Link Whisper
Link Whisper is a WordPress plugin that scans a site's existing posts and pages, then suggests (or automatically inserts) internal links between them using its own built-in matching engine — no external AI account is required, though an optional OpenAI connection can sharpen suggestions. It also finds orphaned pages, checks for broken links, and scores a site's overall internal-linking health.
Link Whisper's core is a WordPress plugin that scans a site's own posts and matches shared text to suggest links, using its own built-in engine rather than a paid AI or data API by default — genuinely buildable by an AI coding tool, though its orphan-page finder, broken-link checker, and polished one-click dashboard are more ongoing plugin engineering than a weekend covers.
What you lose building it yourself
- ✕Orphan-page finder and broken-link checker in one dashboard
- ✕One-click accept/reject workflow across every post, not a script you re-run by hand
- ✕Google Search Console integration and a link-health score built in
- ✕Ongoing plugin updates as WordPress editors and themes change
Why people still pay
The subscription buys a polished one-click workflow refined across 50,000+ sites' worth of edge cases, plus the orphan-page finder, broken-link checker, and URL changer bundled in — not a single matching feature you'd have to build and maintain yourself.
BUILD YOUR OWN · WEEKEND-PLUS SCOPE
A basic version — scan a WordPress site's own posts, match shared keywords between them, and suggest (or auto-insert) internal links from an admin screen — is realistic for an AI coding tool to build as a plugin over a few sessions. Matching Link Whisper's orphan-page finder, broken-link checker, URL changer, and polished one-click workflow across every editor takes more ongoing plugin engineering than a single script.
StackWordPress Plugin Boilerplate (PHP) for hooks and an admin dashboard · WP_Query to pull every published post's content · a keyword-overlap matching function (no external API needed) to score link candidates between posts · direct content filtering to insert the chosen link on approval.
Build a WordPress plugin in PHP that, from an admin dashboard page, pulls the text of every published post and page via WP_Query, and for each pair of posts computes a simple keyword-overlap score (shared significant words, ignoring common stopwords). List, for each post, its top 3 candidate link targets by overlap score, with a suggested anchor (the highest-scoring shared phrase) and a one-click button that wraps a link around the first matching occurrence of that phrase in the source post's content. Also flag any published post that appears zero times as a link target across the whole site as "orphaned." Use plain PHP and WordPress's own database functions only — no external AI or paid API.
QUESTIONS
Does Link Whisper require an OpenAI account to work?
No — its core suggestion engine is built in and works without any external AI key; connecting an OpenAI key is optional and only sharpens suggestions.
Is there a free version?
No — the cheapest plan is $8/month billed annually for one site. A couple of separate free single-purpose tools exist on the marketing site, but they aren't the plugin itself.
Does it work with any WordPress theme or page builder?
The vendor states it works with Gutenberg, Classic Editor, Elementor, Divi, and Beaver Builder, independent of the site's theme.
