🔗 External Link Finder Tool – Identify Outbound Links with Precision

External Link Finder is a web-based utility designed to scan multiple websites simultaneously and extract all outbound (external) links found within their HTML content. Built for performance and clarity, this tool helps SEO professionals, webmasters, digital marketers, and security analysts easily audit external linking patterns across up to 200 websites at once.

🔍 Key Features

✅ Bulk URL Analysis

Paste up to 200 URLs, and our tool will asynchronously process each website using advanced cURL multi-handling, allowing for efficient and parallel requests.

🔗 External Link Extraction

Each webpage is scanned for all <a> elements. The tool then identifies and lists external domains that differ from the source domain and are not on a predefined blacklist (e.g., internal or commonly ignored domains).

💡 Smart Blacklisting

Links pointing to internal domains or blacklisted ones are ignored, giving you a clean and concise list of only relevant outbound references.

⚡ High Performance

  • Utilizes parallel cURL requests for faster batch processing.
  • Optimized DOM parsing with DOMDocument and XPath for quick and accurate link extraction.
  • Employs output buffering, memory cleanup, and timeouts to maintain stability under load.

🧠 Caching (Optional)

Built-in caching allows previously processed URLs to be reused (configurable), reducing server load on repeated queries.

🖥️ User Interface Highlights

  • TailwindCSS-powered modern, clean UI.
  • progress bar, with percentage updates.
  • per-URL processing status: Pending, Processing, Completed, or Error.
  • Displays:
    • Source URL
    • External domain extracted
  • Timing breakdown:
    • Average time per URL
    • Total processing time

📋 Exporting

Results can be copied to clipboard in a tab-separated format for easy use in spreadsheets or further processing.

🔐 Privacy & Safety

  • Uses noindex, nofollow meta tags to prevent indexing.
  • No data is permanently stored unless optional caching is enabled.
  • All HTML parsing and link extraction happen server-side, protecting client inputs.

🛠️ Technical Stack

  • PHP with cURL, DOMDocument, and simple_html_dom.php for HTML parsing.
  • JavaScript/jQuery for AJAX-based real-time interaction.
  • TailwindCSS for responsive and styled frontend components.

💼 Use Cases

  • SEO Audits: Quickly identify which domains a group of sites is linking to.
  • Affiliate Check: Verify if any outbound traffic is being directed to affiliate networks.
  • Security Review: Audit unexpected third-party links for potential phishing or malicious redirects.
  • Content Validation: Ensure links go to reputable sources.

🚀 How to Use

  1. Paste up to 200 URLs into the text area.
  2. Click “Start Processing”.
  3. Watch the progress bar as each URL is processed.
  4. Review or copy the results once completed.

📦 Optional Enhancements

  • Add more domains to the blacklist via the blacklist.php file.
  • Adjust concurrency or timeout settings in the backend to fit your server resources.
  • Enable or disable caching behavior depending on your workflow.
