Description
Internal links help readers and search engines find your best content, but adding them by hand is tedious. Indigothorn Internal Links reads your posts and, while you edit, suggests which other posts to link to and which phrase already in your text to use as the link. One click inserts the link; your sentences are never rewritten.
- Link suggestions panel in the block editor, working on unsaved changes too.
- Anchor text from your own words: only phrases that appear in your text and match the title of the target post.
- Orphaned posts report (Tools Link Assistant): posts no other post links to, and for each one the posts that could link to it, with the phrase to use.
- Classic editor: the same suggestions in a “Link suggestions” box next to the editor, with Insert link and Dismiss, in the Visual and Text tabs.
- Link counts: inbound and outbound internal links for every post, with a summary (posts without inbound links, posts that link nowhere), search and sorting. Also
wp indigothorn-internal-links counts. - Dismiss a suggestion you do not want: that post is never proposed for that link again, in the editor or the report, until you restore it.
- Insert links from the report: tick the posts that should link to an orphan, check the before/after preview and insert all links at once, without opening each post. Every change is saved as a revision.
- Works out of the box: no keywords to configure, no AI service, nothing leaves your site.
- WP-CLI:
wp indigothorn-internal-links index,wp indigothorn-internal-links orphans.
Why this one
Most free internal-linking plugins make you type keywords by hand and then link them automatically everywhere. Paid tools such as Link Whisper read your content instead. Indigothorn Internal Links does that for free: it reads your posts, suggests where to link, and lets you decide.
- Relevant: in our tests every suggestion pointed to a post on the same topic (477 suggestions on an English site, 145 on a site mixing Polish, English and German).
- Natural anchors: a single word is only used when it is one of the distinctive words of the target title, so you will not get links on words like “first” or “guide”.
- Fast on big sites: with 10,000 posts, suggestions appear in about 70 ms; the index is built in the background (about 6 ms per post).
Screenshots
Installation
- Install and activate the plugin. Your posts are indexed in the background.

- See Tools Link Assistant for orphaned posts and the posts that could link to them.
FAQ
-
Does it add links automatically?
-
No. You choose every link. The plugin only suggests and, when you click “Insert link”, wraps the suggested phrase in a link.
-
Can I add links without opening every post?
-
Yes. In Tools Link Assistant, open “Find posts that could link here” for an orphaned post, tick the posts you want, click “Preview selected links” and check the before/after text, then “Insert links”. Only the highlighted phrase becomes a link and each post gets a new revision, so you can undo it from the post’s revisions. A post that was edited after the preview, or that already links to the target, is skipped.
-
Does it work with the classic editor?
-
Yes. Posts edited with the classic editor get a “Link suggestions” box in the sidebar of the edit screen. It works in both the Visual and the Text tab; shortcodes, existing links and HTML tags are left alone. In the block editor the suggestions stay in the sidebar panel.
-
How do I see which posts get few internal links?
-
Open Tools Link Assistant Link counts. Every indexed post is listed with the number of other published posts linking to it (inbound) and the number it links to (outbound). Sort by inbound to find weakly linked posts, then use “Find posts that could link here”. From the command line:
wp indigothorn-internal-links counts --orderby=inbound --format=csv. -
Can I stop a suggestion from coming back?
-
Yes. Click “Dismiss” next to a suggestion in the editor panel, or “Do not suggest” in the report. The decision is stored with the post and survives index rebuilds. Dismissed pairs are listed on the report page of the target post, where “Suggest again” restores them.
-
Does it use AI or external services?
-
No. Relevance is computed on your server from your own content.
-
Does it work in my language?
-
It has been tested with English, Polish and German. Words are compared after a simple normalisation that works for most languages written with letters; languages without spaces between words are not supported yet. On multilingual sites (Polylang, WPML) links are only suggested and inserted between posts of the same language.
-
Does it see links added by other plugins?
-
It reads links in the post content. Links that other plugins add only when a page is displayed are not part of the content and are not counted.
-
Can I run it from the command line?
-
Yes, with WP-CLI:
wp indigothorn-internal-links indexbuilds the index (add--rebuildto start from scratch),wp indigothorn-internal-links orphanslists posts no other post links to andwp indigothorn-internal-links countsexports inbound and outbound link counts.wp help indigothorn-internal-linkslists all options. -
What happens to my data when I delete the plugin?
-
The index is removed unless you tick “Keep the index when the plugin is deleted”. Links you inserted stay in your posts.
