How to Tell if a Website Uses WordPress
Identifying whether a website was built with WordPress 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 10 WordPress-specific signals, and returns a verdict with a confidence score.
You might want to detect WordPress 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 WordPress?
WordPress is an open-source content management system powering everything from personal blogs to large-scale enterprise websites, making it the most widely deployed CMS on the web and a primary target for accurate fingerprinting. AIWebsiteDetector.com identifies WordPress installations using a layered set of technical signals, including 3 distinct script patterns, 2 HTML structural patterns, 2 HTTP response headers, 2 meta tag patterns, and 1 CDN domain reference — collectively providing high-confidence detection across both default and heavily customized deployments. These signals typically manifest as characteristic markup in page source, identifiable request headers returned by the server, and script references tied to WordPress core or its content delivery infrastructure. Because WordPress supports thousands of themes and plugins that can obscure surface-level indicators, the multi-signal approach ensures reliable identification even when administrators attempt to minimize the platform's visible footprint. WordPress itself is free and open-source, but hosting costs vary widely — from shared environments to managed WordPress hosting — meaning the same CMS signature can appear across dramatically different infrastructure setups, a nuance the detection engine accounts for when evaluating header and CDN patterns.
It is primarily used for content-driven websites, blogs, news sites, documentation, and publishing platforms.

Our detection engine checks 10 unique WordPress fingerprints. Here are the most reliable signals:
CDN Domain
Assets (images, scripts, fonts) are loaded from WordPress-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
wp-content/uploadsJavaScript / Script Files
WordPress loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
wp-contentwp-includeswp-jsonHTTP Response Headers
WordPress-hosted sites respond with specific HTTP headers that identify the platform or infrastructure. These are visible in DevTools → Network tab.
x-powered-byx-pingbackHTML Attributes & Class Names
WordPress injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.
wp-block-wp-Meta Tags
Some WordPress sites include a generator meta tag or other platform-specific meta elements in the document head.

Method 1 — View Page Source
- Open the website in your browser
- Press
Ctrl+U(Windows) orCmd+Option+U(Mac) - Search (
Ctrl+F) forwordpressorwordpress - If found in script src, class names, or meta tags — it's likely WordPress
Method 2 — Browser DevTools Network Tab
- Press
F12to open DevTools - Click the Network tab and reload the page
- Filter by

How Our WordPress 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 10 WordPress-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

Get started with WordPressFrequently Asked Questions
How can I tell if a website was built with WordPress?
The most reliable ways to detect WordPress are: (1) open DevTools → Network tab and look for requests to WordPress-specific CDN domains, (2) view page source and search for WordPress-specific class names or data attributes, (3) use our free scanner — we check 10 detection signals automatically and return a confidence score.
Is your WordPress detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for WordPress fingerprints immediately. No account required, no limits on scans.
How accurate is the WordPress detection?
We check 10 unique WordPress 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 WordPress 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.
