Calculating Your Projected Engagement

The projected engagement rate is calculated by applying your Engagement Uplift Goal to your current performance. This allows you to set a tangible goal for your Hashtag Optimization Strategy. If your Current ER is 3.5% and your Goal is 30% Uplift, your Projected ER will be 4.55%.

The formula for the Projected Engagement Rate is:

$$\text{Projected ER} = \text{Current ER} \times \left(1 + \frac{\text{Uplift Goal}}{100}\right)$$
