I don't know why but I've always viewed having a blog on professional retail sites as being tacky. At the moment my primary money site is strictly business, everything is about what I do or the products I sell. But I'm starting to warm up to the idea of incorporating a blog on my primary site. I believe that adding additional content related to my niche will make my site more relevant, expand my site's overall exposure, and keep the site a bit more dynamic for Google; which will hopefully help maintain and improve my overall rank. Before I take the plunge if I could get some feedback it would be appreciated. Should this be done? Does it matter if the articles are outside the scope of my business, but still relevant to my niche? What are some good guidelines for using a blog to improve on-page SEO, or just blogging for your business in general?
