How to audit Performance Max campaign health: forensic guide
(Step-by-step diagnostic framework to uncover hidden bot waste and placement leakage)
If your session recordings in Clarity or Hotjar show PMax clicks bouncing in seconds, cursor moving like a bot, or submitting fake leads, it’s bots clicking your ads. When Smart Bidding runs out of Google.com searchers, it automatically diverts your budget into third-party Search Partner sites and mobile apps, where up to 70% of placements use automated bots for click-revenue arbitrage and draining your budget on traffic that can never convert.
Auditing a Performance Max campaign requires looking far beyond the surface-level metrics displayed on the Google Ads overview screen. High reported CTRs and low cost-per-click numbers often mask critical campaign health issues, such as heavy Search Partner leakage, unmonitored mobile app placements, and high invalid interaction rates. A comprehensive forensic audit examines real on-site telemetry, GCLID authenticity, and conversion validity.

Disproportionate impression volume on unvetted mobile apps
When reviewing Placement Reports, if more than 20% of impressions appear on mobile games, flashlight utilities, or foreign domain portals, your campaign is suffering from inventory dumping.
Severe divergence between reported conversions and sales pipeline
If Google Ads reports hundreds of monthly conversions but your CRM shows stagnant qualified pipeline and sales reps complain of spam leads, your conversion pixel is severely poisoned.
Elevated bounce rates with sub-two-second session durations
Examine Google Analytics 4 engagement times. Inbound ad clicks with session durations under 2.0 seconds and zero scroll depth confirm automated botnet execution.

How BotRefund restores your Performance Max ROI
Deterministic forensic detection on-site combined with certified billing recovery from Google Ads.
83% of our Google refund disputes are approved
Marketers frequently post on Reddit that Google Ads customer support refuses to issue refunds for junk traffic. That is because advertisers submit generic dispute tickets stating "we want our money back from bad sites."
Google billing investigators dismiss subjective placement complaints. However, when BotRefund submits cryptographic TLS JA4 handshakes, automated Chrome DevTools hooks, and verified GCLID microsecond logs proving non-human execution, investigators must approve credits under official Google Policy 11182074.
99% forensic accuracy without relying on useless IP blocklists
Traditional click fraud software tries to block IP addresses. But Google doesn't allow IP exclusions in Performance Max campaigns, and modern bot syndicates rotate through millions of residential mobile IP proxies anyway.
BotRefund operates inside the client browser. We evaluate 180+ behavioral and cryptographic signals—including sub-millisecond mouse tremor entropy, CDP automation hooks, WebGL shaders, and keypress timing—instantly isolating automated form scripts without blocking real human prospects.
Real-time pixel suppression stops the bot feedback loop
When automated bots hit your site from junk websites, any incidental trigger or micro-conversion will corrupt your Smart Bidding model. If Google registers a success signal, it will double down on buying more clicks from that exact publisher network.
BotRefund detects synthetic telemetry in under 50ms and silently suppresses the Google Ads conversion pixel. The spam submission never registers with Google's machine learning, protecting your Smart Bidding model and driving down your true Customer Acquisition Cost.
Zero CAPTCHA friction for your high-value human buyers
Putting annoying CAPTCHA checkboxes or puzzle challenges on your landing page destroys legitimate conversion rates. Real executives and buyers will bounce immediately, while automated botnets solve CAPTCHAs in seconds using automated solving services.
BotRefund operates entirely in the background. Real prospects experience a completely frictionless, fast-loading form submission, while automated scraping bots are cataloged and queued for billing recovery.
