Re: Hundreds/Thousands of invalid clicks from click fraud
Hi Mike and welcome to the community.
Google has sophisticated monitoring and detection systems to identify, report, and act on invalid clicks or impressions when our system finds they may have occurred.
However, if you're concerned about activity that seems suspicious, answer the questions on this form to find information on click behavior, filtering, and reporting.
If you are still having problems, I'll be happy to refer this post to our support team in order to investigate further.
Hope that helps.
