Stop Paying for Fake Clicks on Google Ads
StopBots detects and blocks click fraud in real-time using 16 advanced detection engines. Protect your ad budget with automated, multi-layered analysis.
Your Ads Are Under Attack
Industry research suggests a significant portion of web traffic comes from bots. Every fake click drains your budget and corrupts your data.
Wasted Ad Budget
Competitors and bots click your ads — you pay for every click. Without protection, fraudulent clicks can consume a significant portion of your ad spend.
Skewed Analytics
Fake traffic corrupts your campaign data. You end up optimizing for bots instead of real customers, making poor decisions based on unreliable metrics.
Go Beyond Built-in Protection
Google's Invalid Clicks filter is a great start. StopBots adds 16 specialized detection layers on top to catch what slips through.
Three Steps to Protect Your Ads
Set up in minutes. Just add one script tag to your site.
Connect
Add a lightweight tracking script to your site. Loads asynchronously — zero impact on page speed.
Detect
Our 16 detection engines analyze every click in real-time. Browser fingerprinting, TLS analysis, behavioral patterns, and more.
Block
Fraudulent IPs are automatically added to your Google Ads IP exclusion list via the official Google Ads API. CIDR /24 blocking — 256 IPs per slot.
StopBots connects to your Google Ads account via the official Google Ads API to read campaign data and automatically manage IP exclusion lists. You authorize access through Google OAuth — revoke anytime.
16 Detection Engines
Each click is analyzed by multiple detection engines simultaneously.
Browser Fingerprinting
30+ browser signals — canvas, WebGL, audio context, fonts, navigator properties. Detects spoofing and inconsistencies.
TLS Fingerprinting (JA4+)
Network-level detection JavaScript can't spoof. 163 known signatures identify headless browsers and automation tools.
HTTP/2 Fingerprinting
Analyzes HTTP/2 SETTINGS frames and header order. Detects curl, httpx, Go clients, and headless browsers at the protocol level.
IP Intelligence
4-level cache: memory, Redis, local threat lists, IPQS API. Identifies datacenters, VPNs, proxies, and Tor exit nodes.
Behavioral Analysis
Mouse movements, scroll patterns, click timing, touch gestures. Device-aware scoring — different models for mobile and desktop.
Event Trust Validation
Validates physical realism of user interactions — timing correlations, mouse physics, keyboard biometrics, event sequences.
Frequency Analysis
Tracks repeat visits by fingerprint and IP within 24h windows. CGNAT-aware — won't flag shared mobile carrier IPs.
Geo Analysis
Detects timezone/country mismatches between browser locale and IP geolocation. Flags traffic from high-risk regions.
Environment Detection
Cross-validates GPU renderer, platform strings, and automation artifacts. Catches headless Chrome, Puppeteer, and Playwright.
Cross-Client Reputation
Global IP reputation from all StopBots clients. Network effect — a bot blocked on one site is flagged across all sites.
ML Scoring Engine
LightGBM model trained on 42 features with 5-fold cross-validation. Shadow A/B testing and weekly retraining.
PoW Challenge System
Server-issued SHA-256 proof-of-work challenge. Bots that skip it get an automatic 0.9 fraud score. Replay-protected via Redis.
Honeypot Detection
Invisible traps that real users never trigger. Bots that interact with hidden elements are instantly flagged with high confidence.
Campaign Context
Validates Google Ads campaign metadata — gclid parameters, campaign IDs, and ad group consistency. Catches clicks with forged or missing tracking data.
SERP Referrer Validation
Verifies search engine referrer authenticity. Distinguishes real Google Search clicks from direct URL visits and forged referrers.
Session Depth Analysis
Tracks visitor session lifecycle — page views, time on site, interaction depth. Real users browse; bots bounce after one click.
All engines run simultaneously on every click. Average response time: <50ms. Zero impact on your site speed.
Real-Time Fraud Monitoring
