Companies whose conversion rates have improved carry out 50% more tests on their websites than companies whose conversion didn’t improve. However, 7% are testing nothing at all. 

This difference is even more apparent when looking at sales. Companies with a large increase in sales carried out over two times as many tests as the average. 

Of the companies that carry out testing, 60% carry out one or two A/B multivariate tests a month and only 6% perform more than 10 tests a month.

These findings come from the fifth annual Conversion Rate Optimisation Report, carried out in partnership with RedEye, and based on a survey of almost 1,000 client-side and agency digital marketers.

Let’s take a look at what areas & elements our respondents are testing and what they find to be the most challenging stages.
