WordPress internal linking, done right

See your internal links. Fix the gaps. Undo anything.

Relinka maps how your posts connect, scores your internal-link health, and finds the broken and orphaned pages quietly dragging your SEO down. Then it suggests relevant links — each with a plain-English reason and an anchor taken from your own text — that you apply, or undo, in one click.

Built for bloggers, content teams, and small agencies who care about internal linking.

Blog posts connecting into a tidy linked cluster, illustrating how Relinka maps internal links

Internal linking is one of the most overlooked levers in on-page SEO

Internal links tell Google which pages matter — yet doing it by hand is slow and most tools leave you guessing. Orphaned pages pile up, link equity stays trapped, and readers miss related content. Relinka shows you exactly where the gaps are — and fixes them safely.

From scattered, disconnected pages to a tidy connected cluster

See the whole picture

A link-health score, inbound/outbound counts, a keyword cluster graph, and orphan + broken-link reports — so you know what to fix and why.

Safe by design

Suggest → approve → one-click undo, with a full before/after snapshot. Nothing changes without you. It never invents links or anchors.

Free, no key, no lock-in

Everything runs on your own server — no account, no API key, nothing sent off-site. Works on any theme, Gutenberg or Classic.

Watch a link land — then undo it

Relinka suggests a related-article link with a one-sentence reason, places it at a natural spot, and lets you revert in one click. Toggle below to see the change.

Cats sleep more as they age — it's one of the clearest signs of getting older.

If you notice several of these changes together, it's worth planning for senior care.

Every suggestion comes with a reason

No black box. Relinka tells you why a link belongs, takes the anchor word-for-word from your text, and keeps a snapshot so any change is reversible. It places links at natural spots — never splitting a list or a lead-in.

Know your link health at a glance

A single 0–100 score, calculated from your own site — orphaned posts, missing outbound links, and broken links — plus a keyword cluster graph that maps how your topics connect (so you can spot content silos).

For sites linking at scale

Free fixes today's gaps. Pro keeps them closed — automatically.

You won't need Pro on day one. But once you're publishing often or running several sites, doing it by hand becomes the bottleneck. Pro is the same plugin, with the manual work taken off your plate.

Auto-link on publish

New posts link themselves

Every post you publish gets relevant internal links the moment it goes live — so you never re-audit the whole site again.

Bulk apply

Approve in one pass

Review and apply dozens of suggestions across the whole site at once, instead of one click at a time.

AI / semantic

Links by meaning

Finds related posts by what they're about, not just shared keywords — surfacing relevant links a keyword match misses.

A quick gut-check: if you publish ~8 posts a month, auto-linking saves roughly 2–3 hours of manual interlinking every month. Pro tends to pay for itself in the first week — and the free plugin keeps working untouched whether you upgrade or not.

Questions

Does it need an account or API key?
No. The free plugin is fully functional with no account and no API key — everything runs on your own server.
Will it change my content automatically?
No. Nothing is applied until you approve it, and every applied link can be undone with a one-click revert.
Does it make up links or anchors?
No. It only links to pages that already exist on your site, and every anchor is taken word-for-word from your content.
What data leaves my site?
Nothing. The free plugin doesn't send your content anywhere and doesn't phone home.
What does Pro add?
Pro (a separate add-on from this site) adds AI-assisted suggestions, bulk apply, and auto-linking on publish. The WordPress.org plugin stays free and fully functional on its own.
Free is complete — so why would I pay for Pro?
You don't have to. Free does everything you need to audit and fix internal links by hand. Pro is for scale: it links new posts automatically as you publish, applies suggestions in bulk, and ranks them by meaning with AI. If you publish often or run several sites, Pro turns internal linking from a recurring chore into something you stop thinking about.
