I'm in a tough situation here - I've just converted an 8 year old site that has tens of thousands of links indexed in Google and Yahoo as http://www.domain.com/subdirectories/ formats. I'm told that http://domain.com and http://www.domain.com and http://subdomain.domain.com are seen by Google and other search engines as three different sites. If you've got a forum at http://www.domain.com/forums and a blog that may have a lot of posts to import at domain.com/blogs, technically I'm told that search engines will see these as two separate sites and you will not obtain the benefit of a large amount of combined content. Regardless of what a couple of brilliant scholars hoping to save the world from typing three characters may think, my understanding is that it's a very bad idea to change all my links on my site to remove the "www" - even with a 301 redirect. And who knows what other config files are set to go to "www" which will be forever require redirection. Anyways, you get the idea.
1) Why isn't there an option that clearly allows you to use or not use the "www" during install? This forced requirement seems almost contrary to the open in "open source."
2) How can I get these blogs to use the www? I've looked at various posts and it's difficult to say what works exactly without tinkering and potentially screwing up the site. I would think it a good idea to sticky an official instruction for this.
3) Is there anyone that can say with assurance that moving an entire site from the www to a non-www approach won't result in lost links in search engines and other locations? When I mean assurance, I mean a statement of fact, not a probability. If there is a probability that things might not go well then not having a "WWW" option seems like a rather poor decision. Willing to hear your thoughts on this one.
Thank you for all comments
PS - here's another funny item I just noticed. All the instances of adding a "www" in these Wordpress forums results in an automatic hyperlink. But if you DON'T type in the www in front, then the URL will just appear as text. Check it out. http://www.domain.com versus domain.com. Another reason why leaving out the "www" makes no sense at all, regardless of carpal tunnel issues.
