Google Ads smart bidding relies on click and conversion data. But if fraud is present, the algorithm gets trained on false signals.
What happens when fraud enters the system:
- Google sees bots as users;
- bids increase for low-quality audiences;
- the model optimizes for fake conversions;
- budget burns fast, results decline.
Warning signs:
- sudden CPC spikes;
- high CTR, zero conversions;
- unfamiliar locations/devices;
- unstable results after enabling Smart Bidding.
How to protect smart bidding:
- Filter fraud before it reaches Google Ads.
- Use AntiClick as an external fraud shield.
- Audit your traffic sources and conversion quality.
- Pause Smart Bidding if fraud spikes are detected.
