• You have a page that ranks no1 for a term
• You 301 to a new url, and in time you have no1 again
• 6 months later per say you need to move that page again with another 301
What is the effect? Do 301s devalue when doing this (analogy) like a radioactive isotope? Or does Google just redirect the entire linkjuice? Does anyone know if say after 3 times a 301 won't work, for instance?
In 99% of cases after six months a page likely won't have enough decent links to an old URL to matter, since in the vast majority of cases with internal URLs the the big chunk of links are internal, which you have 100% control over.
