For SEO purposes I would like to know if installation in the public-html area is better or should the installation of WP be in the root directory. I may have these confused Example when I do and FTP to my site I can either install in the (http://www) area or in the folder before this. As I have it now setup you can type "http://peterobertson.com or http://www.peterobertson.com or http://www.peterobertson.com and you still end up on my blog.
So my questions are: Which area is better for SEO purposes.
And do extraneous folders and plain html files that I use for redirects have an effect on SEO.
Thanks in advance for any help.
