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

Automatic Plural Handling

Interlinko detects your site language (via WPML, Polylang or your WordPress settings) and applies the matching plural rules. For example:

• Add the keyword “article” and Interlinko will also find “articles”
• Add “category” and it will also find “categories”
• Works with French, English, Spanish, German, Italian and Portuguese

Nothing to configure: it is automatic.

How It Works

1. Add a keyword group with one or more keywords
2. Set the destination URL for the group
3. Configure the options: maximum links, minimum distance, and so on
4. Matching keywords become links when the content is displayed

Use Cases

• Internal linking – Link important keywords to the relevant pages on your site
• Affiliate marketing – Automatically link product names to affiliate URLs
• Glossary links – Link technical terms to their definitions
• SEO optimization – Strengthen your site’s internal link structure
