I believe this has been asked before, but I am hoping someone can answer it again. I do a blog for an ecommerce site and it was suggested that maybe we should move it to its own domain like we were originally going to do. It is now currently on oursite.com/blog. It seemed to do well at first, but over time it seems like Google hasn't been as kind to it.
Maybe ignoring that this is an already an existing blog, is it better from an SEO standpoint to have your blog on your site or its own?
