Welcome to WebmasterWorld Guest from 188.8.131.52
The only difference to the site is that we had a design change and it did affect our click rate. But that is about it.
What I don't understand is if they track clicks by IP address why do they not just exclude them and not charge for the click. I can and do the same when needs be. It isn't hard to do.
If a visitor click on 40 ads, so be it. Google could also limit the amount of clicks a certain person could have. That wouldn't be hard to do either.
I did email them and hope to hear back real soon. My log files alone can't tell me enough unless I know where the "fraud clicks came from. Clicking on an ad does not show up. I did request them to clarify and give me more info so I can find out what the problem is.
If you don't maintain a good click rate for Adwords. What keeps an advertisier (i have experienced them) from creating an add with a low click rate so that more impressions are served. This practice is bad for a website serving the ad (especially a pay per click campaign) it is a waste of time, money, advertising space, and bandwidth.
Having my website reviewed probably was justifiable (although I still don't know the reason), I just hated the secrecy about it. My company's integrity was on the line and I was left to worry about the potential revenue that was at stake also.
We maintain a great click rate so that isn't the problem, I think it was the huge increase in the click percentage in which we still maintain (wasn't a click percentage spike).
I am just glad the worrying is over. It took about 24 hours to resolve in which I am happy. I was worried that it would take longer. I will contact Google and thank them for the speedy review.
Thanks for the help everyone!
