Plugin Name: Broken Link Checker + Google Index Monitor

Description

Broken Link Checker + Google Index Monitor is a powerful WordPress plugin that helps webmasters and SEO professionals detect broken or problematic links—including external links—and monitor Google indexing status of all pages on your site.

This plugin is a two-in-one solution:

1. It scans your entire website for broken, redirected, or unreachable links (internal and external).
2. It checks which pages are currently indexed in Google and which are not, giving you critical insights into your site’s visibility.

✅ Key Features

• 🔗 Broken Link Detection (Internal & External)
  Scans posts, pages, and custom post types to detect broken or unreachable links—both internal and external—using intelligent HTTP response code evaluation.
• ⚠️ Redirect Tracker
  Identifies links that are being redirected (301/302), helping you spot outdated references or potential SEO issues.
• 🚫 False Positive Filtering
  Smart filtering ensures external links that are valid but flagged due to external server behavior are not falsely reported as broken.
• 📈 Google Index Checker
  Verifies if your website’s pages are currently indexed in Google using real-time Search Console API queries.
• 🔄 Combined Dashboard Panel
  View broken links and index status in one place. No more switching between plugins or services.
• 🔐 OAuth Integration with Google Search Console
  Secure integration with your Google Search Console account to monitor page indexation.

🧭 How It Works (Step by Step)

1. Activation
   After installing and activating the plugin, it automatically adds a new dashboard panel under the Tools or SEO section.
2. Site Crawl Begins
   The plugin crawls all content (pages, posts, CPTs) to identify broken or redirected links.
3. External Links Validation
   Unlike basic link checkers, it intelligently verifies external links without blocking them unnecessarily.
4. Google Indexing Scan
   Once connected to your Google account, it fetches the indexing status of all site pages directly from Google Search Console.
5. Unified Reporting Interface
   View:
   • ✅ Pages indexed in Google
   • ❌ Pages not indexed
   • ⚠️ Broken links and redirections
   • External links timing out or leading to 404s
6. Link Management Options
   From the dashboard, you can:
   • Edit or remove broken links
   • Redirect outdated URLs
   • Recheck specific pages
   • Mark false positives as safe
