How to deal with click fraud?

Question

Google Ads

Colleagues, please tell me how to deal with click fraud? Over the past 30 days, the share of invalid clicks is 73%. Advertising on search with very high competition. What are the solutions, for example, in PHP. Or is it better to leave everything to the system?

Answer 1

so AdWords still can’t force you to return more
you can look at https://clickfrog.ru/ some
if there is a lot of traffic - it’s more useful to have your own ML algorithms trained on such traffic

Answer 2

There is a solution, put your own statistics that writes all the logs including ip addresses and send reports to google manually.
