Understanding Google Ads invalid activity adjustments on Performance Max
(Why automatic adjustments miss 90% of bot fraud—and how to recover the rest)
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.
If you check your Google Ads monthly billing invoice, you may occasionally notice a small credit line item labeled "Invalid Activity Adjustment." Many advertisers assume Google is actively catching all click fraud and protecting their budget. In reality, Google’s automated system only credits crude, high-velocity botnets that trip basic thresholds—typically amounting to less than 1% to 2% of total spend. Meanwhile, sophisticated residential bots consume 18% to 28% of your budget undetected.
BotRefund detects bot clicks on PMax and gets you refunded by Google
We uncover the 90% of invalid clicks that Google’s automated system overlooked, securing substantial manual billing adjustments under Policy 11182074.

Google’s pre-billing filters only detect basic datacenter scrapers
Google’s automatic adjustments look for primitive bot signatures: known server hostnames (AWS, DigitalOcean), extreme click frequencies, and missing user agents. They miss sophisticated residential bot networks.
Sophisticated bots mimic human behavioral entropy
Modern click fraud syndicates run headless Chrome on real user IP addresses with human-like mouse curves and randomized pause intervals. Google’s real-time ad server cannot detect these without client-side inspection.
Google faces an inherent conflict of interest in traffic auditing
Google earns revenue on every ad click. Aggressively filtering out all borderline bot traffic on Search Partner and Display networks would immediately decrease publisher network revenue.
How to check your historical invalid activity adjustments
Follow these direct in-account steps to verify invalid traffic volumes and determine your refundable ad spend balance.
Open Google Ads Billing Invoices
Go to Tools & Settings → Billing → Documents. Download your last 3 monthly tax invoices or billing statements.
Locate the "Invalid Activity" line item
Review the credits section. Compare the automatic adjustment amount against your total monthly ad spend to determine your current automatic credit rate.

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.
