Core+ Links vs Linkagent

Core+ Links is a self-hosted WordPress plugin that finds and manages internal links using a local index of site content. In the Gutenberg block editor, its sidebar ranks possible destinations with eight weighted signals and shows match strength. You can revise anchor text, insert a suggestion in one click, or dismiss it. Keyword rules scan pages for matches that you review before applying. A change history can undo one edit, a complete run, or links created by a keyword rule. Reports identify orphan pages without inbound links and underlinked pages with fewer links than their importance calls for. Link Health flags links to unpublished, trashed, or missing pages, but does not inspect external URLs over HTTP. Indexing, ranking, auto-linking, and Link Health run on your server and database. The free plan is permanent and includes background indexing and scheduled reindexing. Requirements are WordPress 6.6+, PHP 7.4+, and Gutenberg. Upcoming Pro plans have no listed prices.

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.
