I've followed this Panda debate from the start and after a year and a half or so, I'm pretty confused about what the current thinking si about splitting a site up.
I haven't done that, but I might do so soon.
Here's the deal.
The existing site has several parts that could easily be separate sites in their own right. Traffic to most has been pounded into the ground by that angry little Panda, but I'm not sure which part of the site is the real problem.
And I'm about to change hosting so I figure this is the time to make the changes if I'm going to.
I'm wondering if subdomains are the best way to split the site up.
Or would new domains be better?
If new domains, would it be better to use the .net/.org/.info/.etc version of the existing example.com. This would be easy, I already own these names.
Or, would it be better to start over with the split off sections with new unrelated domain names?
I assume that if subdomains or the various .tld versions of example.com are used, interlinking at some level would be ok, but what level?
If the split off sections move to separate unrelated domain names, how risky would interlinking the old example.com to the new domains be?
I'm not worried about getting links to these new domains, the split off sections of the existing site are such that I'm pretty confident I can ask for and get link modifications from enough of the sites that now link to the old site.
Is it advisable to (301) redirect affected urls from the old site to the appropriate new site? This might help the search engines find the moved content faster, but I could live without that if it makes a big difference.
