Just got the same form message a couple hours ago. Must take all of 10 seconds to click the send button. My CTR went down to 10% of its former rate. I've put acres around the ads, changed the background color, removed all other ads so no one can say they are being confused with Google's, and moved the 1st ad to the top of the page and the 3rd one to the bottom. The middle of the page is a long list which is the focus of the visitors' attention, but it has a lot of text links, so I wonder if that is the issue, valid or not.
If I try to see things as Google explains it, and if I'm reading it right, I'm trying to fit my experience into it, but it just doesn't make sense. For the purpose of discussion, let's say that they changed their invalid click detection some how and rolled it out from June 29 through July 1st, and a few of us had ads that resulted in invalid clicks. Let's say that one option for them is measure the time between clicking on an ad and the time that they click back to our page. If it's really short, then it's likely a mistake. I can see that taking a few minutes to analyze and then claw back. Obviously, this basic detection method has been implemented for years, but there must be some tweak. Probably some more elaborate behavior formula that generalizes, probably detecting "probable" invalid clicks, instead of "actual". (Intentional and unintentional clicking by owners, bots and enemies would involve different detection methods, but if that were the issue in my case, I should still have some valid clicks.)
I'm going to play their game, it's all we can do right? I've changed the placement of 2 out of the 3, doing all that I can think of to make it impossible to accidently click on an ad. My CTR *has* gone up a little in the last few hours, but not enough to say it's any more than normal variation. I'll try the Enhanced Text Ads opt out, as well. I just realized that I was unaware of all the tabs under Allow & Block.
