Which analytics tools are actually blocked?
The live block rate of each third-party provider, measured directly across engaged visitors. Vendor-neutral: we measure what's blocked, we don't sell you a replacement.
- 46.7%
Meta Pixel
The Meta Pixel powers Facebook and Instagram ad attribution. When it is blocked, conversions go unreported and ad optimization degrades.
- 40%
Google Analytics 4
Google Analytics 4 is Google's web and app analytics. It is one of the most aggressively blocked endpoints on the web.
- 39.6%
Mixpanel
Mixpanel is an event-analytics platform. Blocked users are invisible to its funnels and cohorts.
- 38.2%
Hotjar
Hotjar records heatmaps and session replays. Blocked sessions never appear in your recordings.
- 35.5%
Segment
Segment is a customer-data pipeline that fans events out to other tools. A block at the source starves everything downstream.
- 35.1%
Amplitude
Amplitude is a product-analytics platform. Blocked clients drop out of every behavioral report.
- 26.3%
Optimizely
Optimizely runs A/B tests and feature experiments. When its CDN is blocked, experiment assignment and conversion tracking silently stop.
- 24.7%
Google Tag Manager
Google Tag Manager loads your other tags. When GTM itself is blocked, every tag it manages goes dark at once.
- 20%
PostHog
PostHog is a product-analytics and session-recording platform. Blocked users send no events, so funnels and retention undercount.
- 9.9%
Intercom
Intercom powers in-app chat and messaging. A blocked widget means those users can't reach support through it.
