Hmmmm.... after some more reading, I have a suspicion that it may be

> I have a website for a hotel that links out to a 3rd party booking

> a form from the hotel website linking to the booking engine and using
> pageTracker._linkByPost(this) in the onsubmit method for the form.
> When a visitor moves from the hotel site to the booking engine, you

> the site.
> However, in the GA e-commerce reports, around 70% of all transactions
> show as being referred by the hotel website, which doesn't make much
> sense.
> Here's an example of what I am seeing behind-the-scenes:
> On the main site, the following tracking code is used:
> <script type="text/javascript">
> var pageTracker = _gat._getTracker("UA-4528331-1");
> pageTracker._setDomainName("none");
> pageTracker._setAllowLinker(true);
> pageTracker._initData();
> pageTracker._trackPageview();
> </script>
> And the GA cookie for the site is something like:
> __utma 1.1629624375764636400.1224576344.1224576344.1224576344.1
> __utmb 1.1.10.1224576344
> __utmc 1
> __utmz 1.1224576344.1.1.utmcsr=google|utmccn=(organic)|utmcmd=organic|
> utmctr=cityinn%20london
> When you go through to the booking engine it contains the same GA
> code:
> <script type="text/javascript">
> var pageTracker = _gat._getTracker("UA-4528331-1");
> pageTracker._setDomainName("none");
> pageTracker._setAllowLinker(true);
> pageTracker._initData();
> pageTracker._trackPageview();

> utmccn=(organic)|utmcmd=organic|utmctr=cityinn+london&__utmx=-
