backdraft, we also see spurts of conversions (much like the Zombies but useful!). We don't have Adwords so it's not that. Take a look at Adfree stats, you get to see the referer string (unless SSL blocked bt Google, why would they do that I wonder?!) & IP address which you can then do some really useful digging on. I ues it in conjunction with GA, real time IIRC is also available on a service called getclicky.
RE:spurts, a few sales in the AM then dead, then sales @ 16:12, 16:17, 16:21 & 16:37 the dead again.
