How to run Performance Max without bot fraud: best practices guide
(The complete technical playbook to shield your budget and maximize real pipeline)
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.
Running Performance Max successfully requires treating it like an autonomous vehicle: you cannot leave it on full autopilot without guardrails. Default campaign settings allow Google to expand your URLs indiscriminately, bid on low-tier mobile game apps, and optimize toward unverified micro-conversions. To run PMax profitably without click fraud, you must implement strict account-level controls, brand exclusions, and real-time client-side pixel shielding.

Strict account-level placement exclusion lists
While PMax disables campaign-level placement exclusions, you can upload up to 65,000 domains and mobile apps to an Account-Level Placement Exclusion List in Google Ads to block known bot farms.
Turn off final URL expansion and brand cannibalization
Disabling Final URL Expansion prevents Google from sending traffic to random pages on your site. Implementing Brand Exclusion Lists ensures PMax doesn’t inflate metrics by bidding on your own trademark.
Client-side pixel suppression stops bot feedback loops
Even with placement lists, new bot domains emerge daily. Real-time client-side telemetry detects automated browsers in 50ms and blocks Google conversion pixels from registering fake leads.
How to audit your Performance Max settings for bot vulnerabilities
Follow these direct in-account steps to audit your campaigns, eliminate placement waste, and restore optimal conversion efficiency.
Check Final URL Expansion status
Go to Campaign Settings → URL Expansion. Toggle URL expansion to "Off" to ensure ads only land on designated, monitored landing pages.
Verify Account-Level Placement Exclusions
Navigate to Tools & Settings → Placement Exclusion Lists. Ensure you have added common mobile app categories (`adsenseformobileapps.com`) and known MFA networks.
Install BotRefund automated conversion protection
Add BotRefund’s tag to your site via GTM. We handle real-time pixel suppression and manage automated 60-day Google refund claims on 100% contingency.
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.
