Bot traffic

[jacal1]

How do you know how much traffic is "bot" traffic? Specifically, where am I right/wrong:

1. never devloped names that are just parked don't get bot traffic

2. previously devloped domains get bot traffic at a ratio related to previous traffic.

3. the number of previous links is the biggest factor in bot traffic

4. a site that only gets 2-5 clicks per day won't get more than 1-2 bot hits/month.

Anything else?

Thanks!!
