Filtering Assist
Stay organized with collections
Save and categorize content based on your preferences.
You can use Filtering Assist to reduce the amount of bids that are filtered
from the auction. Filtering Assist predicts up to 50 creatives for a given bid
request that are likely to be filtered based on your recent bidding history.
Once enabled, you can view a list of creatives that are likely to be filtered
in BidRequest.imp.ext.excluded_creatives. See
ExcludedCreative
for details.
The creatives returned by Filtering Assist are likely to be filtered from the
auction, so we recommend that you don't use them in your bid response.
The list of excluded creatives is specific to a single bid request. You need to
review this list for each bid request to avoid excluding creatives that could
win the auction.
See the Bid
Filtering
guide for more ways to reduce your bid filtering.
