In one sentence
An online marketplace is a site like Amazon, Etsy, eBay or Walmart Marketplace where many sellers list products side by side, so you reach the site's shoppers but compete on the same page as rivals.

Why marketplaces matter for AI search
Marketplace listings often rank well and carry lots of reviews, so AI assistants may cite them when recommending products. A strong marketplace listing can get your product named even when the answer links to the marketplace instead of your store.
Keep product names, specs and prices consistent between your store and your listings, so assistants don't get conflicting facts.
How to use marketplaces alongside your own store
- Use marketplaces to reach new shoppers, and your store to keep them.
- List core products there, and keep bundles or exclusives on your site.
- Include a reason to visit your store in your packaging, like a care guide or reorder page.
