15 Social Media KPIs That Matter (And How to Track Each One)

What does “success” even mean on social media?
Let’s start here.
Because chasing likes, follows, and views can feel like sprinting on a treadmill—motion without direction. The dopamine is real, but so is the burnout. If you’re trying to grow, not just post, you need something sturdier than vibes.
You need KPIs for your social media platform.
But not the ones everyone talks about. Not just the vanity numbers.
The ones that actually tell you if your strategy is working.

What Are Social Media KPIs, Really?
KPI stands for Key Performance Indicator.
Not all metrics are KPIs.
A KPI is something that signals movement toward your goal, whether that goal is growth, trust, engagement, or sales.
In other words:
KPIs are not about what happened. They’re about what mattered.
Start With Your Goal, Not Your Feed
Too many creators and brands ask:
“How’s my Instagram doing?”
The better question:
“What is Instagram supposed to be doing for me?”
Three common goals:
- Build awareness
- Drive engagement
- Generate conversions
Each demands different KPIs.
Let’s Break Down the KPIs by Objective
1. If You’re Building Awareness
Your north star is visibility. Not just showing up, but showing up in front of the right people.
Track these KPIs:
- Reach: Unique viewers. This tells you how far your content spreads.
- Impressions: Total views. High impressions with low reach = same people seeing it again and again.
- Follower Growth Rate: Not just how many, but how fast.
- Brand Mentions (tagged or untagged): Are people talking about you, even when you’re not in the room?
How to track:
- Use native analytics (Instagram Insights, X / Twitter Analytics, TikTok Pro)
- Set Google Alerts or use a tool like Brand24 for mentions
- Track week-on-week or campaign-specific spikes, not just monthly aggregates
Growth isn’t about going viral once. It’s about expanding your radius steadily.
2. If You Want Engagement That Sticks
You’re not just talking—you want a conversation.
Track these KPIs:
- Likes: The number of times followers engage with a social post by clicking the Like button on a specific social media platform
- Comments per Post: A “like” is passive. A comment is a commitment.
- Saves: Quietly powerful. If they’re saving it, it resonated deeply.
- Shares: The truest form of “this is worth your time.
- Engagement Rate (by Reach or Total Follower): [(Likes + Comments + Shares + Saves) / Total Followers] × 100”
This metric calculates the total engagement a post gets—likes, comments, saves, and shares—divided by your total follower count or reach. It reflects how engaging your content is on average. - Clicks: How many times do users click the link in your post?
How to track:
- Instagram/TikTok give these in the backend per post
- Use tools like Later, Metricool, or Buffer for long-term trendlines
- Benchmark against your own average—your real competition is you last month
True engagement is when the content moves with your audience, beyond the feed.
3. If Your Goal Is Conversions
Clicks, signups, sales.
This is where performance gets real—and messy.
Track these KPIs:
- Click-Through Rate (CTR) on links in bio/stories/posts
- Conversion Rate: Visitors who actually take action
- Cost Per Acquisition (if you’re running ads)
- Revenue per Post or Campaign
- Bounce Rate: Not everyone who clicks a link in your social post will stick around to read the full article or make a purchase.
Bounce rate measures the percentage of people who clicked but left the page without doing anything. A high bounce rate usually means the page didn’t meet their expectations.
How to track:
- UTM-tag every campaign link (use Google’s Campaign URL Builder)
- Connect platforms like Instagram or TikTok to Google Analytics 4 (GA4)
- Set up Goals or Events in GA4 to track exactly what matters—downloads, signups, purchases
Social media doesn’t close the sale. But it opens the door—and your KPIs tell you if they walked through it.
How to Choose the Right KPIs (Without Losing Your Mind)
There’s no universal dashboard.
But there is a universal principle:
Every KPI should answer: “Are we moving toward the result we care about?”
Here’s how to make it practical:
One option: Create a Social Media KPI Matrix
- List your channels (IG, TikTok, X, etc.) horizontally
- List your goals (Awareness, Engagement, Conversion) vertically
- Choose 1–2 key metrics per box. Keep it lean. Keep it actionable.
The second option: Use the “3R Rule”
- Reach metrics for top-of-funnel (audience building)
- Resonance metrics for middle-of-funnel (community building)
- Response metrics for bottom-of-funnel (revenue-building)
Good KPIs Don’t Just Report—They Inform
Metrics that sit in spreadsheets aren’t useful.
Metrics that shape what you post next are.
Here’s what that looks like in practice:
If your “Shares” spike on carousel posts, double down on them next month.
If your “Saves” drop on Reels, check if the content still teaches or inspires.
If your “Click-throughs” flatline, test new CTAs or placement.
Your audience is speaking. KPIs are just the transcript.
Examples in the Wild
Let’s get specific.
- A fitness creator sees their Reels getting 50K views but only 2% follower growth.
That’s reach without resonance.
-> They test story polls to invite more interaction and see comments double. - A skincare brand gets tons of likes on aesthetic flat lays. But saves and shares spike only on how-to videos.
-> They shift their ratio to 70% educational content, 30% aesthetic. - A coach links a new freebie in their Instagram bio. The post gets 300 likes, but only 6 clicks.
-> They rewrite the caption with a bolder CTA—next post: 312 likes, 45 clicks.
See the pattern? The KPI isn’t the end. It’s the feedback loop.
