Google recently tweeted an article on this topic:
The source of the tweet is an article that’s found on WP-DD.com, titled, How to Do A/B Split Testing in WordPress Using Google Optimize.
It’s an article that gives a good overview of A/B split-testing. It talks about what A/B split-testing is, how it works, and what you need to do to run a proper split-test.
However, I do have one small issue with this article:
A (Potentially) Misleading Image
Currently, under the section titled How A/B Split Testing Works? there’s an image with the text How Split Testing Works.
(I’d put the image here, but I don’t want to risk a copyright infringement. You can simply go to the page, and scroll down to that section, and you should see the image I’m talking about.)
Anyway, in that image, there are 3 variations of a page that are tested.
3.
Not 2, as implied by the “A/B” in A/B split-testing.
To me, 3 or more versions of a web page (or variations of other elements) is multi-variate testing, and this view is shared in Conversion Fanatics’ article: A/B Split-Testing Vs. Multivariate Testing – Here’s What You Need To Know.
Anyway, that difference aside, I feel that the article mentioned above is a good place to learn how to use Google Optimize on a WordPress-based site to run A/B split-testing.
