Automate WordPress Internal Linking for SEO — Free API for Developers

Internal linking is one of the most underrated SEO tactics. Every SEO audit tool tells you "add more internal links," but none of them tell you which links to add or where . I built a free API that analyzes your WordPress content and returns specific internal link suggestions — exact anchor text, source URL, target URL, and relevance score. The Problem You have 50+ blog posts. Each new article should link to 3-5 existing posts. Manually reading through your entire archive to find relevant links? That doesn't scale. Plugins like Link Whisper ($77/year) solve this, but what if you want: Programmatic control — integrate with your CI/CD or content pipeline Bulk analysis — analyze hundreds of posts via script Custom logic — filter by category, minimum relevance score, etc. How It Works Send your article content + a list of existing posts. The API returns ranked link suggestions. Python — Analyze a New Post import requests url = " https://wp-internal-link-api.p.rapidapi.com/analyze " headers
