The main methodologies we use for CRO

Browser mit Checkliste und Lupe - Digitalagentur SUNZINET
Behavioural pattern analysis

We utilize consumer psychology tools, such as 7-level analysis, to help businesses understand customer interactions and make data-driven strategic decisions.

Behaviour pattern analysis involves observing customer interactions with products, services, or digital platforms to gain insights into their needs, motivations, and preferences. This valuable information guides marketing strategies, product development, and overall business decision-making.

A/B Tests

A/B testing is a methodology used to compare two versions of a web page, email, or app to determine which one performs better in terms of user engagement and conversions.

Using this methodology means we first identify a hypothesis, create two variations (A and B), divide the audience into two groups, present each group with one variation, collect data on user behaviour, and analyse the results to determine the winning variation.

A/B testing is beneficial as it provides data-driven insights, allows for evidence-based decision-making, improves conversion rates, enhances user experience, and helps optimize digital assets for better business outcomes.
