Google has done many webmasterhelpvideos, some of which were published also here on State of Search. They now decided to extend these videos more into tutorials. Which simply means thy are longer and go a little bit more in depth .
In this video Matt Cutts answers a question of himself: Is there a limit to how many 301 (Permanent) redirects I can do on a site? His answer seems simple: no. But there are some ‘buts’. For example don’t 301 one page too much. Google might not follow all of them.
In the video he also mentions some other things to keep in mind:
- Avoid infinite loops.
- Browsers may also have redirect limits, and these limits can vary by browser, so multiple redirects may affect regular users in addition to Googlebot.
- Minimizing redirects can improve page speed: http://code.google.com/speed/page-speed/docs/rtt.html#AvoidRedirects
