In their own words
Automatic Internal Links for SEO
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.
Interlink
Interlink is a WordPress plugin for auditing a site's internal links, finding orphaned posts, and suggesting relevant destinations. Its audit reports total links, orphaned and under-linked posts, well-linked posts, and recommended link counts. Suggestions wait for user approval before changes; when links are added, the plugin turns existing text into links rather than writing sentences, and inserted links can be undone. Optional rules map keywords to URLs, can be restricted by shared category or tag, and can run when a post is saved. SEO tools include anchor-text diversity reporting, cornerstone-content prioritization, and an editor meta box showing links and their status. Interlink also offers CSV export, weekly scans, role controls, and settings import and export. By default, analysis runs locally against the WordPress database without external requests or tracking. If AI relevance is enabled with the user's own API key, post titles and text and candidate titles go directly to OpenAI or Google Gemini. It is free and requires WordPress 5.5 or later and PHP 7.4 or later; it is tested up to WordPress 7.1.2.
