Mrs Jello , PR has nothing to do with traffic..
your site has been up a while ..
I did aquicky search 3 of the main termsyou want to be found for on google.
Domains names
cheap domain names
register domain names
Domainspa does not show up even inthe first 3 pages of search
Of course you show up
#1 for "domain spa" but then asyou know..now one is searching for domain spas
I'd say you get maybe 100 uniques a day..simply because of some back links and taking into consideration you are being found for a couple of other search terms
But Hey that PR 9 sure is a turn on ! lol
