Julia,
Blue Voda's KeyWordDigger is an awesome tool. I support it 100% Though I did want to set out these key word links. One is for Google, the other for Yahoo/O*****re. They may help, may not. I hope they do though. :o)

Also here is a list of search directories to help you get your site out there, some of these are free some arent.
