Social Media Analytics
Part of the Digital Marketing Roadmap
In short
Likes feel nice, but they don't tell you if social media is working. Analytics shows which posts reach new people, spark conversations, and send visitors to your site.
Tracking reach, engagement rate, follower growth and (critically) click-throughs or conversions from social — going beyond vanity metrics to understand what's actually driving business results.

Think of it like this
A cricket scorecard
A scorecard doesn't just show the total. It shows who scored, strike rates, and who got out cheaply. That's how a coach picks the next team. Social analytics is your scorecard for posts.
Watch it happen
From reach to results for one month

The big ideas
What you need to know
Reach and impressions
Reach is unique people. Impressions count every view, including repeats.
Engagement rate
Engagements divided by reach or followers. Pick one method and stick to it for fair comparisons.
Saves and shares
These often say more about value than likes do.
Clicks to your site
Use UTM links so GA4 shows which posts and platforms drove visits and sign-ups.
See it in code
Walk through the code
1=SUM(C2:F2)/B22=AVERAGEIF(G2:G30,"Reel",H2:H30)3=LARGE(H2:H30,1)1/3Engagement rate by reach for one post.
B is reach, C to F are likes, comments, shares and saves, G is format, H is engagement rate from the first formula.
Save yourself the pain
Common mistakes
Oops
Comparing your engagement rate with a celebrity's.
Do this instead
Compare with your own past months and similar-sized accounts in your niche.
Oops
Reporting likes as the main result.
Do this instead
Lead with reach growth, saves, shares, link taps and sign-ups, then likes.
Your mission
Score your own posts
