What is the Ad Blocker Checker?

The Ad Blocker Checker is a free tool that analyzes your website to detect which analytics and marketing tools are being blocked by ad blockers, privacy filters, and tracking prevention technologies. It provides instant insights into how these blockers affect your data collection.

How does the checker work?

Our checker visits your website and identifies all analytics and marketing tools (like Google Analytics, Meta Pixel, etc.) that are loaded. We then cross-reference these tools against popular ad blocker filter lists to determine which requests would be blocked for users with ad blockers or privacy settings enabled.

What tools can be detected?

We can detect most popular analytics and marketing tools including:

  • Analytics: Google Analytics, Matomo, Mixpanel, Amplitude, Heap
  • Tag Managers: Google Tag Manager, Segment
  • Marketing Pixels: Meta Pixel, TikTok Pixel, LinkedIn Insights, Twitter Pixel
  • Session Recording: Hotjar, FullStory, Microsoft Clarity
  • And many more tools commonly used for tracking and analytics.

Is my data safe?

Yes, absolutely. We only collect publicly accessible information from your website - the same data that any visitor could see. We don't store any sensitive information, user data, or analytics results. The check is performed in real-time and results are not permanently stored.
