Google’s always moving and improving. I happened to try Google Voice this last week, it is pretty cool. Google did make a change to their search, this all affects SEO guys.
We saw significant increases of our SEO clients who focus on “local”. Google is working hard to figure out who local services and companies are, and they are trying to get rid of duplication or content that’s only focus is to create advertising revenue.
