Important Search Engines & Directories to Submit to:

Google's Add URL page

Yahoo!'s Free Add URL page
(Note: You need to have a registered Yahoo! account to submit here. Both AltaVista and All The Web are now fed by Yahoo!'s new engine.)

MSN's Add URL page
This is new! MSN's new search engine is still in beta mode (they built it from scratch!), and what I'm seeing so far is impressive. Usually their search engine will find you on its own, but if you're not yet listed, you can submit here.
