Split testing works. Use it well, and you will improve your conversion rates, and, thus, your profits. And, if you are advertising, or have significant product costs, raising your conversion rate just a little can raise your profits a lot. But there are many different kinds of split testing software out there.

Split testing works. Use it well, and you will improve your conversion rates, and, thus, your profits. And, if you are advertising, or have significant product costs, raising your conversion rate just a little can raise your profits a lot. But there are many different kinds of split testing software out there.
Let me give you an overview, so you can understand the choices you have before you. I’ll walk you through the main distinctions that rule the field.
The first main division is between simple split testing (single variable) and multivariate testing.
Simple split testing is easy. You’re just "trying stuff" one thing at a time. You want to try a different headline? Split test it. When that test finishes, you want to "try" something else? Split test that. You can test one alternative version or many. As long as it’s a single element of your page you’re testing, that’s simple split testing. All you need is a tool that rotates the different versions of the headline (or whatever) on your page, and keeps track of which one produces the most sales.
Google offers a single variable split testing tool, but you have to have an Adwords account to use it.
With multivariate testing, you can test many factors at the same time on your page. So, instead of just testing your headline, you can test your headline, your offer, the P.S. statement, and your lead image all at the same time. And with multivariate testing, if it’s set up right, you can use the same amount of traffic testing many variables that you would use to test a single variable.
So there’s the main distinction between single variable testing and multivariate testing. But once you get into the realm of multivariate testing the options seem to multiply again. One difference among multivariate tools is between tools that are hosted on someone else’s server, and ones that you install on the same server as your webpages. Hosted solutions can be slower, and more expensive, but you don’t have to install any software.
The Split Test Accelerator is a good choice if you want to install the software on your server. Kaizentrack is another optoin. If you want a hosted solution, you can look at Sitespect and Vertster.
Another 3-way distinction among multivariate split testing tools is between Taguchi-based systems, Full factorial systems, and Random independent rotation of factors. With a Taguchi system, you run traffic to only a small, carefully-selected subset of the possible combinations of your factor levels. This allows you to cycle through every combination every 12, 18, or 36 pages, whichever the case may be for the test design you’re using. This allows you to find the best combination very quickly. Some care does have to be taken to avoid interaction effects among the factors. Taguchi-based tools include the Split Test Accelerator and Vertster.
If you want to get around interaction effects you can with a full factorial tool. It will take more traffic to avoid the interactions -- a lot more -- but with a FFT, like Google’s Website Optimizer, you can just see how every combination plays out, and live with the interactions.
The Random independent rotators are a third option. These treat factors independently. So you can just plug in a new factor with as many options as you want at any time, and ignore the fact that other factors are being tested at the same time. This is the most flexible form of testing, but it is also plagued with the most interaction effects.
Now that’s just the overview. There are many other features to compare and questions to ask. Does a tester allow you to exclude bots and spiders? Does it allow real time access to data? What kind of reports does it show? What kind of information does it track for each visitor, and is the visitor-level data available for viewing. Etc.
