Hello, We have an very large number of 301 redirects on our site and would like to find a way to remove some of them. Is there a time frame after which Google does not need a 301 any more? For example if A is 301 redirected to B, does Google know after a while not to serve A any more, and replaces any requests for A with B? How about any links that go to A? Or: Is the only option to have all links that pointed to A point to B and then the 301 can be removed after some time? Thank you for you you help!
