How to find out what WordPress theme a site is using

Manually checking source code is tedious. Our tool scans the HTML for common patterns like "/wp-content/themes/" or specific generator meta tags to identify the exact theme name and version active on any WordPress site.

Why analyzing competitor tech stacks helps your SEO

Success leaves clues. If a competitor is ranking high with lightning-fast page speeds, they might be using a lightweight theme like GeneratePress or a specific caching plugin like WP Rocket. Detecting their stack allows you to replicate their technical foundation.
