Hello -- My website is currently under development and I would like to have a great, easy to use blog. I am not tech-savvy so I want to use a WordPress site for the blog. From what I know about SEO, the blog needs to live under my top-level domain in a sub-directory for full SEO benefits. If my website is goliathvs.com, I should have the blog at goliathvs.com/blog or blog.goliathvs.com and not have the blog at goliathvs .us. This seems obvious. However, my developer says that adding a WordPress site to my top-level domain will present major security vulnerabilities and add too much stress on our server. My question is, how necessary is it for the blog to live under my top-level domain for SEO? Is it pointless to use resources on a blog at goliathvs.us if my actual business is housed at goliathvs .com? Also, is a .us domain a bad idea in general? I am in college grinding away, trying to start an online business (not actually goliathvs.com) and don't have the money to hire a SEO consultant. So any help is much, much, much appreciated! Thanks
