Find every website using a WordPress plugin

Published September 15, 2025 · WordPress · 2 min read

Search wp-content/plugins/<slug> for the plugin's folder name. That path only appears when the plugin actually enqueues an asset, so a match is real — not a mention in a blog post.

A plugin's marketing name almost never appears in a page's HTML. Its folder does. WordPress serves plugin CSS, JS, and images from wp-content/plugins/<slug>/, so the moment a plugin enqueues anything, that path is in the source. Search the path and you skip every review, tutorial, and "10 best plugins" listicle that merely names the plugin — you get sites that actually load it.

Get the folder slug

The slug is the last part of the plugin's WordPress.org URL — wordpress.org/plugins/akismet/ → akismet. For a plugin you can't find there, open one site you know runs it and search its source for wp-content/plugins/. Don't guess from the display name: "WP Rocket" ships as wp-rocket, punctuation gets dropped, and a Pro edition sometimes lives in a different directory than the free one.

Run it

Search the exact path, e.g. wp-content/plugins/woocommerce. In the July 2026 index that footprint is on 4,112,625 sites — the same signal behind the WooCommerce technology page. For scale, the bare WordPress footprint wp-content covers 21,549,150 sites, so the plugin path narrows a fifth-of-the-web population down to the exact installs you want.

Page builders work the same way: wp-content/plugins/elementor finds every site styled with Elementor.

Verify, then export

Open any result to read the full homepage source with the match highlighted — that's how you confirm it's a live install and not a stray reference. When the list looks right, export the domains as CSV from the results toolbar. Viewing source never costs an extra search.

Narrow further

Add a second term to profile the install. "wp-content/plugins/woocommerce" "static.klaviyo.com" gives you WooCommerce stores that also run Klaviyo — a much warmer list than either footprint alone. Or exclude: "wp-content/plugins/elementor" -"wp-content/plugins/woocommerce" for Elementor sites that aren't stores.

Frequently asked questions

Why not just search the plugin's name?

The name shows up in reviews, tutorials, and marketing pages far more often than on sites that run it. The wp-content/plugins/<slug> path only appears when the plugin loads an asset, so it points at real installs.

How do I find a plugin's folder slug?

It's the last segment of its wordpress.org/plugins/<slug>/ URL. For plugins not listed there, open a site you know uses it and search its source for wp-content/plugins/ to read the directory name directly.

Does a match guarantee the plugin is active?

It means the plugin enqueued an asset on that page — effectively active on the homepage. Open the result's full source to confirm the context before you rely on it.
