I've noticed that there's usually a difference between the number of conversion reported by Google AdWords and the equivalent count in Google Analytics, despite the two accounts being fully integrated.
I've a theory to explain it as follows:
For example, it's common for the conversion count for last month to continue to increase slowly for several weeks after. This can only be because people who first clicked on an AdWords ad last month have just returned to buy.
My understanding of Google Analytics however, is that it's set to 'last source wins' as standard i.e. if a customer first visits our site via Google AdWords, but then later returns via the natural listings, Google Analytics will attribute the sale to SEO, rather than to the PPC campaigns.
This would explain why AdWords reports more conversions than Google Analytics, despite similarities in their underlying technology, but are my assumptions correct?
Can any analytics specialists please confirm that this is how the tracking of these Google products works?

I'd also be very interested to know if this is the case. Analytics definitely uses "last source wins" (and this is the number one flaw in the product IMHO) but Adwords could well be using cookies - if so, what is the duration?

AdWords cookies last 30 days apparently: http://adwords.google.com/support/bin/answer.py?hl=bs&answer=6349
Also, since writing my original post on conversion counting discrepancies, I've received confirmation theory from a Google Group admin that that is indeed how it works.

The descrepancies are even greater if you consider what happens if you advertise off-line, or do email campaigns to your customer base.

Good News:But there are great news too, and it is that now you can seeexactly what your most successful competitors' keywords are.
See the video that explains how this new PPC Spy toolworks, and get it, is 100% FREE:
A FREE Plug-In for Firefox. Simply amazing.
It allows you to browse Google and view the AdWords keywordsof ANY AdWords advertiser!
Basically, it's a small file that gets installed into yourWeb browser (i.e. Firefox).
When you do a Google search, the software automaticallyplaces a "view keywords" button below every single AdWordsadvertiser.
Click the "view keywords" button and really neat popupwindow appears that not only shows you the keywords thatany AdWords advertiser is bidding on, but it also shows youa TON of other information, like how much they're payingper click and so on.
