CRO A/B TestingĮach individual page has multiple variations: a control, and at least one variant Both tests are important steps in improving online performance but target very different metrics. In summary, there are several key differences between CRO and SEO A/B testing. With Google as the determiner of how these pages will rank, duplicated content (which Google is against) is not encouraged.ĬRO A/B testing, on the other hand, requires two versions of the same page to be live at the same time so data can be collected and compared. In SEO split testing, there is only one version of each page at any time. Data is collected from how users interact with the version of the page they are assigned to and compared. Thus, it is the users themselves that are split into controls and variants. In CRO A/B testing, two versions of the same page are set up and run live at the same time, and human users are redirected to a random one. Changes are made only to the variant pages, and data collected are compared to a previously determined performance forecast.


In SEO A/B testing, as we have seen, pages are split into two sets-controls and variants. CRO aims to improve the conversion rate once visitors have reached the site SEO focused testing aims to increase the number of visitors to the site, by implementing technical changes that will improve the website’s position in the SERPs. Aims and ObjectivesĪlthough CRO and SEO testing both use A/B testing, their goals – and how they are carried out – are very different.

The Differences Between A/B Testing for SEO Versus CROĪ/B testing for SEO is a bit different than what we would do for conversion rate optimization or user experience testing. In this part, we’ll aim to shed light on each technique, how they differ, and what they’re used for. SEO A/B testing is the optimization of web page elements through before and after testing. The goal of SEO split testing is to get more people to click on your link in Google’s search results and visit your site.
