Interlink vs LinkTiller

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.

LinkTiller is a free, self-hosted WordPress plugin that finds posts and pages without incoming internal links and proposes contextual links for review. Its scan is read-only, mapping incoming links and ranking eligible source pages locally before sending a shortlist to the OpenAI-compatible endpoint and model configured by the site administrator. Suggestions show the source sentence, an exact two-to-six-word anchor already in that source, the target page, rationale, and safeguards. Scanning and requesting suggestions never edit content; every insertion requires an administrator’s explicit approval. LinkTiller verifies both pages again and refuses insertion if either changed after review. Each approved link receives a receipt, while Undo restores unchanged prior content or removes only the tagged link while preserving later edits. Requests go directly from WordPress to the chosen endpoint, which may charge separately. No usage telemetry is sent by default. A free v0.2.1 download is listed for WordPress 6.0+ and PHP 7.4+.
