What this means in practice
Redirects preserve user access when URLs change. The strongest redirect is direct, relevant, and intentional.
Implementation path
- Map each old URL to the closest useful destination rather than a generic homepage.
- Use permanent redirects for permanent moves and update internal links so users do not repeatedly traverse redirects.
- Remove chains and loops, especially after multiple migrations.
- Keep a redirect map and test old high-value URLs after deployment.
What good looks like
A strong implementation makes the intended behavior obvious to a visitor, a crawler, and a machine reader. It has one clear purpose, uses consistent signals, and does not rely on hidden assumptions.
