This is really useful tool because bloggers often need this function, specially when they want to redirect an old web page to a new web page. Here is how you can redirect a URL to another URL using blogger's official tool.
- You need 2 web page addresses for that. The first URL is the address which should be redirected to new URL.
- Once you have obtained both URLs, go to; Settings > Search Preferences > Errors & Redirects > Custom Redirects
- Add the proper webpage addresses in both of the fields and click on SAVE link. You can even select PERMANENT which means the old web page has permanently moved to new one.

You can redirect as many URLs as you want because blogger has not imposed any limit so far. You should also use customized 404 error page feature of blogger.
