I'm working on a very large (over 2500 pages), very old website (with pages created in the late 90s). The structure of the site is a mess (it still shows subtle sings of Frontpage!). We are trying to move to a more uniform, dynamic solution.
My question is: what sort of implication will there be on search rankings if we implement 301 redirects from the very old pages (that are poorly named) to new pages which follow a uniform pattern.
Some of these pages have external links pointing to them and others (most) just have internal links pointing to them which will be adjusted to the new urls.
Does the age of the page have a significant implication on rankings? Is there a better way to this than 301 redirects?
Thanks for the help
