PPC Spidering (Targeting)

[lamberter1]

Do PPC search engines use any spidering when you list an ad? I have noticed hits on my statcounter that are show 0 secs in duration, lots of them. Is this what is called getting "targeted?" Also, I am suspicious that this costs me clicks. Someone once told me to keep my bids at the lowest possible for the first few days for this very reason.

Thanks for any info you might have!
