Automatic Internal Links for SEO vs LinkBoss

Automatic Internal Links for SEO is a WordPress plugin that turns eligible occurrences of stored focus keywords into links to the pages associated with those keywords. A manual SYNC records the linking rules; matching phrases become links when a page is rendered, using the focus keyword as anchor text. Users can exclude keywords, URLs, or HTML tags, adjust case sensitivity and partial matching, and add manual links. The plugin supports focus keyword fields from Yoast SEO, Rank Math, All in One SEO, and SEOPress, and works with Classic and Gutenberg editors. Its stated minimums are WordPress 5.0, PHP 7.4, and MySQL 5.6. It processes content through WordPress’s the_content filter without changing database content, but does not process Advanced Custom Fields content. Database queries are cached for a default of 14 days, and SYNC runs in batches. The free plan is free; Pro is $98.88 a year. Pro includes WooCommerce products, custom post types, continuous automatic links, background batch processing, and per-content exclusions.
