Interlinko – Smart Internal Linking for WordPress

Key Features

• Unlimited keywords – Add as many keyword groups as you need
• Multiple keywords per link – Group multiple keywords pointing to the same URL
• Automatic plurals – Singular and plural forms are detected automatically (French, English, Spanish, German, Italian, Portuguese)
• Flexible targeting – Apply to all posts, specific categories or custom post types
• Smart links – Control the maximum number of links per post and the minimum distance between links
• Duplicate control – Choose whether the same keyword can be linked multiple times
• Link attributes – Add rel=”nofollow” and/or open links in a new tab

• Intuitive interface – Modern and easy-to-use design, even for beginners
• Safe replacement – Uses DOM parsing to avoid replacing keywords inside HTML tags, headings or existing links

Automatic Plural Handling

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

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

You don’t need to configure anything: it’s all automatic!

How It Works

1. Add keyword groups with one or more keywords
2. Specify the target URL for each group
3. Configure options such as max links, minimum distance, etc.
4. The plugin automatically converts matching keywords into links when the content is displayed

Use Cases
