I doubt freewebs is going anywhere, they are a very solid host.
I can't speak for anyone else's server space, But I have a reseller account
My users have full control via CPanel
With the following features:
Disk space 100 MB
Bandwidth 1 GB
Php, cgi, perl, front page
FTP access
Fantastico with over 40 Pre-Installed Scripts
3 MySql Databases
5 Email Accounts
5 Sub Domains
Plus, I have the ability to adjust any of the above to meet a users individual needs.
SEO is great to do....And yes I mod all my sites to please the bots......But, first you need a site, then content is king.
