Wikipedia defines it in the following way – “Conversion optimization, or conversion rate optimization (CRO) is a system for increasing the percentage of visitors to a website that convert into customers, or more generally, take any desired action on a webpage. It is commonly referred to as CRO".
In its simplest form it is all about improving website performance. The most used term with CRO is probably A/B testing, but this only represents a small amount of what is involved in a CRO program. The Kraken Data program encompasses the study of analytics and website visitor behaviour to identify areas for testing. We then create strategies and hypotheses that we use to get statistically significant results.
A new user is identified by Google as someone who lands on your site and does not have the Google Analytics cookie in the browser they are using. This could be for a number of reasons:
- They are actually first time visitors
- They have visited before but deleted the GA cookie
- They visited before but on a different browser (i.e. This time Chrome, last time Firefox)
Returning visitors are identified because they have the GA cookie present, this allows GA to use the Client ID for analysis.
For reporting it is important to remember that visitors can be both new and returning depending on the period chosen. If someone visits on Day 1 and then revisits on Day 2, you would see one new visitor for Day 1 and one returning visitor for Day 2. If we look at a time period that includes both days we would see one new and one returning visitor, but we would only see one “user” for that period.
Sometimes it just seems too hard, you are almost literally hitting your head against a brick wall.
In these cases the best way to convince stakeholders and grab their attention is simply to demonstrate the economic impact achievable by moving down the optimisation path.
A table like this shows the effect on the bottom line for the business.

In simple terms, one-tailed (or one-sided) tests will only tell you if control is equal to the variant or not. If control is not equal to the variant it could mean that control is better than the variant or vice versa. Two-tailed (or two-sided) tests also identify if control is different to the variant, with the addition of whether variant or control is the better performer.
For A/B tests this is particularly important as the lift or otherwise is not known prior to the test starting.
CRO (Conversion Rate Optimization) and UX (User Experience) are related but distinct fields that focus on different aspects of the user’s interaction with a website or app.
CRO is focused on increasing the percentage of visitors to a website or app who take a desired action, such as making a purchase, filling out a form, or signing up for a newsletter. CRO involves data-driven techniques for improving website or app performance, such as A/B testing, heat mapping, and user surveys, to understand how users interact with a website and make changes to increase conversion rates.
UX, on the other hand, is focused on the overall experience that a user has with a website or app, and aims to make the experience as smooth, intuitive, and satisfying as possible. UX encompasses many aspects of the user experience, such as ease of use, accessibility, and visual design, and is focused on improving the overall user experience and making it as user-friendly as possible.
While CRO and UX both have the same goal of improving the user experience, they approach this goal from different angles, with CRO focused on increasing conversion rates and UX focused on improving the overall user experience.
