Link Whisper vs Linkagent

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.

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.
