Keywords - Criteo Docs

A Few Things to KnowShoppers browsing through the retailer’s search page may utilize search for phrases associated with line item products where the line item may not be allowed to search on that page. Similar to this scenario, the shopper can also enter search phrases that align with products permitted to serve on a page. The keyword API endpoint allows you to control your Onsite Sponsored Products line item by providing visibility to users what keywords are applied to line items, and also allows for users to determine which keyword to target positively or negatively. The endpoint can also provide keyword bidding capabilities to optimize line items based on relevant keywords.Check out the Onsite Sponsored Products page for a complete summary of Criteo’s keyword service.

Get Recommended Keywords by Line Item

This endpoint retrieves a collection of recommended keywords for a line item, created automatically by our keyword models.

A FEW THINGS TO KNOW

Only the top 100 keywords will be returned
Automatic recommended keywords can change day to day, as are determined based on click volumes by users on Retailer’s environment. Although significant changes are not expected, it is possible that the long tail of the top 100 keywords change slightly

Add or remove Keyword from Line Item

Negative Targeting v1The negative keyword targeting in this API will eventually replace the Negative Keyword Targeting endpoints. You may continue using those endpoints without disrupting your services. We recommend reviewing and testing the new Keyword endpoints to prepare for a future migration to these new endpoints.
