Follower-based engagement
Useful when comparing account-level performance or sponsorship positioning, because the denominator stays tied to audience size.
Glossary
Creator metrics glossary
A compact reference for the metrics that show up in creator dashboards, sponsorship conversations, and the calculators on this site.
Quick definitions
| Metric | Plain-English meaning | Simple formula or note |
|---|---|---|
| Engagement rate | How much interaction a post generated relative to a chosen audience base. | (Likes + comments + shares + saves) divided by followers or views, then multiplied by 100. |
| CTR | How often people clicked after seeing the content package. | Clicks divided by impressions. Often used for thumbnails, titles, and ad creative. |
| RPM | Revenue earned per thousand views after platform-specific adjustments. | Total revenue divided by views, then multiplied by 1000. |
| CPM | Cost or revenue basis per thousand impressions before some downstream adjustments. | Used by advertisers and publishers, but not always the same as RPM. |
| Average view duration | How long, on average, a viewer stayed with the video. | Total watch time divided by total views. |
| Retention | How much of the video people kept watching over time. | Usually shown as a curve rather than a single number. |
| Saves | A signal that a viewer wants to come back to the content later. | Often useful for educational, checklist, and reference-style content. |
| Shares | A signal that the content was strong enough to pass to someone else. | Helpful for measuring portability and audience advocacy. |
When the denominator changes the story
View-based engagement
Useful for individual videos, especially on platforms where distribution often reaches beyond existing followers.
Impression-based rates
Useful when judging packaging efficiency. If impressions are high but CTR is weak, the title or thumbnail may need work even if the topic itself is good.
What these metrics can miss
No single metric explains whether a piece of content was worth making. A post can have a high engagement rate and still attract the wrong audience. A video can have weak CTR but produce strong downstream conversions. That is why this site favors transparent single-purpose tools instead of pretending one score can summarize every creator workflow.
Why can a "good" engagement rate still be misleading?
Small audiences often produce stronger percentages, while larger accounts may produce lower percentages with much larger total business impact. The denominator always matters.
Is RPM the same on every platform?
No. RPM can include different platform deductions, revenue sources, and reporting rules. Use it for planning inside a platform context, not as a universal creator income number.
