I've got two questions before I do this (one shouldn't be in this forum...but i put it here because the other is my main question) The first one is my site is a PR 5 at the moment, with about 15000 pages in google...and most of those of course are site/forum.php?blahblah now if i change to forum.site.com/index.php?blahblah....how do I permanently redirect all the old forum.php to forum.site.com so i don't get hit with duplicate content?...or since there won't be anything at forum.php anymore...will i not get duplicate anyway? second question...would this hurt my page ranking to switch and then google will have to totally reindex me?...if it will be bad that way then i might just leave it... the reason i want to do this is i want to make it consistent...forum.site, blog.site, directory.site, etc...
I'm under the impression that using the name in the x.php may be better or at least an alternate idea too. www.domain.com/blog.php, www.domain.com/directory.php etc -Raymond
Hmm...i suppose I could do it like that...i just happen to like the subdomain look better I'll see what the general consensus is from others before I make up my mind
You should use 301 redirect to redirect any request for forum.php to corresponding page of forum.site.com. If you do that google will automatically update its index to change any reference to forum.php to forum.site.com. Using 301 redirect is important or else you will loose all the back links you have recieved to the moved pages.
i'm probably just going to keep it the same and change the subdomains to /directory... it'll be easier to maintain i think thanks for all the info guys
