I have a few pages to A/B test, and I am looking for the best tools to use for this? Is there a "standard" or favorite industry tool?

  • If this question is about "Best" A/B tools, then I'd like to see motivation from answerers on why their tool is the best. Right now it's just a list of A/B tools which you could get by Googling. What can we do to improve the quality of answers here to make this a unique resource so people don't have to Google?

Google offers a free AB tester callled Website Optimizer


I would advise you to try this new tool: http://visualwebsiteoptimizer.com/

I think this should be the future of A/B testing! You can use it without any html/css knowledge. It is for business users, who know marketing and not programming.

And it is reasonably priced!


I'm a big fan of Optimizely.

Visual editing. Easy goal setting. Real-time reporting. Retroactive goal data. Simple to use interface.


I've used Vertster and found it to be a worthy (though not free) tool for A/B and multivariate testing.


Omniture (now Adobe's) Test and Target
