Description
Aliamin Auto Internal Linker reads your published post titles, builds a keyword index, and inserts contextual internal links into post content at render time.
The free version includes Smart Mode, which extracts phrases from post titles using title structure and configurable rules. The original post content in the database is not changed.
Key features
- Builds a keyword index from published posts
- Inserts links through the
the_contentfilter - Does not rewrite or overwrite stored post content
- Lets you control maximum links per post and per keyword
- Supports minimum word spacing between inserted links
- Lets you skip the first paragraphs of a post
- Supports a configurable keyword blacklist
- Can skip headings when inserting links
- Includes a manual index rebuild tool in Settings
How it works
- The plugin scans published posts and extracts keyword phrases from titles.
- It stores the generated keyword index in WordPress options.
- When a single post is viewed, the plugin checks the rendered content and inserts matching internal links.
- If the plugin is deactivated, the inserted links disappear because the stored post content was never modified.
Free and Pro
The free version includes Smart Mode.
The Pro version available on the plugin website adds optional AI-assisted extraction and multi-site licensing.
External services
The free version works without any external service.
The Pro version described in the settings screen can connect to the Anthropic API for optional AI-assisted keyword extraction during index rebuilds.
If that optional Pro feature is used, the plugin sends post titles and the related internal post IDs needed to match the generated keyword phrases back to the correct posts.
