I'm building a site around the first really promising keyword niche I've found since learning exactly what that means (ie high search volume, mediocre competition), and I really want to get everything right. It's going to be a large static content site, and I've read in the forums a few times that attaching a blog to such a site can really help you in the SERPs for various reasons. My question is this. What is the most effective place to put the blog? Would it be blog.sitename.com or sitename.com/blog? Do the links I build to the subdomain count towards the overall backlink count of the parent domain? I feel like blog.sitename.com is more professional, but I want to make sure I optimize my SEO efforts. Thanks for any help.
