I have a used car dealership that I'm trying to rank. I have created quite a bit of content on it but have quite a bit of car information in my head (been in the business for 15 years). I'm reading how much google loves blogs and the fact that its an effective way to get your backlinks and keep it fresh I'm sold. My question is this. Is it a good/bad idea to have a blog on my brick and mortar website or is it smarter to create a blog from completely scratch and just backlink to my web page?
