Now Ads from Facebook Audience Network can be brought via Google's Open Bidding Program. With this initiative, advertisers can maximise advertising revenue.
It was in the month of March 2017, that header bidder was first added for Facebook Audience Network. Now the company in the month of June has also added bidding support for in-app ads.
The logic here is simple that the more advertisers compete harder for the same advertising space, the more they will increase the revenue. It is clear sign that Facebook is is now privileging publishers over advertisers.
