John Wanamaker (1838-1922) was considered by some to be a “pioneer in marketing.”

He is credited with coining the phrase:

“Half the money I spend on advertising is wasted; the trouble is, I don’t know which half.”

If he were marketing today, then he’d know precisely where his money and efforts were being rewarded and wasted, thanks to the plethora of available metrics.

Social media KPIs allow you to address this conundrum and focus your efforts on the marketing strategies that work for your brand.

In this guide, you’ll discover:

  • Why your brand needs to track social media KPIs
  • Which social media KPIs are relevant to your goals
  • How to set up and track your social media KPIs

Let’s start!

Manage all your social media accounts in one place.

Craft, schedule, & auto-post content to all your social channels, then track analytics and manage interactions from a single, easy-to-use dashboard.

What is a Social Media KPI?

KPI stands for Key Performance Indicator.

Businesses use KPIs to measure performance over time, track if they’re meeting goals, and evaluate whether changes are needed. Each business function has different KPIs to measure its goals.

Even marketers have different KPIs depending on the campaign, platform, and marketing channel they’re using. For example, social media KPIs will differ from those needed for PPC advertising.

A social media KPI is a metric used to measure content performance versus goals and determine if a company’s social media marketing strategy is working.

Why Your Brand Should Track Social Media KPIs

There are several benefits of tracking social media KPIs, such as measuring performance, surfacing insights, and driving continuous improvement.

By tracking specific metrics, you’ll know if your social media strategy is working and your brand is achieving its business goals.

There are lots of social media KPIs you could use. But the key is choosing those that are relevant to your specific goals.

For example, say your business wanted to build brand awareness and reach more of your ideal customers. Then your Instagram goal might be to increase followers, and your KPI might be to increase the number of Instagram followers by 5% in Q1. In other words, you’ve applied a specific target and measure for the goal.

Let’s look at some more social media KPIs that might be relevant to you.

Which Social Media KPIs are Relevant to Your Goals?

With so many possible social media KPIs to track, it’s essential that you choose the ones that match your goals. And given that goals vary from campaign to campaign, it’s not simply a case of picking a few now and forgetting about the rest. Instead, you’ll have to re-evaluate each time.

The following list of social media KPIs is not platform-specific – we’ll look at those in the next section. These KPIs are listed by business goals, such as reach, engagement, lead generation, conversions, and customer loyalty.

Social media KPIs for reach

Reach KPIs measure how many people come across your social media accounts and posts. Reach is a quantity metric that shows your existing and potential audience, growth over time, and brand awareness.


The number of followers your social media account has at a set time.


The number of times your post or account/profile has been seen.

Note: This doesn’t necessarily mean the person who saw the post noticed it or read it. And it doesn’t distinguish between individual accounts. It only totals up the views. So one person could see the same post in their feed three times, which means three impressions.

Post reach

The number of individual accounts that saw your post.

In the previous example, when one person saw the same post three times, the post reach was one. So post reach is usually lower than impressions.

Post reach varies depending on when your audience is online and how good your content is. But it’s a good indication of what your audience finds valuable and interesting.

Here’s how to calculate post reach:

Post Views / Total Followers x 100 = Post Reach Percentage

Share of voice

Your share of voice (SOV) shows how much visibility you have online compared to your competitors. In social media, it’s measured by brand mentions – i.e. the number of times your brand is mentioned compared to the number of times your competitors are mentioned.

Here’s how to calculate social media share of voice:

Brand Mentions / Total Mentions x 100 = SSoV Percentage

Web traffic

Web traffic shows you how well your social media posts with links to your website are performing.

It’s usually tracked in Google Analytics (or other analytics platforms) with UTM parameters. It shows the number of times someone clicked from your social media account to get to one of your website pages.

Social media KPIs for engagement

Engagement KPIs measure how your audience is interacting with your brand, and it’s one of the most important social media metrics. Reaching thousands of people counts for nothing if they don’t show any interest in what you have to offer.

Simply put, engagement measures the amount of likes, shares, and comments that your content receives.


The number of times people interact with a social post by clicking the “Like” button. Likes are often considered to be a “vanity metric” as they are the lowest form of interaction on a platform and don’t show any significant type of intent.

However, you can still use them to inform decision-making on aspects like content creation and content curation.

Some platforms, such as Instagram and Facebook, are now hiding the “Like” count from public view, but you can still see these metrics in your analytics.


While Likes can be a passive or mindless action, Shares are more deliberate. They show the next level of engagement – someone liked your post enough to want to share it with friends. A high share count reflects the quality of your work and can indicate how viral a post is.

Note: Shares have different names on different platforms:

  • On Pinterest, it’s a Repin.
  • On Twitter, it’s a Retweet.
  • On Instagram, it’s the use of the share icon to either DMs or a Story.


The number of times people comment either positively or negatively on your posts Receiving comments is another indicator that your content is on track. And it’s an excellent way to continue a conversation with your audience.


Mentions are when someone tags your account or mentions your brand. It can happen in a post, in a comment, in a story, or in a direct message.

You can track Mentions and view conversations containing your brand name with social listening software, such as Mention.


In the past, Clicks were a measure of how many times a link in a post was clicked. Now, Clicks also refer to the number of times a person clicks to read more, i.e. expands the caption to read more.

Social media KPIs for conversions

Conversion KPIs measure how many social interactions convert into desired actions, like website visits, newsletter sign-ups, or purchases. They reflect how effective your social media strategy is and whether it’s leading to actionable outcomes.

Conversion rate

The number of users who perform the actions described in your CTA (Call to Action) compared to the total number of clicks on that given post. For example, how many people visited your website or landing page, subscribed to your mailing list, or made a purchase after clicking the CTA.

A high conversion rate indicates that your social media post was valuable to your audience and made them take action.

Here’s how to calculate your conversion rate:

Conversions / Total Clicks x 100 = Conversion Rate Percentage

Click-through rate (CTR)

CTR shows the number of people who viewed your social media post and clicked on its CTA. It provides insight into whether your content captures your audience’s attention and inspires them to act.

Here’s how to calculate your CTR:

Total Clicks / Total Impressions x 100 = CTA Percentage

Sales revenue

To measure your sales revenue, you’ll need to use a web analytics tool Google Analytics. You can see which clicks from social media to your website converted into purchases and the total revenue generated.

If you’re using social commerce, you can track sales revenue in your shop analytics.

Social media KPIs for customer satisfaction

Customer satisfaction KPIs reveal how social media users think and feel about your brand. Social media interactions with your brand provide direct feedback for your business.

Customer testimonials

Reviews posted by your customers to social media channels like Google My Business or Facebook demonstrate how they feel about your brand. Star ratings also provide a quick snapshot of how customers perceive your business.

Response rate

If you provide customer support via social media, you’ll want to measure your response time. Customers expect quick responses, so the faster you acknowledge their comments toward you, the better.

Resolution rate

Not only do you need to measure response rate but also how quickly you resolve those issues and inform your customers. The impact on your brand is huge.

Customer satisfaction score

This metric shows how happy your customers are with your brand’s products or services. You could collect this data through a poll or survey. For example: “How would you describe your overall satisfaction with this product/service/brand?”

Respondents would rate their satisfaction on a scale from 1 to 10.

Customer loyalty

You could also measure your customers’ brand loyalty. Using a social media poll or survey, ask one question: “How likely are you to recommend this product/service/brand to your friends, family, or colleagues?”

Using the Net promoter score (NPS) customers can respond by selecting a number from zero (not likely) to ten (highly likely). This then categorizes customers into one of the following:

  1. Detractors: Customers who select 0-6
  2. Passive: Customers who select 7-8
  3. Promoters: Customers who select 9-10

Based on the number of people in each category, brands receive a score from zero to 100. The closer to 100, the better the score.

How to Track Social Media KPIs

In this section, we’ll cover how to set up and track your social media KPIs and highlight a few social media analytics tools that you could use.

How to set your social media KPIs

Before you can track your social media KPIs, you need to set them. Follow this 5-step plan:

1. Align your KPIs with your business goals

It’s important to ensure you align your social media KPIs with your business goals.

For example, if your business goal is to grow the brand, you’d want to build brand awareness on social media and then set Reach KPIs for the different platforms:

  • Business: grow the brand
    • Social media: build brand awareness
      • Social media platform: increase reach

2. Set your KPIs

After you’ve aligned your KPIs to your business goals, you can make your KPIs SMART. For example, if you want to build brand awareness on social media, you might use these platform-specific KPIs:

  • Increase Instagram followers by 10% in June.
  • Increase Twitter impressions by 30% in July.
  • Increase Facebook post reach by 5% in Q3.

3. Benchmark your current performance

Make sure you benchmark your current performance metrics so that you can measure the KPIs. For example, if you had 10,000 Tweet impressions in June and you want to increase by 30% in July, then you know your target is 13,000 Tweet impressions.

4. Define your cadence

Decide how often you’re going to track your KPIs so you can see trends – e.g. weekly/monthly/ bimonthly. If you don’t track frequently, you can’t react quickly when things aren’t working.

5. Review your KPIs

You need to review your KPIs regularly to ensure they’re still relevant and helping your business achieve its goals. Some campaigns are short, while others last longer, so you’ll need different review periods. Depending on your performance, you might need to adjust KPIs up or down.

How to track your social media KPIs

Now that you know how to set your social media KPIs, you need to track them. There are a couple of options.

1. Platform Analytics

Each social media platform has its built-in analytics, which is free and easy to use:

These tools are fine when you’re starting or only have a few accounts to monitor. However, if you’re an agency tracking several accounts across several platforms, it can become tricky.

At that stage, you’re probably better off using a social media analytics tool that pulls multiple platform metrics into one dashboard.

2. Loomly Analytics

Loomly’s Advanced Analytics includes account, post, and link metrics.

  • Account-level metrics, such as Page Likes on Facebook:
