Syncs your site
Sends your pages, titles, URLs, content, and link graph to HappyLinks, so every recommendation is based on the site you actually have.
The HappyLinks Plugin
WordPress Plugin for Interlinking
HappyLinks figures out which links your site needs. The plugin is what actually places them - syncing your pages and applying approved internal links without you touching code or copy-pasting a thing.
Free to install. Works with any single-site WordPress site.
What it does
HappyLinks thinks. The plugin acts.
The HappyLinks web app reads your content, builds your semantic map, and finds the links worth making. None of that changes your site on its own. The plugin is the connection that turns those recommendations into real, published links - only the ones you approve.
Places internal links
Applies the internal links you approve - and keeps them current when slugs change or pages move.
Prepares for backlinks
Keeps the site connection and link graph ready for the backlink network when it opens later.
Keeps you in control
Nothing publishes until you approve it. Every change is logged, and anything can be rolled back.

Trust
A plugin that respects your site.
You approve every change
The plugin never publishes a link you haven't reviewed. Internal links and site edits wait for your sign-off.
Everything is reversible
Every change the plugin makes is logged with a clear before-and-after. Undo a single link or roll back in bulk.
Lightweight by design
The plugin syncs and applies changes, then gets out of the way. It's not a page builder and it won't slow down your site.
Get the plugin. Put HappyLinks to work.
It's free, it installs in minutes, and the internal-link tools are free to use from day one.
