This has been talked about as an obvious evolution for the Ads Network for quite a while. Do anyone with knowledge in this area , know why is taking so long for Adsense/ Criteo come up with a solution like this?
The ad network needs to trust the website to not only deliver the ads reliably but also to report back correct data (impressions, clicks, etc). We are talking about quite a lot of money here.
The way I understand it, SSAI is a video solution because you don't have to worry about impression (you have the view count), just the click so it can be done server side. Google has their own SSAI solution they call DAI. Criteo doesn't do it mainly because they have low video inventory. Correct me if I'm wrong.
