I display adsense ads on my blog which is hosted by blogger for free of charge. I want to know how can I protect myself from click sabotage if it occurs and how do I know when it occurs? I asked to google same question they replied me. I am copying the part of their reply: .... you can feel free to review your site's traffic logs for suspicious activity and notify us with any findings. This information can help us in resolving any issues, although as we've noted in our Terms and Conditions, Google will use its sole discretion when determining instances of invalid clicks. If you need help logging the traffic on your site, please try these Google search terms: Webmaster resources Website tracking and logging Site traffic analysis .... I still need help logging the traffic on my blogger blog. I also asked the same question to google but I haven't received a reply yet. I have one more question: Since google technology can determine all of invalid clicks and doesn't generate revenue from invalid clicks, do I have to worry about a sabotage and why?
There are few things that come to mind: 1) Do not alienate people (or if you do, try to be anonymous). If you make somebody mad and they know you are a webmaster of certain site, a sabotage is possible. 2) Keep detailed web logs - if Google does contact you, better make sure you have all the data you need to provide to them. 3) Make sure you control all the content on your sites. If you run a forum, make sure it's well moderated. Otherwise, someone can post a "Click on the ads to support this site" and visitors may click excessively. Overall, I don't think you should worry about it too much - you cannot really predict who comes to your site and what they will do. However, if you do receive the dreaded "invalid clicks" email, it's good to be prepared.
