Automatic Internal Links for SEO vs Relinka

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.

Relinka is a WordPress plugin for mapping posts and finding internal-link issues, including broken and orphaned pages. It shows inbound and outbound link counts, a link graph, keyword clusters, and a 0–100 internal-link health score based on orphaned posts, missing outbound links, and broken links. Suggestions include a plain-English reason and use anchor text taken word-for-word from the site's content; suggestions target pages that already exist. Users approve changes before application, and each applied link has a snapshot that can be reverted with one click. The free plugin runs on the site's own server without sending content, links, or analytics to Krafts, and it requires no account or API key. Pro adds AI or semantic suggestions, bulk application, and automatic linking for new posts. Pro AI features are opt-in and use third-party services; the maker says their quality is not guaranteed. Relinka supports Gutenberg and the Classic editor and protects page-builder posts from card insertion. Requirements are WordPress 6.4 or later and PHP 8.1 or later. The free plugin is open source under GPLv2 or later; Pro costs $59 a year for one site.
