On my Macbook Air, half of the ad is visible. My competitors have 7 ads, excluding popups. One of which is before any content, right at the top of their page and they appear totally uneffected. I would rather be poor, than spam my website in such a manner.
The problem appears to have started January 18-19th.
The advert is to the right of the artwork.
The comments come below the artwork and ad.
Hope that makes sense.
I always hoped some day, Google would penalise websites that spam their pages with ads, and I could then take credit, for doing the right thing for my users.
When this drop happened and coincided with the update, it was like somebody kicked me, full force, right in the balls.
