Ad Blocker Statistics 2026: Usage Rates by Browser, Industry & Analytics Tool

1. Global Ad Blocker Usage Rate

29.5% of internet users worldwide ran an ad blocker as of Q2 2025 — around 1.77 billion people. Most marketing teams guess lower than reality here, and there's a structural reason why: the visitors an adblocker hides are, by definition, absent from the exact reports you'd use to notice them.

Treat that global number as a starting point rather than a prediction for your own site. It skews hard by country (Indonesia leads at 40.1%, the US sits at 32.5%), by device (desktop well ahead of mobile), and by audience. The industry ranges further down are directional, drawn from those patterns rather than measured directly — a reasonable prior to check your own data against, not a replacement for measuring it.

2. How Each Browser Actually Affects Analytics

"Blocked" gets used loosely, and the distinction underneath it actually matters if you're trying to figure out what your own numbers are missing. Some browsers kill the analytics request outright, so the hit never reaches Google and the session just isn't there. Others let the request through and restrict the cookies instead, so the visit gets counted but misattributed, usually logged as new rather than returning. Two very different failure modes, and they don't look alike in a report.

What that means in practice: outright request blocking comes almost entirely from Brave's default Shields and from users running an extension, not from Firefox or Safari on their default settings, despite how often that gets claimed. Chrome's Manifest V3 migration has since disabled the original uBlock Origin for most Chrome users, pushing them toward the weaker uBlock Origin Lite, while Firefox kept supporting the full version.

3. Ad Blocker Rate by Industry

The global average hides how differently audiences actually behave. Mainstream shoppers browsing a B2C store on mobile Chrome block at a much lower rate than developers opening a SaaS tool from a Brave-equipped laptop.

4. Which Analytics Tools Are Most Affected

Blocking isn't uniform across tools. The ones built on well-known third-party domains get hit hardest, since their endpoints sit on every major filter list; anything self-hosted or routed first-party gets off comparatively easy.

GTM is the special case worth calling out on its own. Because it acts as a container for every other tag, blocking it takes GA4, Facebook Pixel, and everything else it fires down with it in one move — even for tags whose own endpoints were never individually blocklisted.

5. Revenue Impact Estimates

Missing pageview counts are the least of it. The real cost is conversion events — purchases, signups, form fills — happening inside sessions your analytics never saw at all. You still paid the acquisition spend for those visitors; you just can't attribute or optimize around what they did.

Zoom out and ad blocking is estimated to have cost publishers $54 billion in lost ad revenue in 2024 — about 8% of global digital ad spend. For a business that actually depends on its analytics, the cost goes further than lost ad revenue: broken attribution makes your best channels look worse than they really are.

Better than estimating from averages: measure it directly. The scanner loads your page in a browser running uBlock Origin and reports back every tag that got blocked.

6. Is the Trend Growing or Declining?

Usage is climbing, but extension installs aren't really driving it anymore. What's shifted is browser-native blocking becoming the default for hundreds of millions of people who never consciously decided to block anything at all.

Analytics data loss isn't a fringe problem confined to privacy die-hards anymore. It's mainstream and structural, and it compounds every year that browsers keep making privacy-by-default the norm rather than the exception.
