Interlinq

A lightweight WordPress plugin that automatically links the first occurrence of chosen words or phrases in your site's content to a URL you specify — useful for internal linking without manually editing every post.

How it works

• You define a list of word/URL pairs from the plugin's settings screen.
• On each page load, Interlinq scans post content and excerpts (single posts, archives, home page, etc.) for the first pair whose word appears in the text.
• The first match found is wrapped in a link to its associated URL. Only one link is inserted per page load, even if multiple pairs or posts are present.
• Matching is case-insensitive and only applies to plain text already rendered by WordPress (works with both classic and block themes).

Usage

1. In the WordPress admin, go to Tools → Interlinq.
2. Add one or more word/URL pairs using the Add Pair button.
3. Click Save.
4. Visit your site — the first matching word found on a page will automatically become a link.

Notes

• Only the first occurrence of a matching word across the whole page is linked; the plugin stops after the first successful match.
• Both word and url must be set for a pair to be applied — incomplete pairs are skipped.
