For a while I've had certified ad networks turned off. Out of desperation in the decline pf revenue over the past few months, I decided to allow them to hopefully increase eCPM.
My issue is that it's been 5-6 days now and 0 certified networks show impressions in my stats on 3 sites? I have checked the settings twice and they are all enabled. Is this normal for it to take a week or so? Any ideas? Thanks.
There is no normal with AdSense anymore - that's been pretty much established. I have pages with unique ad units that during the day shows pageviews when I check reports. However when I check stats the next day the reports say there were 0 pageviews for that ad unit. AdSense reporting is shaky at best these days - been this way for a while. It's hard to use the data to make decisions anymore. But to answer your original question, it sounds like you are encountering the same reporting error (lack of impressions) that I am seeing.
