I am a new site, it has only been running for 3 months now. But for 2 of them, we have spiders on most days. I have been told it is partly due to the fact I pay for advertising on Google. Not much, about 50p (75cents) a day but this brings in between 4-5 visitors a day. But also, Google bot visits most of the time. I have also added Adsense now, this means I have at least one bot on all the time.
