How to Tell if a Website Uses Blogger
Identifying whether a website was built with Blogger 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 9 Blogger-specific signals, and returns a verdict with a confidence score.
You might want to detect Blogger 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 Blogger?

Our detection engine checks 9 unique Blogger fingerprints. Here are the most reliable signals:
CDN Domain
Assets (images, scripts, fonts) are loaded from Blogger-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
blogger.googleusercontent.comd.bp.blogspot.comJavaScript / Script Files
Blogger loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
blogger.googleusercontent.comwww.blogger.com/staticblogblog.comHTML Attributes & Class Names
Blogger injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

Method 1 — View Page Source
- Open the website in your browser
- Press
Ctrl+U(Windows) orCmd+Option+U(Mac) - Search (
Ctrl+F) forbloggerorblogger - If found in script src, class names, or meta tags — it's likely Blogger
Method 2 — Browser DevTools Network Tab

How Our Blogger 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 9 Blogger-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 Blogger?
The most reliable ways to detect Blogger are: (1) open DevTools → Network tab and look for requests to Blogger-specific CDN domains, (2) view page source and search for Blogger-specific class names or data attributes, (3) use our free scanner — we check 9 detection signals automatically and return a confidence score.
Is your Blogger detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Blogger fingerprints immediately. No account required, no limits on scans.
How accurate is the Blogger detection?
We check 9 unique Blogger 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 Blogger 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.
