- Cost per Engagement = Ad Spend ÷ Total Engagements
Use reach when you want exposure-based performance, followers for audience-size benchmarking, impressions for frequency-heavy campaigns, and views for video-first content analysis.

Frequently Asked Questions
1. What is post engagement rate?
Post engagement rate measures how actively people interact with a post compared with a base such as reach, followers, impressions, or views.
2. Which base should I use?
Use reach for exposure efficiency, followers for audience benchmarking, impressions for repeated delivery campaigns, and views for video content where play volume matters most.
3. Why include saves and shares?
Saves and shares often signal stronger intent than likes. They suggest content usefulness, advocacy, or future reference, so many teams weight them more heavily.
4. What is weighted engagement rate?
Weighted engagement rate applies custom importance values to each action. It helps reflect business goals when comments, follows, or clicks matter more than passive reactions.
5. Can I compare different platforms?
Yes, but compare carefully. Platform behavior, feed design, audience intent, and content format can change average engagement patterns significantly.
6. Is a higher engagement rate always better?
Usually yes, but context matters. Small audiences, boosted posts, giveaways, and controversial topics can distort rates without indicating better long-term content quality.
7. What does cost per engagement show?
Cost per engagement estimates how much you spent for each interaction. It is useful for paid campaigns, budgeting, and testing creative efficiency.
8. Why do my rates change by method?
Each method uses a different denominator. A post can look stronger by reach and weaker by followers, depending on delivery scale and audience size.
