Are you looking in the AdSense portion of Analytics, or just straight pageviews?

I'm comparing Audience-Overview-Pageviews on Analytics to Page Views in the Adsense reports (on www.google.com/adsense).

Concidentally, the AdSense portion of Analytics is also reporting less pageviews.

I'm confuzzled.

jmorgan, do you run your ads through DFP? I am experiencing the same thing and I think this is an issue after the DFP outage last week. Been flagged to Google, they are investigating.

I have one ad unit through DFP and the rest direct Adsense ad units.

I can understand a slight discrepancy here and there between the two reports but when one is telling me I'm having record traffic and the other says that traffic is actually down the week before, something just doesn't seem right.

Check your "unmatched ad requests" - has it gone up? Mine has skyrocketed, despite 100% coverage.

If you use link units, your unmatched ad requests will skyrocket. (That's probably not the only reason, but it's definitely one of em)

Can't hurt to double check your Analytics implementation either. I use the Chrome extension Tag Assistant (by Google). Most of my sites use Google Tag Manager, but it also checks for other Google codes and tags as well.

I deactivated all my text link ad units and the # is still huge. To put it into perspective, for the last many months I am looking at < 100 per month and just for today, at 8AM - without link units - it is 29,000.

As was stated, this has only recently begun since last week so I doubt this is an implementation issue, especially if I know of at least 3 or 4 others who are also experiencing the same issue starting at the same time. Finally, Google told me this may be a bug/glitch and they are escalating it to their engineering team.

FYI, this got fixed by Google engineering team as of a couple of days ago.
