Regardless of the type of test we run, the runtime is unknown and depends on two things: the number of users and the amount of variation change. Some tests take days, and others take months. The hypothesis should be thoroughly researched to speed up the testing time. Also, they should provide a big enough change, compared to the current site, to make a difference in the outcome. In addition, the more traffic we have, the more users can add data to the test, so it concludes faster.

No, the A/B tests run on the same URL, and any changes to the variation are fast, so no content is duplicated. Google also has its A/B testing platform, which wouldn’t exist if testing affected organic rankings. If we run an A/B test on a different URL, we can run into problems because split URL tests require different URLs. For example – and On the new URL, we should add a canonical tag (rel=canonical href=“″) so that the bots know which version to index. As part of our consultancy service we offer full advice on the technical constraints of your site.

A successful variation is measured against the base version of the site using a Bayesian methodology. This method represents the update of the probability that a variation will succeed or fail as more data becomes available (for example, more users pass the test). The number we are looking to achieve is 90% statistical significance, so we are 90% sure that the new version will perform better than the base version.

CRO testing software means that additional JavaScript is added to your website. However, it’s usually loaded asynchronously, meaning it doesn’t block the download of other assets in the browser or the rendering of elements that your clients can see. As part of HOLD Marketing’s CRO offering, we also perform speed audits to optimize your site so that it loads as quickly as possible
