Seeing a huge drop in CTR and Revenue on June 29 and 30.
Traffic is more or less the same as usual.
Any problem with google adsense or are we cursed?
Got in touch with my adsense manager, the reply: 'Click spam rate increased since June 30"
I doubt it since traffic is as usual :(
This issue is not due "nessie", in fact, clicks are registered then disappeared in a very weird fashion.
The Nessie issue and clicks disappearing are two different things. A month or so ago google began removing the invalid clicks from the report whereas before they only removed the income and left the clicks in the count. This is why you see the clicks disappear.
The sudden reduction in CTR is exactly what occurred on 9 Mar when google removed Nessie arrows from a ton of sites. Text ads took the biggest hit, mostly on desktop browsers.
My site was hit that day. Ads had lots of space around them and it would have taken a moron to think they were anything but ads. I tested this theory by placing borders around the ads. The CTR dropped with the borders. I guess there are more morons than I thought.
I reconfigured the layout of the pages to place ads at the top and bottom, nothing half way down, which was the most clicked ad space.
After a while I still couldn't get any love from google, so I started giving adsense less ad space and replaced those adunits with another advertiser, creating more competition for my digital realestate. This caused an initial drop in income, but the income has since been rising each week and is higher and more stable than when I had adsense only.
Also, I found a couple of adword advertisers running ads with fake "search" buttons that were designed to look a lot like my site and their ads seemed to trick people into clicking. I began blocking all ads like these. If the advertiser redid the fake search ad under a different ad account I banned the advertiser's url altogether. After that I ended up with less disappearing clicks throughout the day.
Play their game by all means but remember that you don't know the rules...
To play a game one needs to know the rules, otherwise you are merely a pawn, yes?
