what should I use to find duplicate URLs from filters and parameters

To find duplicate URLs caused by filters and URL parameters, use a URL normalization + deduplication approach.

Best tools / methods

• Screaming Frog SEO Spider
  • Crawl the site and export URLs.
  • Use filters to spot parameterized URLs and near-duplicates.
  • Good for medium-sized sites.
• Sitebulb
  • Great for finding duplicate pages, parameter issues, and crawl patterns.
• Google Search Console
  • Check Pages and URL parameters issues indirectly through indexed URLs and duplicates.
• Log file analysis
  • Useful if you want to see which parameter URLs are actually being crawled.
• Custom script / spreadsheet
  • Export URLs and normalize them by removing tracking parameters and sorting/removing query strings.

What to look for

• URLs with different parameters but same content, like:
  • /category?sort=price
  • /category?sort=new
  • /category?page=2
  • /category?filter=red

How to identify duplicates

1. Crawl all URLs
2. Normalize URLs
   • Remove tracking parameters like utm_*, gclid, fbclid
   • Decide which parameters matter and which don’t
3. Group by canonical path
   • Compare pages with the same main path and similar titles/content
4. Check canonicals
   • Make sure duplicates point to the preferred version
5. Review indexing
   • Use GSC to see what Google chose as canonical

Quick recommendation

If you want a practical SEO workflow, start with: Screaming Frog + a spreadsheet/pivot table + Google Search Console
