One redirect per line: the old address, then the new one. You get server rules ready to paste, plus warnings for duplicates, loops and chains.
Separate them with a space, tab, comma or ->. Full URLs and paths both work; lines starting with # are skipped.
Good to know
- The Apache rules use
RedirectMatchwith exact matches. PlainRedirectalso catches everything that starts with the old path, which surprises people. - Use 301 for moves that are permanent (search engines pass the old page's ranking on), 302 for temporary ones.
- Try the rules on a staging copy first, and point every old address straight at its final destination - chains slow visitors down and waste crawl budget.
