I brought up a question in this thread [webmasterworld.com
]that probably requires its own thread.
About 2 months ago I got the following message in my adsense account.
A new 160x600 ad unit on *********.com will improve your ad performance
I ignored it as it would have required a change to a custom theme and I didn't really want to go through that process, the site was using 120x600.
However quite dramatically my RPM started to decrease and it steadily decreased to less than half my original RPM. This on a site that had maintained that same RPM for at least 3 years.
At this point I stopped being lazy and made the changes to the site to be able to incorporate the 160x600 banner. However that was only about a week ago and there has been no dramatic change to RPM. It is just as bad as ever.
I have 3 questions:
1) Is 1 week long enough to know if the changes would make a difference. (I suspect not)
2) Has anyone else had similar experience? "ken_b" has already replied in the other thread mentioned above saying he had something similar happen.
3) If anyone has had a similar experience and recovered what did they do?
personally if I don't recover I will have to go back to building up my email list from this site. Which I am happy to do as I do it with other sites. Only it is quite a bit more effort.
