Audience growth rate is a key social media metric that measures the rate at which a brand or business gains new followers over a specific period. Rather than simply tracking the total number of followers, this metric provides insight into how quickly an audience is expanding in relation to the brand’s existing following.
By analysing audience growth rate, businesses can evaluate the effectiveness of their marketing strategies, identify trends in audience engagement, and make data-driven decisions to optimise their content. A steady or increasing growth rate suggests successful audience attraction, while a stagnant or declining rate may indicate the need for strategy adjustments.
How to calculate audience growth rate
Formula:
New followers in a given period ÷ Total followers at the start of that period × 100
Example:
If a brand starts the month with 5,000 followers and gains 500 new ones, the audience growth rate would be:
500 ÷ 5000 × 100 = 10%
