Hello,
We are running a website that requires different formats for mobile ads.
What is the best practice method for serving the same ad in two different formats to Desktop and Mobile users.
Currently, it seems like the only way is to have two separate zones, and two separate ads, and hide/display the zones based on media queries. However, doing it this way also seems to indicate that impressions will double, and our CTR on ads will go down.
Cheers,
Lee
