Interlink vs Link Whisper

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.

Link Whisper is a WordPress plugin and Shopify app for managing internal links. It suggests links for posts, which users can review before adding, and can draw on Google Search Console data and keywords from Yoast SEO, Rank Math, All In One SEO, and SEOPress. It supports editors and builders including Classic Editor, Gutenberg, Beaver Builder, Cornerstone, Elementor, and Divi. The plugin can process Advanced Custom Fields content and configured custom metafield-based content. Premium includes reports on link statistics, domain linking, clicks, and broken links. Licensed sites can suggest outbound links to one another, but inbound cross-site suggestions are not supported. Free access includes manual insertion of outbound suggestions; a limited-time Premium trial is available, and paid plans start at $97/yr. The maker says Premium does not send site content or personally identifiable information to its servers, though license checks transmit the license key, site URL, and subscription level. AI processing sends only selected post content to OpenAI; click tracking may store visitor IP addresses and site IDs on the customer's site.
