Audience Growth Rate

Audience Growth Rate (AGR) is a measure of how rapidly an eCommerce platform expands its user base over a particular period of time.

In the field of eCommerce, the Audience Growth Rate is a key performance indicator that determines the pace at which the customer base of an online business is expanding. This figure is calculated over a specific period (monthly, quarterly, annually, etc.) and reveals essential information about the effectuality of the business's marketing and retention strategies. Growth in audience suggests that the business is effectively promoting its products or services, attracting new customers, and retaining existing ones.


Audience Growth Rate = ((Number of Audience at the end of the period - Number at the beginning) / Number at the beginning) * 100.


An online store has an audience base of 10,000 customers at the start of June and sees an increase to 15,000 by the end of the month. The formula indicates a growth rate of 50%.

Why is AGR important?

Audience Growth Rate is vital as it allows online businesses to track and analyze the effectiveness of different promotional strategies, marketing campaigns, and customer engagement initiatives over a defined period. This percentage enables the business to accurately gauge its progress towards its objective of increasing brand visibility and engagement, and thus, revenue.

Which factors impact AGR?

The factors impacting the Audience Growth Rate range from the effectiveness of marketing campaigns, state of customer service, product quality, price competitiveness, to the usability of the website/app. Economic conditions and market shifts also play a role in fluctuation in audience size.

How can AGR be improved?

  • Properly designed and targeted marketing campaigns
  • Regular engagement with current customers using personalized content and offers
  • Excellent customer service to increase customer retention
  • Using audience data to understand customers’ buying behavior and tailor offerings

What is AGR's relationship with other metrics?

Audience Growth Rate co-relates with various eCommerce metrics like Customer Acquisition Cost (CAC), Customer Lifetime Value (CLV), and Return on Advertising Spend (ROAS). For instance, a high AGR, coupled with a lower CAC, indicates effective marketing strategies. A steady AGR with a high CLV suggests a healthy customer retention rate.
