Google is working hard to protect you from advertising fraud that uses automated detection, manual review, and investigations. TrafficGuard provides an added protection over Google's effort of reducing ad fraud. And even if click fraud is detected by Google, it's rather reactive than TrafficGuard's PPC Protection's proactive approach. Google will only refund you with credits after fraud has already taken place. This means your PPC ads will stop displaying during the campaign as your budget has been exhausted.
With TrafficGuard's PPC Protection, you don't have to wait until Google refunds your advertising budget back. You also stop wasting your time manually blacklisting IPs since TrafficGuard automatically updates your campaign level IP blacklists in Google Ads. Now you can focus efforts on optimisation and growth of your business.
