Keywords

📝
A Few Things to Know
Shoppers 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.
