The lesson

Every platform offers free insights: reach (how many people saw a post), impressions (how many times it was seen), engagement (likes, comments, shares, saves) and clicks.

Engagement rate makes posts comparable: total engagements divided by reach, times 100. A post with 50 engagements from 1,000 people reached (5%) performed better than one with 80 from 4,000 (2%).

Look for patterns rather than single numbers: which pillars, formats and posting times perform best over several weeks?

Step by step

  1. Collect reach and engagement for ten posts.
  2. Calculate each post's engagement rate.
  3. Identify the best and worst posts.
  4. Write down what the best posts have in common.
Worked calculation

Which post really performed better?

Comparing posts fairly with engagement rate instead of raw likes.

Difference5.0% − 2.0%Post A +3.0 points

Explanation

Post B has more likes in total, but it was shown to four times as many people. Engagement rate removes the effect of reach, so posts can be compared fairly.

Post A's audience responded more than twice as strongly, which suggests product videos deserve more effort — worth testing over several weeks before deciding.

Check your understanding

A third post had 45 engagements from a reach of 1,500. What is its engagement rate? (45 ÷ 1,500 × 100 = 3.0%.)

Practice activity

From a provided insights screenshot set, calculate engagement rate and identify the best and worst posts with reasons.

Expected result: Correct calculations and a reasoned best/worst post comparison.

  1. What is a vanity metric?

    Show answer

    A number that looks impressive (like likes or follower count) but doesn't show business results.
