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!

FAQ
-
Will this slow down my site?
-
No, the plugin is optimized for performance. Keywords are processed using efficient DOM parsing when the content is displayed.
-
How do plurals work?
-
Interlinko automatically handles plurals! When you add a keyword, the plugin detects your site’s language and automatically finds both singular and plural forms. For example, if you add “product”, it will also find “products” in your content. This works for French, English, Spanish, German, Italian and Portuguese.
-
Can I exclude certain posts or pages?
-
Yes, in several ways:
- Global exclusion: In the settings, select the posts/pages to exclude completely
- Meta box: On each post’s edit page, check the “Disable Interlinko” box
- Per keyword: When creating/editing a keyword, select specific content to exclude for that keyword only
-
Does it work with page builders?
-
Yes, the plugin works with any content that goes through the WordPress
the_contentfilter. -
Can I link the same keyword to different URLs?
-
Each keyword can only point to a single URL. If you need different URLs, use different keywords.
-
Does it match partial words?
-
No, the plugin only matches whole words to avoid unwanted replacements.
-
Does it replace keywords in existing links?
-
No, the plugin safely avoids existing links, headings and other HTML elements.
-
How do I import/export my keywords?
-
Use the “Tools” tab on the Interlinko page. You can export in JSON or CSV format and import these files on another site.
