Somebody help me with this dilemma. Does the search engines treat http://www.domain.com and http://domain.com any differently? What bout changing the blog url in wordpress admin page>settings>general. What effect does it have if you change the url to include www Please help
it doesn't matter which one you go with. Just remember that www. or no www. you have to be consistent. it's two different URLs being served, so just stick with one. Personally I'd go with the www., but site's like twitter.com don't. It's your call, just be consistent.
