Quickstart.

Two sitemaps in, one CSV out. From zero to a clean redirect file in about five minutes.

Before you start

You need a URL list for the old site (the one with rankings) and a URL list, sitemap, or live URL for the new site. Sitemaps are the cleanest source.

Five-step flow

  1. Create a project. A project is a folder. Name it after the migration (e.g. Q4 migrations) or the client.
  2. Create a map. A map is one source domain to one target domain. Click + New map from inside a project.
  3. Add sources. Side-by-side: old site on the left, new on the right. Pick a source type per side: sitemap URL, sitemap file, GSC export, plain text, or live crawl.
  4. Run match. Three passes (exact, fuzzy, wildcard) score every old URL against the new index. Live progress shows in the ring.
  5. Review and export. The super-table groups rows by confidence band. Accept, manually override, or mark unmatched. Export as Apache, IIS, Nginx, or plain CSV.

Tips

  • Wildcard collapse turns hundreds of URLs into one regex line. Verify children before exporting.
  • Anything below 0.75 confidence surfaces for review by default. Bands carry recommended actions, not just scores.
  • Export from the /review page: pick CSV, .htaccess, nginx, or JSON.
