How to Fix Analytics Blocked by Ad Blockers
Filter lists like EasyPrivacy and uBlock Origin block requests to google-analytics.com, googletagmanager.com, and connect.facebook.net the moment they leave the browser — silently, with no error visible to you.
This page explains exactly what gets blocked, why those domains are on every filter list, and how a first-party proxy recovers the signals without rerouting all your traffic or requiring server-side infrastructure.
The scale of this problem is measurable and consistent. Brave browser ships with Shields enabled by default — 100% of Brave users block analytics. Firefox with Enhanced Tracking Protection (ETP) is on by default for all new installs — approximately 85% of analytics requests are blocked under Strict mode. Chrome users with uBlock Origin block around 42% of tracking requests. Across a typical B2B or tech-focused site, this adds up to 25–40% of sessions generating zero analytics data.

What Exactly Gets Blocked — and What Doesn't
Adblockers operate at the network request level, not the JavaScript level. They don't disable JavaScript — they intercept HTTP requests before they leave the browser. Your analytics code runs normally; it's the outbound network call that gets dropped.

How Introtrace Recovers Your Blocked Data
Unlike server-side tracking or full proxies, Introtrace only touches signals that adblockers actually block. Everything else goes directly to your analytics provider.
Add One Script Tag
Add a single line of code to your website. No server-side changes, no complex configuration. Works alongside your existing GA4, GTM, and marketing pixels.
Blocked Signals Detected
When an adblock or privacy extension blocks an analytics signal, our lightweight script detects it instantly. Unblocked signals are never touched.
Data Recovered to Your Tools
Blocked signals are routed through our proxy and forwarded to your analytics provider. Your GA4, GTM, Facebook Pixel, and other tools receive the complete data.
Works With Every Analytics Platform
Introtrace recovers blocked signals for all major analytics and marketing platforms. No configuration needed per tool.

Why Adblockers Block Your Analytics
Adblockers don't guess — they match against maintained blocklists that explicitly target analytics and tracking domains. Understanding this is the key to recovering the data.
The Filter Lists
Community-maintained lists like EasyPrivacy, uBlock Origin filters, and Disconnect.me's tracking list contain tens of thousands of patterns targeting known analytics domains. They're updated daily as new tracking endpoints appear.

Extensions aren't the whole picture. Brave, Firefox ETP, Safari ITP, and Edge all ship with tracking protection on by default — no extension required. This means a meaningful share of your audience is blocking analytics at the browser level without ever installing anything.
See the full browser-by-browser breakdownThe key insight is that these filter lists are maintained by large volunteer communities — EasyList's EasyPrivacy list has been maintained since 2009 — and are updated daily. Any analytics vendor that grows large enough to be worth tracking will eventually appear on these lists. This isn't a bug in a specific analytics tool; it's a structural reality of the web's privacy ecosystem. The only durable solution is to move analytics traffic off third-party domains entirely.
Why a First-Party Proxy Recovers the Data
Filter lists match against request domains and URL patterns. When a blocked analytics signal is rerouted through a subdomain of your own site — for example, analytics.yoursite.com — it doesn't match any pattern on any blocklist. The request is indistinguishable from any other first-party API call your site makes.

2-Minute Setup
Add one script tag and you're done. No server-side changes, no DNS configuration on the free plan, no engineering sprint needed.
GDPR & CCPA Compliant
Zero-logging proxy infrastructure. We never store analytics data. Your data flows directly from your visitors to your analytics provider.
Recovers Only Blocked Signals
Unlike full proxies that route all traffic, Introtrace only intervenes when a signal is actually blocked. Lower cost, lower latency, cleaner data.
Accurate Geographic Attribution
Recovered signals preserve the visitor's original location context, so your geographic reports, audience segments, and anti-fraud signals stay accurate. No data quality degradation.
Start Free, Scale as You Grow
20,000 recovered signals per month included free. Paid plans start at $9.99/month with custom domain support for even better recovery rates.
Unlike full reverse-proxy setups that route all your traffic through an intermediary — adding latency and infrastructure cost — Introtrace is selective. It monitors for blocked requests and only acts on those. For a site where 30% of users block analytics, that means 70% of traffic is completely unaffected, going directly from browser to your analytics provider as it always has. There's no single point of failure, no new latency for the majority of your users.
Frequently Asked Questions
What's the fastest way to check if I'm losing analytics data right now?
Open your site in Brave with DevTools' Network tab open, then load the same page in regular Chrome. In Brave, requests to google-analytics.com and googletagmanager.com simply won't appear — no error, no console warning, just silence. That's the gap Introtrace recovers.
How does Introtrace recover blocked analytics data?
Introtrace detects when an analytics signal is blocked by an adblock or privacy extension, then routes only those blocked signals through our proxy to your analytics provider. Unblocked signals go directly to your provider as normal — we never touch them.
Is recovering ad-blocked analytics data legal and GDPR compliant?
Yes. Introtrace operates as a pass-through proxy that does not store any user data. We are fully GDPR and CCPA compliant. The analytics data is forwarded directly to your existing analytics provider with no intermediate storage.
What analytics tools does Introtrace work with?
Introtrace works with all major analytics and marketing platforms including Google Analytics 4 (GA4), Google Tag Manager (GTM), Facebook Pixel, TikTok Pixel, LinkedIn Insight Tag, Mixpanel, Amplitude, Segment, Hotjar, and many more.
How long does it take to set up Introtrace?
Setup takes under 2 minutes. Add a single script tag to your website's head section. No server-side changes required. You can start recovering blocked analytics data immediately.
Does recovering adblocked analytics violate user privacy?
No. The data collected is identical to what analytics tools already collect from users who don't have adblockers. You're recovering signals the user would have sent anyway — the adblock simply prevented the network request. Introtrace does not collect any additional data, does not fingerprint users, and does not store data beyond the proxied request lifetime.
How do I know how much data I'm currently losing to adblockers?
The most direct way: compare your analytics session count against your server logs or CDN request count for the same period. The gap between server-side requests (which adblockers don't affect) and GA4 sessions is approximately your adblock loss. After installing Introtrace, you can see recovered signal volume directly in your dashboard.
Can adblockers detect and block Introtrace?
Introtrace routes signals through your own first-party subdomain (e.g., analytics.yoursite.com). Since this is your own domain, it cannot appear on any third-party blocklist without also blocking your entire website. Filter lists are maintained by communities that would not add first-party domains to their lists.
