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.
Linkagent
Linkagent crawls websites to identify missing internal links and add links after users approve them. Links can be delivered through a script, WordPress plugin, or JSON API. Its analysis reads a sitemap and maps topics, clusters, orphan pages, click depth, and the in-text link graph. Suggested anchor phrases come from existing page copy, and optional AI review checks them against their original sentence. Crawling, clustering, scoring, and anchor selection work without an AI key; a Claude API key enables additional review. Users approve or reject suggestions, and those decisions persist across re-crawls. Suggestions are balanced at roughly one new link per 250 words, with limits on new inbound links and repeated anchor use. The asynchronous embed script is about 2 KB and wraps existing text without adding or moving page content. Linkagent supports WordPress, Next.js, Shopify, Webflow, and other CMSs. Self-hosting keeps content, link graphs, and review decisions in the user's own Postgres database. Self-hosting costs nothing and requires your infrastructure; hosted plans start at $29 a month.
