Automatic Internal Links for SEO

What it is

Automatic Internal Links for SEO is a WordPress plugin that turns matching focus-keyword phrases into links to associated pages. A manual SYNC records linking rules, and eligible phrases become links when content renders. The focus keyword becomes the anchor text. Users can exclude keywords, URLs, and HTML tags, adjust case sensitivity and partial matching, and add custom manual links. An activity log records rules and supports reversal. The plugin reads focus-keyword fields from Yoast SEO, Rank Math, All in One SEO, and SEOPress. It supports Classic and Gutenberg editors and requires WordPress 5.0, PHP 7.4, and MySQL 5.6. Processing uses WordPress's the_content filter rather than changing database content, and Advanced Custom Fields content is not processed. Free covers posts and pages; Pro adds WooCommerce, custom post types, continuous linking, background batches, and per-content exclusions.
