What is Delta?
“Delta” is a term used to describe the difference between two values or metrics over a period of time. In the context of conversion rate optimization, delta is used to measure the change in conversion rates between two different versions of a website or a specific element on a website.
For example, let’s say you have two versions of a website’s landing page: Version A and Version B.
Version A has a conversion rate of 5%, while Version B has a conversion rate of 7%. The delta between the two versions would be 2%, which represents the increase in conversion rate from Version A to Version B.
Delta is an important concept in conversion rate optimization because it allows marketers and website owners to measure the impact of changes made to a website or specific element on the website. By calculating the delta between different versions, it’s possible to determine which version is performing better and which changes should be made in order to optimize conversion rates.
When running A/B tests or multivariate tests, the delta is used to determine statistical significance, which is the likelihood that the difference in conversion rates between two versions is not due to chance. A statistically significant delta indicates that a change made to a website or specific element had a measurable impact on conversion rates.
Delta is a key concept in conversion rate optimization that measures the difference between two values or metrics over time. It’s used to determine the impact of changes made to a website or specific element and is a crucial factor in running effective A/B tests and multivariate tests.
