Interlinko – Smart Internal Linking for WordPress

Interlinko is a WordPress plugin that automatically converts the keywords you choose into links. It is built for internal linking: pick a keyword, pick a destination, and every matching post links to it from then on.

Key Features

• Unlimited keywords – Add as many keyword groups as you need
• Multiple keywords per link – Group several keywords pointing to the same URL
• Automatic plurals – Singular and plural forms are matched automatically (French, English, Spanish, German, Italian, Portuguese)
• Never links a page to itself – Self-referencing links are skipped, so your internal link graph stays clean
• Flexible targeting – Apply to all content, to specific categories, or to selected post types
• Smart links – Control the maximum number of links per post and the minimum distance between them
• Duplicate control – Decide whether the same keyword can be linked more than once
• Link attributes – Add rel=”nofollow”, open in a new tab, and set your own CSS class
• Statistics – Track how many links each keyword produces, counted in the background
• Import/Export – Save and restore your keywords in JSON or CSV
• Global exclusion – Select posts and pages to exclude entirely
• Per-keyword exclusion – Exclude specific content for an individual keyword
• Preview – See exactly which links would be added before you commit
• Whole words only – Keywords never match inside a longer word
• Safe replacement – DOM parsing keeps keywords out of HTML tags, headings and existing links
