Criteo must log a minimum number of hits from the Criteo OneTag in order to assess the quality of the feed and tag implementation.
What is feed quality?
Feed quality is the ratio of matches between the Product IDs passed on the Criteo OneTag and the displayable Product IDs from the product feed.
If there are 10,000 Criteo OneTag event hits, and 9,500 Product IDs in those events match a displayable Product ID from your feed, then the feed quality is 95%.
What is tag quality?
Tag quality is measured by taking into consideration multiple variables such as number of hits on each Criteo OneTag per page (Homepage, Search Listing, Product Listing, Basket and Sales Confirmation), along with any warnings and errors. Click here for a detailed list of warnings and errors you may encounter.
The number of hits per page where the Criteo OneTag is implemented on your site (Homepage, Search Listing, Product Listing, Basket and Sales Confirmation pages) must match the number of hits/page views as recorded by your main analytics package (Google Analytics etc). If these figures do not match, please check here for more information.
