My store uses Prestashop which has worked well for an open source shopping cart but we've always had wonky Google Analytics conversion tracking issues.<p>We need a shopping cart that allows for quick and painless A/B testing. It seems like Shopify has this feature ( http://blog.shopify.com/2010/3/22/test-test-test-more ) but I'd much prefer to host the website myself without paying a % of revenue.<p>What's the best shopping cart I can buy and host myself? Or, are the 3rd party hosted solutions vastly (or somewhat) superior?
I'd highly recommend Spree (<a href="http://spreecommerce.com/tour" rel="nofollow">http://spreecommerce.com/tour</a>). It's based around the payment processor that Shopify uses, and it supports a lot of the more advanced Google Analytics features.
This is a good quality PHP, self-hosted A/B testing system. It's free and it works well.<p><a href="http://robisit.com/8n" rel="nofollow">http://robisit.com/8n</a><p>This is a very flexible way to accomplish A/B testing and since everything is hosted on your own site, you don't need to worry about any other variables finding their way into your tests such as additional load time. It integrates seamlessly with Google Analytics and can perform true multi-variative testing.
