What separates the tools is the depth of detection, the ad platforms they cover and how they integrate. Some focus narrowly on Google Ads, others span Meta, TikTok and programmatic networks. Deployment ranges from simple JavaScript tags to direct API connections, and the best options automate refund claims or adjust bids without manual input.
