About the 301 Redirect Generator

Site migrations live or die on the redirect map. This tool takes a two-column list of old and new URLs and writes the rules in the syntax your server actually wants: Apache rewrite or redirect directives, nginx location or map blocks, Netlify _redirects, Vercel JSON, or Cloudflare bulk redirect format.

Before generating, it checks the map for the problems that cause outages. A redirect loop, where A points to B and B points back to A, makes a page unreachable. A chain, where A goes to B and B goes to C, works but loses a little signal and adds a round trip, so the tool offers to flatten chains so every old URL points straight at its final destination. Duplicate sources, where the same old URL appears twice with different targets, are ambiguous and get flagged.

You can choose between a 301 permanent redirect and a 302 temporary one. For a migration you almost always want 301, because it tells search engines the move is permanent and passes the ranking signal to the new address.

Frequently asked questions

When should I use 301 rather than 302?

Use 301 when the move is permanent, which is nearly always the case in a migration. It tells search engines to transfer the old address's signals to the new one. Use 302 only when the original will genuinely return, such as during a short campaign.

What is a redirect chain and why avoid it?

A chain is A pointing to B pointing to C. It works, but each hop adds latency and browsers give up after several. Flattening the map so every old URL points straight at its final destination is faster and more reliable.

What happens with a redirect loop?

The page becomes unreachable and the browser shows an error after a few hops. The tool detects loops in your map before you deploy them, which is considerably better than finding out in production.

Do redirects pass full ranking value?

A permanent redirect to a closely related page passes essentially all of it. Redirecting everything to the home page does not, because the destination has little to do with the original and search engines often treat such redirects as soft 404s.

How long should redirects stay in place?

At least a year, and longer if the old URLs still receive traffic or links. Removing them too early breaks every existing link to the old address.

Does this tool test the redirects?

No. It writes the rules. Test them on a staging environment before deploying, because a mistake in a rewrite rule can take a site offline.
