The short answer: When migrating dozens or hundreds of URLs, testing each one in a browser is slow and misleads you due to local caching. Use our Bulk Redirect Checker to process up to 20 URLs simultaneously on edge workers, then export the verified status codes and landing paths directly to CSV.

Why Manual Redirect Checking Fails During Migrations

Website migrations (like moving from Magento to Shopify, or restructuring a blog) frequently involve mapping hundreds of old URLs to new counterparts. Testing them manually by pasting into browser tabs creates major issues:

  • Browser Caching: If a URL returned a 301 yesterday and you fix it today, your browser will keep loading the cached version, leading to false positives.
  • Chain Blindness: A browser only shows the final destination in the address bar. It cannot tell you if the request bounced through 4 intermediate servers along the way.
  • Human Error: Checking 100 links manually takes hours and leads to missed 404s.

Avoiding IP Rate Limits & WAF Blocks

If you run desktop crawler software (like Screaming Frog or Python scripts) from your office laptop, origin Web Application Firewalls (Cloudflare, AWS WAF) often detect the surge in traffic and temporarily blacklist your corporate IP address.

CheckURLRedirect runs bulk audits through globally distributed Cloudflare edge workers. Requests originate from thousands of dynamic edge IPs, avoiding local IP rate limits.

How to Format URL Batches for Fast Auditing

To run a bulk audit:

  1. Export your list of old URLs from your sitemap or Google Analytics.
  2. Paste up to 20 URLs into the Bulk Checker input area (one URL per line).
  3. Click Audit All URLs in Bulk.
  4. Watch the live parallel worker pool process each URL asynchronously.

What to Look for in the Exported CSV

Once the audit completes, click Export CSV Report. Filter your spreadsheet by:

  • Status Codes != 301: Flag any URLs returning 302 (temporary) or 404 (broken).
  • Hop Count > 1: Identify multi-hop redirect chains that need squashing.
  • Protocol Downgrade: Confirm no HTTPS URLs bounce through unencrypted HTTP.
