| Metric | Formula |
|---|---|
| Total Engagements | Likes + Comments + Shares + Saves + Clicks + Replies + Mentions + Story Interactions + Custom Engagements |
| Engagement to Reach Ratio | (Total Engagements ÷ Reach) × 100 |
| Weighted Engagements | Σ(Each Interaction Count × Its Weight) |
| Weighted ERR | (Weighted Engagements ÷ Reach) × 100 |
| Engagement Rate by Impressions | (Total Engagements ÷ Impressions) × 100 |

Frequently Asked Questions
1. What does engagement to reach ratio show?
It shows how many interactions were generated compared with the number of unique people reached. It helps evaluate content efficiency more fairly than raw engagement totals alone.
2. Why use reach instead of impressions?
Reach counts unique accounts, while impressions can include repeat views from the same person. That makes reach-based engagement better for judging audience response quality.
3. What actions should count as engagement?
Most teams include likes, comments, shares, saves, clicks, replies, and similar platform actions. The calculator also supports custom engagements for network-specific signals.
4. Should every interaction have the same weight?
Not always. A share or comment may signal more intent than a like. Weighted scoring helps align the report with your campaign goals.
5. What is considered a good ratio?
There is no single universal benchmark. Performance differs by platform, audience size, content format, industry, and paid support. Compare similar campaigns and track trend movement.
6. Can paid promotion affect the ratio?
Yes. Paid reach can expand exposure faster than engagement grows, which may lower the ratio. Benchmark paid and organic content separately for cleaner analysis.
7. Why compare by posts analyzed?
Average engagement per post helps normalize totals when one campaign includes many posts and another includes only one or two. It improves campaign-to-campaign comparison.
8. When should I use the benchmark field?
Use it when you already track a target ratio for a platform, content pillar, or reporting period. It helps quickly show whether current performance is above or below target.
