Due to campaign or other planning reasons, we want to deliver ads to only some categories.
Some product images cannot be used as advertisements
However, if you blindly delete records from your data feed, you will encounter a "tag and feed mismatch" as shown below.
Even if you remove an item from your data feed, as long as the product is still on your site, users will still visit it and the tag will still fire.
When a tag fires, the platform's engine checks the feed for matching items.
The item is not present in the feed and is treated as a "no match"
In dynamic ads, ad banners are automatically generated based on the feed information based on the product (product ID) viewed by the user. If the match rate between the tag and the feed is low, the ad delivery engine will not function ideally, and there is a possibility that irrelevant ads will be delivered.
Please note that with Criteo and RTB House, if the mismatch rate between tags and feeds exceeds 30%, your ad may fail the delivery review when starting or resuming a campaign.
