How to Tell if a Website Uses Google Analytics
Identifying whether a website was built with Google Analytics used to require technical expertise — inspecting source code, tracing network requests in DevTools, and knowing which patterns to look for. Our free scanner automates all of that: it fetches the page, analyzes 4 Google Analytics-specific signals, and returns a verdict with a confidence score.
You might want to detect Google Analytics for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.
What is Google Analytics?
Google Analytics is a web analytics platform developed by Google, widely used by businesses, publishers, and developers of all sizes to track visitor behavior, measure traffic sources, and analyze site performance. AIWebsiteDetector.com identifies Google Analytics deployments through a combination of two distinct script patterns and two HTML patterns, typically including references to Google's analytics JavaScript libraries and associated tracking markup embedded in page source code. These signals are reliable indicators because Google Analytics implementations follow consistent structural conventions whether the tracking code is loaded via gtag.js, analytics.js, or through a tag manager integration. The platform is free to use at its standard tier, with Google Analytics 4 (GA4) representing the current generation following the deprecation of Universal Analytics, a transition that introduced new script signatures our detection engine accounts for. Detection confidence is high across virtually all site categories, as Google Analytics remains one of the most ubiquitous third-party scripts on the web, found on everything from small personal blogs to large enterprise properties.
It is primarily used for business websites, portfolios, landing pages, and personal sites without coding knowledge.

Our detection engine checks 4 unique Google Analytics fingerprints. Here are the most reliable signals:
JavaScript / Script Files
Google Analytics loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.

Google Analytics injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

How Our Google Analytics Detector Works
When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 4 Google Analytics-specific fingerprints:
Script analysis
We scan all loaded JavaScript files for known CDN paths and runtime names
CDN domain matching
We cross-reference every asset request against known platform CDNs
HTML pattern scanning
We search the DOM for platform-specific class names and data attributes
Header inspection
We read HTTP response headers that identify the server or platform
Meta tag extraction
We check generator and other meta tags in the document head
Confidence scoring
We weight each matched signal and normalize to a 0–99% score

How can I tell if a website was built with Google Analytics?
The most reliable ways to detect Google Analytics are: (1) open DevTools → Network tab and look for requests to Google Analytics-specific CDN domains, (2) view page source and search for Google Analytics-specific class names or data attributes, (3) use our free scanner — we check 4 detection signals automatically and return a confidence score.
Is your Google Analytics detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Google Analytics fingerprints immediately. No account required, no limits on scans.
How accurate is the Google Analytics detection?
We check 4 unique Google Analytics fingerprint signals across HTML, JavaScript, CDN domains, meta tags, and HTTP headers. Our confidence score reflects how many signals matched — a score above 70% is a strong indicator. We cap accuracy at 99% to reflect that all fingerprint-based detection is probabilistic.
Can Google Analytics sites be detected if they use a custom domain?
Yes. Custom domains don't hide the underlying platform. The JavaScript files, CDN requests, HTML attributes, and server headers all remain identifiable regardless of the domain name used. Our scanner fetches the page directly and analyzes its technical composition.
