Link Whisper vs redCacti

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.

redCacti is a web service for website health monitoring and SEO analysis. Its crawler finds broken internal and external links, orphan pages, and internal-linking gaps; it can also identify redirect chains and loops. Scheduled crawls can run daily, weekly, or monthly and follow robots.txt directives. Audits cover metadata, Open Graph and Twitter Card tags, Schema.org structured data, image alt text, and SSL certificates. For internal linking, the service suggests source and target pages, anchor text, similarity scores, impact labels, and context. Users can paste draft content for proposed link placements, but a team must review and add those links in its CMS. redCacti tracks health scores and crawl snapshots, and scheduled crawls can notify users of new issues. It says it works with any CMS, naming WordPress, Webflow, Shopify, custom stacks, and headless websites. The free plan is free for one website and up to 1,000 pages, with up to 30 results visible. Pro costs $19 a month billed monthly; Agency costs $39 a month billed monthly.
