If you need technical details on third party cookies and other interesting (cross-domain stuff) here is a presentation that I referred to: http://www.slideshare.net/SlexAxton/breaking-the-cross-domain-barrier http://www.slideshare.net/SlexAxton/breaking-the-cross-domai... Essentially, you load a different domain in IFRAME which sets the cookie. IE requires you to set a P3P header for it to work properly. And Safari required the visitor to have visited the website before. To get across this, you first load a different domain in IFRAME and then have form submit to that domain (with target being IFRAME). (IE7 opens a new window in this case since it doesn't recognize target attribute). Crazy cross-browser issues. I wish there were a simpler way of doing cross-domain tracking.

Are you saying this was how things were done before? Or this is how things are done now? P.S. Also, does your software's MVT optimize itself like genetify - http://www.shoemoney.com/2010/03/03/split-testing-with-a-genetic-algorithm/ http://www.shoemoney.com/2010/03/03/split-testing-with-a-gen...

  This is a new feature that we have released today! I'm excited about this because it solves pain-point of a lot of our users. No, VWO doesn't dynamically optimize because statistics become s really complicated once you try to model such optimization. As far as I know Genetify (or any other tool out there) doesn't have a statistically valid method of optimizing the test (while it is running). The math required to do such optimization while maintaining statistical validity is beyond me, at the moment. (Though I am actively researching on this front. Any pointers/links will be appreciated)

    So no more iframing etc? Genetify is open source - http://wiki.github.com/gregdingle/genetify/ http://wiki.github.com/gregdingle/genetify/ - you can have your programmer go through it for the algorithm. That'd be a good starting point. Statistically valid optimization would be a HUGE plus. Enough for me to pay for VWO instead of using genetify.

      Genetify doesn't have a statistically valid algorithm so no point looking at its source. Moreover, there are some basic optimization features already built into VWO: http://visualwebsiteoptimizer.com/split-testing-blog/why-ab-testing-is-truly-risk-free-even-when-every-lost-sale-matters/ http://visualwebsiteoptimizer.com/split-testing-blog/why-ab-... Third party cookies (via IFRAME) is a choice, it isn't enabled by default for all tests.

        Ahh I see. Cool.
