A/B testing (sometimes called split testing) is comparing two versions of a web page to see which one performs better - sells more products or signs up more users or whatever other goal you are optimizing for.
You compare two versions of your page (let's call them A and B) by showing version A to some visitors and version B to other visitors. Both pages usually run in parallel (at the same time). Those visitors who see version A should never see version B, and vice versa.
You run the test to collect enough data and then select the winning page - i.e. the one that gives a better conversion rate.
There are many paid products that allow webmasters to run A/B testing. For example, VWO.com will cost you $60/month or more, b/c like most of these tools they demand higher fees if your site has more traffic/visitors.
However, it should not be difficult for .NET programmer to integrate A/B testing methodology with Google Analytics reporting tools and have a free A/B testing tool with unlimited test traffic / iterations
How can we setup A/B testing using ASP.NET MVC backend and Google Analytics Reporting tools? Are there any Open Source libraries that facilitate A/B testing with ASP.NET MVC and Google Analytics?
Obviously, the first place to take a look at is here:
Google Analytics Content Experiments
This is GA's variation of A/B testing
