HrefHub

You changed a URL. Now it is wrong in forty-seven posts and you have no list of which ones.

Broken link plugins tell you what is broken. Search-and-replace plugins swap a string across your database and hope. Neither of them shows you what you actually have. HrefHub is the link inventory : every link on the site, grouped by where it points, with the number of places it appears and what happens when you follow it.

Then it lets you change one of them everywhere, in one action.

What it does

• Lists every link found in post content and Gutenberg blocks, grouped by destination URL
• Shows how many places each URL appears, and which posts they are
• Checks HTTP status and counts the redirect chain, so “three redirects” reads differently from “404”
• Filters by status, internal or external, host, post type, and anchor text
• Changes a URL everywhere it appears, with a confirmation preview first
• One-step undo of the last change
• Bulk action: replace every redirecting URL with its final destination
• CSV export of whatever you are currently looking at

The one that saves an afternoon

Sites accumulate redirects. A link you added three years ago now goes through two or three hops before it lands. Filter to Redirecting , select all, and choose Replace redirects with their final destination . Every one of them is rewritten to point straight at where it already ends up.

What gets scanned

This version reads:

• All public post types, plus reusable blocks — untick any you do not want under HrefHub → Settings
• post_content HTML anchors
• Gutenberg block attributes — button URLs, image links, cover backgrounds and so on

This version does not read links stored by page builders (Elementor), custom field plugins (ACF), navigation menus, widgets, theme options or FSE templates. They are not listed and they are not changed. The admin screen states this too, so you always know what the numbers cover.
