For some strange reason Google is refusing to let some home pages rank well for the exact match domain. I have been working with a site for several months where no pages showed up in the top 500 for the exact match domain search. It was a one page site when I picked it up, but now has a dozen or more good quality, completely original articles. Over the past few weeks about 5 of the article pages started showing up in the top 200 for the exact match domain search, but the home page is nowhere to be found in search results--for any search phrases. This is the first time I have seen that happen with a .net EMD.
Google is as Google does.
