My core sites run at about 5% CTR and I have some niche site which have months of averages up to 30%.
A few moments a go I received a nice click dump and noticed that there were several channels with much higher CTR's than normally experienced.
Strangely I only responded to a similar post earlier today and I felt that the red flag was raised at about 25%.
Several of these channels today have averaged between 30-100%.
My guess is that the Adsense team have seen the activity, checked it out, and have now credited me with the valid earnings.
If this is correct then do we actually have to worry about excessive clicks since the team are monitoring it all the time thus our click abuse paranoia is just that?
If this were to be true then would that mean none of us would actually know how many clicks, valid+invalid, we are really getting?
What's your take on it?
Do the click counters really work in your opinion?
My faith's in G at this point since I am happy with the program at the moment however it would be really interesting to know how many invalid clicks there are per week/month?
