AB testing has benefited my organisation, due to being able to run AB tests for our clients, the basis of our CRO offering. However, testing hundreds of changes simultaneously through multivariate testing has not benefited my organisation particularly, due to the difficulty we found in setting up multivariate tests. The test took a disproportionate amount of time to set up, needing lots of developer resource so costing a lot. Tracking conversion goals via VWO can be tricky, as they can be difficult to set up, so we prefer to use GA to track the results of the test. We also find GA to show more accurate results. Likewise, due to not using VWO to track conversion goals, we use third party tools for understanding the statistical validity of results.
