What percentage of Performance Max clicks are bots? (Real data)
(Forensic benchmarks across 1.5 million daily clicks reveal true invalid traffic rates)
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.
Google Ads publicly claims that invalid traffic accounts for a negligible fraction of ad spend and that automated filters catch the vast majority of bad clicks. However, independent forensic analysis across more than 1.5 million daily Google ad clicks tells a radically different story. Across active Performance Max campaigns, true invalid click rates consistently range between 18% and 28%—with certain high-CPC lead generation verticals exceeding 40%.

Campaign vertical and Cost Per Click (CPC) valuation
Click fraud syndicates target high-value verticals (legal, financial services, enterprise SaaS, insurance) where clearing bids exceed $20 per click, delivering maximum payout per fraudulent interaction.
Search Partner and Display Network budget allocation
Campaigns with higher budget percentages diverted into syndicated Search Partner websites and mobile app placements experience 3x higher bot rates than pure Search campaigns.
Sophisticated residential proxy botnet evolution
Modern botnets run headless Chrome across residential mobile IP networks with randomized user agents and behavioral timing, easily bypassing Google’s legacy server-side filters.
How to calculate your account’s true bot percentage
Follow these direct in-account steps to audit your campaigns, eliminate placement waste, and restore optimal conversion efficiency.
Check Google’s reported invalid click rate
Review Google Ads Campaigns → Columns → check "Invalid clicks" and "Invalid click rate". Note the baseline percentage Google admits to catching.
Calculate zero-second GA4 bounce discrepancies
Examine sessions from Google Ads where session duration is 0 seconds and user engagement rate is under 5%. This reveals traffic that bounced before rendering.

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.
