I have a local business and a website for it. I've SEO'd the crap of of it using various greyhat methods over the past year, and it now ranks on the first page for most targeted keywords. Yay. All that seems to be left now is to just keep building backlinks and/or adding content. I know google likes for websites to be active and for new content to be added constantly. But what kind of content can i add to a local business site? Not much changes on it besides some copywriting changes and maybe a price update. I have a blog on the site (http://site.com/blog/). Would it be good enough to just write interesting articles there once a week or so? Would that satisfy google's need for new content?
