Do you rely on search engines for traffic?

[cpvr]

This brings up a nice little discussion, because I've seen many websites come and go throughout my webmaster career, and I've seen some websites die because of their rankings going down and such.

So, I'd love to ask all those webmasters out there if they rely on search engines for traffic or not.

As we all know, getting ranked, and ranked well on search engines can help or break a site, so I'm one to say that some of my partners' websites rely soley on search engines and word of mouth, while my sites rely on word of mouth.

How about you?
