❓ Bulk Processing FAQ

What's the maximum number of URLs I can process?

You can process up to 1000 URLs in a single batch. For optimal performance, we recommend processing in chunks of 25-50 URLs at a time. The tool uses chunking to prevent browser crashes and maintains smooth performance even with large lists.

How does chunk processing work?

The tool processes URLs in configurable chunks (10, 25, 50, 100, or 250 URLs per batch). This prevents browser freezing and allows you to see progress in real-time. Each chunk is processed independently, and results are accumulated. You can watch the progress bar and see results as they're processed.

What file formats can I upload?

You can upload:

  • CSV: One URL per line or column
  • TXT: One URL per line
  • HTML: Extracts all URLs from the page

Maximum file size is 2MB, which typically handles 1000+ URLs comfortably.

How are duplicates handled?

When "Remove duplicates" is enabled (default), the tool will:

  • Detect duplicate URLs in your list
  • Show a warning with duplicate count
  • Remove duplicates during processing
  • Keep only the first occurrence of each URL
  • Report duplicate count in summary statistics

This ensures clean, unique canonical URLs.

Can I filter and search results?

Yes! After processing, you can:

  • Filter by status (valid/invalid/warning)
  • Search across all URLs
  • Sort by any column
  • Navigate through paginated results
  • Adjust how many results per page

This makes it easy to find and fix problematic URLs.
