I have a site that does well in Google, Yahoo and MSN. About 8-10 months ago I made a minor change to the page title, adding city and state. Yahoo and MSN reflected the change and all is well. Google has listed both titles each pointing to the same domain. Some searches show one, some the other. Since then, my
PR is up and so is my position in the search returns. Duplicate content? Sure, but Google doesn't seem to care!
