How to use
- Choose the calculation base and the types of interactions.
- Enter the metrics of a single post or upload a table of a series.
- Check the counted rows and save the calculation together with the formula.
How it works
ER = selected interactions / selected base × 100%. In a series, the overall metric divides the sum of interactions by the sum of the base, while the average of percentages gives each post equal weight. A row with an unknown action or a zero base does not participate in the totals. An empty field means no information is available, 0 means a known absence of actions.
Example
Training example: 45 reactions and 5 comments with 1 000 followers give 5%. If the same post got 2 000 views, the ER by views equals 2,5%. These results answer different questions; actions are not equal to unique people.

Questions about the tool
What ER is considered good?
There is no universal norm. Compare one platform, format, set of actions, and time period after publication. The metric does not confirm the quality of the audience or future sales.
Is this ERR from Telegram statistics?
Here the numerator is the selected interactions. The ratio of views to subscribers is a different metric. When comparing services, first verify their definitions.
