How to Check if a Website Uses WordPress

Five reliable ways to tell if any website is built on WordPress — from the page source to REST API endpoints.

Want to know if a site runs WordPress? Here are the most reliable signals.

1. Look at the page source

View source and search for `/wp-content/`, `/wp-includes/` or `wp-json`. If you see these paths, it's almost certainly WordPress.

2. Check the generator meta tag

Many WordPress sites include `<meta name="generator" content="WordPress 6.x">` in the HTML head.

3. Try the REST API

Visit `/wp-json/`. If it returns JSON, the site uses WordPress.

4. Check /wp-login.php

If `/wp-login.php` shows a login screen, that's a strong WordPress signal.

5. Use an automated detector

WPDoctor detects WordPress instantly and also identifies the theme, page builder (Elementor, Divi), WooCommerce, and SEO plugins like Rank Math or Yoast — all from the outside.
