they spend characters and earn nothing.

A worked example from our title checker
We ran the title in the figure through Sellura's free title checker on 1 November 2026. Termo Stanley Negro Original Envío Gratis 12 Meses Sin Intereses is 64 characters, over the 60 that fits every category, and the checker flagged envío gratis and meses sin intereses as promotional phrases and Negro as a colour that belongs in a variation. Apart from the brand, it names no specification a buyer filters by.
The rewrite, Termo Acero Inoxidable Stanley Classic 1 L Tapa Taza, is 52 characters and the checker found nothing to remove. It follows Mercado Libre's order: the product (termo), what it is made of, the brand, the model, the capacity and the lid. Capacity and material then go in the ficha técnica as well, where a buyer's filters can find them.

Where to find the words buyers type
Start with Mercado Libre's own search box: type the first word of your product and read the completions, which are searches buyers on that country's site make. Then look at the titles of the best sellers in your category, which show the words and the order that already sell. For more than that, Mercado Libre publishes its own search data to developers:
- Trends: the 50 most popular products searched per country, updated weekly, for Argentina, Brazil, Chile, Mexico, Colombia, Uruguay and Peru, and filterable by category.
- Three readings: the fastest growing (by revenue over the last week), the most wanted (by search volume over the last week) and the most popular (searches up sharply on two weeks earlier).
- Best sellers: the top 20 items or products in a category, also filterable by brand.
- Both need an access token from a Mercado Libre app, so they are for a seller with a developer or an integrator, not a public page.

Keywords in the description, without repeating the ficha técnica
Mercado Libre's advice for the description is to load every specification into the ficha técnica first, then write only what isn't there, organised with capitals, dashes and spacing, and short. It also says plain text gets a better result in searches than formatted text, loads faster and displays on every device.
That makes the description the place for the words a buyer uses that are not attributes: what the product is for, who it suits, how it is used, what comes in the box. Write them as sentences a buyer reads, in the country's Spanish, not as a list of search terms.

What Sellura does here, and what it doesn't
Sellura has no Mercado Libre search data and no keyword database, and says so: its keyword ideas for Mercado Libre are built from your own words, not from Mercado Libre's searches. What it does is put the words where Mercado Libre wants them. Describe the item once and the generator returns a Spanish title of 60 characters or fewer in Mercado Libre's order with no colour, condition, shipping or instalment words, a ficha técnica of the attributes a buyer checks, and a plain-text description of what the ficha técnica can't say.
The title preview and a 0–100 score are free on every generation, no card; the score is deterministic, and each weak factor comes with one fix written for that listing. A credit unlocks the finished listing, and the first unlock is free on a new account. Starter is $15 a month for 25 credits ($150 a year) and Pro $24 a month for 65 credits plus bulk ($240 a year). Sellura doesn't open Mercado Libre links, post to Mercado Libre or track rankings.

How long can a Mercado Libre title be?

Move the colour to a variation and free shipping and instalments to their settings, where Mercado Libre's quality score counts them.
