New Subscribers Over Time

1 views 0

By default, the New Subscribers Over Time section shows your new subscriptions over the last 90 days.

You can also use this section to compare data year-on-year. This means that you can examine the seasonal trends in the subscription patterns and how your business grew this year compared to last year.

You can focus on a specific period by dragging the ends of the slider beneath the graph, as illustrated below:

When the date axis becomes a dotted line, the data shows a forecast for the next 30 days. The forecast is based on your current subscriber trajectory and assumes that you have not changed anything in your set up, such as changes to rules or starting a new campaign. If you hover over this area, you can see the following information based on your data and the date that the forecast covers:

  • Forecast value

    The forecast value shows the forecasted number of subscribers for the forecast period based on your current data.

  • Upper bound

    The upper bound shows the highest number of subscribers that you can expect to gain during the forecast period based on your current data.

  • Lower bound

    The lower bound shows the lowest number of subscribers that you can expect to gain during the forecast period based on your current data.

  • Confidence level

    The confidence level

    • For example, in the following illustration, the forecast predicts that the company will have 43 subscribers on the 14th October, with an upper bound of 48 customers and a lower bound of 37 customers and a confidence level of 80%:

      You can use this data to project how your subscription growth is likely to move over time. This information can then be used to adjust your user journeys and product offerings to maximise your subscriptions.
