## Definitoin of Stickness Stickiness is a [[Product Metric]] that measures the extent to which users are engaged with a product or service. It is essentially a measure of how “sticky” a product or service is for its users. Stickiness is a measure of [[Product Growth/User Engagment/Customer Engagement]]and [[Customer Loyalty]], and it is often used to determine the success of an online product or service. ## Stickness Formula & Calculation The formula for calculating stickiness is as follows: > Stickiness = (Daily Active Users/Monthly Active Users) x 100 In this formula, Daily Active Users ([[Daily Active Users (DAU)]]) is the number of unique users who visit the product or service within a day and Monthly Active Users ([[Monthly Active Users (MAU)]]) is the number of unique users who visit the product or service within a month. For example, if a product or service had 1,000 DAU and 10,000 MAU, the stickiness score would be 10%. This indicates that 10% of the total monthly user base visits the product or service each day. A higher stickiness score would indicate higher engagement and loyalty, while a lower stickiness score would suggest that users are not as engaged or loyal to the product or service. !![[Note Name]]
