Readme github.com/ikoanti/wp-internal-link-automator ↗

A lightweight WordPress plugin that automates internal linking structure to improve SEO authority flow (PageRank) without over-optimizing.

🎯 The SEO Problem

Internal linking is critical for distributing link equity and helping Google crawl a site. However, manual linking is slow, and inconsistent. Over-linking (linking the same keyword 10 times in one post) can be seen as "keyword stuffing" by search engines.

💡 The Solution

This plugin parses post content and automatically links targeted keywords to specific destination URLs.

Key SEO Features:

  • Frequency Capping: Uses a limit=1 regex logic to only link the first occurrence of a keyword per post. This ensures natural-looking density.
  • Word Boundaries: Uses Regex \b boundaries to ensure "Cat" doesn't trigger a link inside "Catastrophe".
  • Performance: Hooks into the_content only on singular views to minimize database impact.

🛠 Installation & Usage

  1. Download the repo as a ZIP.
  2. Upload to WordPress via Plugins > Add New.
  3. Left Menu Locate: SEO Linker.
  4. Add your keywords in the format: Keyword|URL
