Questions about traffic...

[Ruby2Much]

I'm in the process of learning about how traffic is generated (as a performer, this was always a huge mystery). Mark and Greg are both on the phone with clients so I'm asking you XNations. What are your favourite resources on:

- pay-per-click advertising: ie: how do the brokers source and direct the traffic with such accuracy?
- search engine traffic: how does a site get listed? I understand this takes time ... why?

Any quick links you can pass my way will be very helpful.

Thanks!
