GEO for marketplaces

When shoppers ask where to buy X, AI often cites Mercado Livre, Amazon, or Magalu. Marketplaces and sellers need to know whether the brand makes the recommendation or only the channel does.

Who it is for

Brazilian marketplaces, 3P sellers with a house brand, and platforms that aggregate stores. Growth and category managers competing for where to buy in AIs.

Where-to-buy prompts

  • Where to buy an iPhone in installments in Brazil
  • Best marketplace to sell handmade goods
  • Mercado Livre vs Shopee for electronics
  • Official brand store or marketplace?

Monitor channel versus brand

Split where-to-buy (channel) prompts from best-brand (product) prompts. MencionAI shows whether AI recommends the marketplace, the seller, or the official store.

Content beyond the feed

Feeds alone do not explain trust, shipping, or warranty. Publish category hubs, clear policies, ItemList, and purchase FAQs. Sellers: brand pages on your own domain, not only the listing.

Share of voice among channels

ML, Amazon, Magalu, Shopee, and Americanas dominate generic prompts. Find categories where a smaller player or the house brand is still cited.

Measure citations and plan by category

ARS and mentions per category prompt guide which hubs to create. MencionAI turns the gap into a checklist: policy, schema, channel comparison, and llms.txt.

Frequently asked questions

Does AI recommend marketplaces or official stores?

It depends on the prompt. Cheap where-to-buy pulls marketplaces; trusted official store pulls brands. MencionAI measures both so you do not optimize the wrong prompt.

Does a seller need their own site for GEO?

It helps a lot. Without a domain, AI only has the listing and the marketplace. A brand page with catalog, FAQ, and schema increases direct citation.

Does Product schema work on a marketplace?

Yes, on indexable product and category pages. ItemList on category hubs and Offer with price/availability (when stable) make the offer more explicit to models.

How do I avoid being just another Mercado Livre in the answer?

Differentiate on specialty, curation, regional shipping, or house brand. Niche prompts reveal space that generic prompts hide.

Does GEO replace marketplace category SEO?

No. Category SEO and paid media still matter. GEO adds the AI channel, where the answer may cite a single channel instead of ten search ads.
