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 open auction line item by determining which keyword to target positively or negatively. The endpoint also provides keyword bidding capabilities to optimize line items based on relevant keywords.

Check out the open auction overview page for a complete summary of Criteo's keyword service.
