Question: What is the purpose of a URL mapping file?
- To create a map for Google to follow the redirect path
- To map out how many 301 vs. 302 redirects you need
- To map the old site URL to the new site URL
- To avoid pages being interpreted as soft 404's
Explanation
A URL mapping file links every old URL to its corresponding new URL, ensuring proper 301 redirects are implemented during a site migration. This preserves SEO equity, prevents 404 errors, and maintains search rankings. It provides a clear reference for developers and SEO teams to manage page-level redirects systematically. Proper mapping supports a smooth migration and protects organic traffic.
Why the other options are incorrect
A) The file itself does not create a map for Google; it guides redirect implementation.
B) While it may inform redirect type, its primary purpose is mapping URLs, not tallying 301 vs. 302.
D) Avoiding soft 404s is a result of correct redirects, not the direct purpose of the file.
