In ilo, “EPI” stands for “Engagements per Impression”.
EPI is a very useful base metric to gauge how well a tweet performs.
EPI measures total engagements relative to the number of times a tweet is viewed, making it easy to compare engagement levels of different tweets regardless of how many impressions they get.
For account below 20,000 followers, here is a helpful scale for different EPIs.
- a great EPI is typically 5% or higher
- a good EPI is 3–5%
- an OK EPI is 1–3%
- a poor EPI is less than 1%
This means a really well-performing great tweet typically gets 1 or more engagements per 20 views.
