Whether you want to test changes to your copy, HTML, CSS, javascript, or test completely different designs, phpA/B offers a way to do it. PHP-based tests run before users even begin loading your web pages. Javascript-based A/B tests cause funny twitches in your UI.

phpA/B integrates automatically into your Google Analytics, allowing deeper insight into your tests’ impact on users.  Setting up an A/B test couldn’t be easier. Almost everything is done for you. You can be running multiple tests in only a matter of minutes. Don’t let search engine robots skew your data. phpA/B automatically filters them out of your tests.
