An instruction that sends visitors and search engines from an old [web address](https://ecosystem.samcarlton.com/domain) to a new one permanently, so old links keep working and [search rankings](https://ecosystem.samcarlton.com/search-engine-optimization) carry over.

**For example:** After a site redesign, each old page address gets a 301 redirect to its new page.
