Want to start a split-test right away? Choose a unique test id, provide a piece of code for the first group and a piece of code for the second, and define an id to indicate a conversion.
For example, let’s define a split test called clothes. In the first group, we’ll say “Your clothes are red.” In the second group, we’ll say “Your clothes are black.” When we convert, we’ll use the id clothes_complete.
Then, we’ll do this on our test page:
<a href=”convert.php”>[ab-see id=clothes]</a>
And on the page we want to get to:
[ab-convert id=clothes_complete]
That’s it!
Inspired by the practice of copying the smartest people you know, AB-See is based on Patrick McKenzie’s A/Bingo (http://www.bingocardcreator.com/abingo) and Ben Kamens’ GAE/Bingo (http://bjk5.com/post/10171483254/a-bingo-split-testing-now-on-app-engine-built-for).

Easiest way to create split tests on your WordPress sites, right from the content editor!
Improve your website and start measuring your audience now.
Create A/B tests right in the content editor. Test which button colour works best, what content drives people to engage, anything you can imagine!
<h4>Add A/B Tests from Anywhere in the Content Editor</h4>
A/B Testing for WordPress allows you to create split tests right from the visual content editor. Measures the results of your tests and shows you which variant is the most popular choice.
You add a block to your content which you can fill with anything you want to, and switch between variants instantaneously to preview what visitors will see. Define distribution weight, pick the goal of the test, and off you go!
Place tests inside posts, pages, custom post-types, or any part of your template using shortcodes.
<h4>Safe for SEO</h4>
Everything has been implemented with SEO in the back of the mind, which means the plugin will do nothing to affect your SEO. It works just like most A/B testing tools out there, but natively from your own WordPress site without the use of 3th-party services.
<h4>Measure Results</h4>
A/B Testing for WordPress provides an overview of running tests and the measured results. It also shows the statistical significance of the test results so you can be confident a test is successful or not.
When you are done running your tests and can come to a conclusion you can break the winning variant out of the test and remove the test from the content with just one click.
<h4>Integrates with Other Plugins</h4>
A/B Testing for WordPress integrates with other WordPress plugins. This provides a streamlined experience to test variations of what the integrated plugin has to offer. Think form submissions, sign ups, product sales.

A/B Testing for WordPress

I've had the idea for an A/B testing plugin for WordPress for years and shared it with Gaya a few weeks ago. Not saying he got the idea from me, he may have already been thinking along the same lines. Given his experience with A/B testing tools in other website builders, he had a first prototype ready just a few days later. 

And it's good! This is already a great tool to test variations of your content to see what drives the result you're looking for. And it's been improving steadily over the last few weeks.

Knowing Gaya and his iterative approach to building great and usable software (e.g. Thyme), I can't see how this will not be a success.
