Social Media Metrics: The 15 That Matter and How to Track Them

AnalyticsBy the Pixtale Growth team · 9 November 2026 · 9 min read

Every platform gives you dozens of numbers, and most of them don't change what you do next. This guide covers the 15 social media metrics that do, grouped by what they tell you, with the formula for each, how to measure social media success in Google Analytics, and how to pick the few KPIs that fit your goal.

Metrics vs KPIs: what's the difference?

A metric is any number a platform reports: views, likes, follows, clicks. A KPI (key performance indicator) is one of those metrics that you have chosen because it shows whether you are reaching a goal. A coffee shop that wants more visitors might track a dozen social media metrics but only three KPIs: reach in its city, saves on menu posts and direction requests.

So start with the goal, then choose the metrics. The rest of this guide groups the useful metrics by the goal they measure.

Awareness metrics: are new people seeing you?

1. Reach. The number of unique accounts that saw your content. It is the best single measure of how far a post travelled. Compare reach with your follower count: when reach is higher than your followers, the platform is showing you to new people.
2. Views (impressions). How many times your content was shown or played, counting repeat views. Instagram now reports views as its main number for reels, posts and stories, where it used to show impressions. Views are always higher than reach.
3. Follower growth rate. How fast your audience is growing, which is fairer than a raw follower count when you compare months or accounts.
   Formula: (followers gained in the period ÷ followers at the start) × 100. Example: 150 new followers on a base of 5,000 is a 3% monthly growth rate.
4. Non-follower reach. The share of your reach that came from people who don't follow you yet. Instagram shows this in Insights for each reel and post. A high share means the content is being recommended.

Engagement metrics: do people care?

5. Engagement rate. The most compared number in social media, and the easiest to calculate in different ways.
   By followers: (likes + comments) ÷ followers × 100.
   By reach: (likes + comments + saves + shares) ÷ reach × 100.
   Use one formula and stick to it so months stay comparable. Our free engagement rate calculator uses the follower method and shows how you compare with accounts your size. For benchmarks, see what a good Instagram engagement rate is.
6. Saves. People keep the post to come back to it. Saves are one of the strongest signs that content is useful, and they matter more than likes for tips, recipes and checklists.
7. Shares. People sending your content to friends or to their stories. Shares bring in new viewers directly, so they are the engagement metric most tied to growth.
8. Comments. Count them, but also read them. Ten real questions are worth more than a hundred emoji replies, and they are free ideas for your next posts.
9. Average watch time and retention. For reels and videos: how long people watch, and where they drop off. If most viewers leave in the first two seconds, fix the hook before anything else. Our list of reel hooks helps.

Traffic and conversion metrics: does it bring business?

10. Profile visits. How many people tapped through to your profile. It sits between seeing a post and following or buying.
11. Link clicks and click-through rate (CTR). Clicks on your bio link, story links or ads.
    Formula: clicks ÷ reach (or views) × 100. Example: 80 clicks from a story seen by 4,000 accounts is a 2% CTR.
12. Website sessions from social. The visits your site gets from social platforms, measured in your analytics tool rather than in the app. More on this below.
13. Conversions and conversion rate. Sign-ups, enquiries, orders or bookings that came from social.
    Formula: conversions from social ÷ sessions from social × 100.

Community and care metrics: how do people feel?

14. Response time. How quickly you answer comments and DMs. For a business, a fast reply often decides whether a question turns into a sale.
15. Sentiment. Whether comments and mentions are positive, neutral or negative. You don't need a tool for this at first: once a month, read the latest 50 comments and mark each one.

Which KPIs to pick for your goal

Pick three to five, not fifteen. These combinations work for most accounts:

• Grow the audience: reach, non-follower reach, follower growth rate and shares.
• Build a loyal community: engagement rate, saves, comments and response time.
• Get leads and sales: profile visits, link clicks, website sessions from social and conversions.
• Creators working with brands: engagement rate, average views per reel, audience location and follower growth rate. These are the numbers brands ask for first.

If you run several accounts or work for clients, keep the same KPIs in every monthly report so the trend is easy to read. Our guide to Instagram reports for clients shows a simple layout.

How to measure social media success with Google Analytics

Platform insights tell you what happened inside the app. Google Analytics 4 (GA4) tells you what those visitors did on your website, which is where most sales happen.

1. Tag your links with UTM parameters. Add utm_source (for example instagram), utm_medium (social) and utm_campaign (for example diwali-sale) to every link you share. Without them, many app visits show up as direct traffic. Google's free Campaign URL Builder creates these links for you.
2. Open the traffic report. In GA4 go to Reports, then Acquisition, then Traffic acquisition. Look at the Organic Social channel, or change the table to show session source and medium to see each platform and campaign separately.
3. Mark your key events. In GA4, the actions that matter (a purchase, a form sent, a sign-up) are called key events. Mark yours in the Admin settings so the reports show how many came from social.
4. Compare month on month. Sessions, engaged sessions and key events from social are the three numbers to put in your report.

Metrics by platform

• Instagram: views, reach, non-follower reach, saves, shares, profile visits, link taps and reel watch time, all in Insights for professional accounts. To see the same public numbers for any account, including competitors, check a profile on Pixtale.
• YouTube: impressions click-through rate (how often a thumbnail gets clicked), average view duration, returning viewers and subscribers gained per video. Our free YouTube channel analyzer shows a channel's best videos and upload rhythm.
• Facebook: reach, engagement, link clicks and video retention in Meta Business Suite.
• LinkedIn: impressions, engagement rate, follower demographics and clicks on company page posts.
• TikTok: video views, average watch time, watched full video and traffic source (For You feed vs profile vs search).

Vanity metrics to watch with care

Follower count and likes feel good but say little on their own. A large account with low reach and no clicks is worth less to a business than a small account whose posts are saved and shared. Follower counts can also be inflated by inactive or fake accounts; our guide to checking fake followers explains how to spot them.

A simple monthly metrics routine

1. On the first of each month, write down your three to five KPIs for last month next to the month before.
2. List your top three and bottom three posts by your main KPI, not by likes.
3. Write one sentence on what the top posts have in common: format, topic, hook or posting time.
4. Choose one change to test next month, and only one, so you know what made the difference.

Fifteen minutes a month is enough. The habit matters more than the tool.
