Invalid clicks: how to request a Google refund and what anti-fraud adds beyond it

Sometimes Google Ads shows a line about invalid traffic and an automatic credit. A Tashkent business owner celebrates: «Google refunded me — so I'm protected». Partly true. A refund is after the fact for a narrow click class. It does not retrain the algorithm, clean lists, or stop the next bot from hitting your form. Here's what Google filters itself, how to ask for credit, what refunds don't cover — and why you need a site-side anti-fraud layer.

Summary
Invalid clicks and Google credits are useful but partial: they cover a narrow traffic class after the fact and do not fix algorithm training. Site anti-fraud, IP exclusions, and clean conversions work upstream and give control you don't get from a «Report» button. Start with loss assessment in click fraud, review attacks in the bots article, and build the layer from the anti-fraud guide. Need it wired to your account — Google Ads setup with UZNEO.
