How to Track Influencer Marketing Success: 6 Effective Ways

Updated: Jul 20, 2020

Influencer marketing may have quickly become one of the most popular methods of digital marketing. However, it’s far from perfect, and one of the major reasons for that is the fact that marketers still don’t know how to track influencer marketing effectively. In fact, measuring influencer marketing ROI is a major challenge for 52% of marketers.

Why do you need to track influencer marketing?

By tracking influencer marketing success, you’ll be able to figure out what works for you and what doesn’t. This can help you make more informed decisions in the future to boost your influencer marketing campaigns. It’s perhaps due to this reason that nearly 39% of brands in the USA would be more likely to invest in influencer marketing if they could measure its overall impact on business growth.

So, before we get into how to track influencer marketing, let’s take a look at some of the metrics you need to measure to determine the success of your influencer campaigns.

Pro Tip: Decide on the goals of your influencer marketing campaigns and measure your success based on them.

Which Metrics Should You Track for Influencer Marketing Success?

Here are some of the metrics that you should use for influencer tracking:

1. Input

Input includes the activities that you undertake in the identification phase of your influencer marketing campaigns. These include activities such as:

  • Social media influencer outreach

  • Inviting influencers to your events

  • Sending out invites for your influencer program

  • Asking employees to become influencers

To get your input metrics right, you need to understand which social channels your target audience is active on. This is essential because it’s on the basis of this that you can find influencers who can reach them.

Partnering with influencers on social platforms other than those where your audience is active, may not be beneficial. This is because you won’t be able to reach your target audience through the influencer campaign.

2. Output

Output includes the activities that have actually converted into engaged and activated influencers.

Some of the things you need to measure when it comes to your output are:

  • How many influencers accepted your invitations to the events?

  • How many influencers turned up for your event?

  • How many influencers joined your influencer program?

  • How many influencers engaged with your brand once you messaged them?

  • How many relationships did you manage to build?

Measuring these things will help you figure out how effective your efforts were during the initial stages of your influencer marketing campaigns.

3. Outcomes

The outcomes of influencer marketing campaigns deal with the final results of the campaign. These include metrics like engagement, brand awareness, sales, lead generation, etc. Outcomes of your influencer campaign are usually related to the campaign goal. For instance, if your campaign goal is to generate sales, the result of the influencer campaign should be more conversions and sales.


Engagement is one of the most important metrics that you need to measure when you want to find the effectiveness of your influencer marketing campaigns. It’s essentially a measure of how well your target audience has received your influencer’s content.

Some of the engagement key performance indicators (KPIs) that you should track for influencer marketing success are:

  • Engagement Rate: Engagement rate is one of the most important metrics to track your influencer marketing efforts. It gives you an idea of the percentage of the influencer’s audience who interacted with your sponsored post. You can find the engagement rate by using the following formula:

When your goal is to build awareness for your brand, you need to track key performance indicators (KPIs) related to awareness for influencer marketing. Some of the important ones you need to measure are:

  • Reach: The reach of your influencer campaign shows you how many people may have potentially seen the post created by the influencer. Nearly 59% of brands tracked the reach of their influencer campaigns in 2019 to figure out if they were successful. The potential reach of every campaign is equivalent to the number of followers the influencers have.

  • Impressions: It’s difficult to estimate the exact reach of a campaign, so it’s better to track the impressions if you’re looking for a more precise answer. This gives you an idea of the number of times people saw your post.

  • Audience Growth: Yet another important awareness metric to track influencer marketing is that of audience growth. It essentially shows you how many new followers you’ve got through the influencer marketing campaign.


Influencer campaigns can also help drive traffic to your website. This traffic boost can help you ramp up your lead generation and sales. While it’s essential to track the number of clicks on the website link and calculate the click-through rate, it’s also necessary to check the growth in website traffic.

But, why?

This is because the link clicks may not always convert into website traffic. Some of the people who’ve clicked the links may bounce away before your site opens. This is perhaps the reason why nearly 40% of brands track website traffic to determine influencer marketing success.

They might even use your branded hashtags in their content marketing efforts.

The earned media value generated by this content can help you increase your brand awareness and authority.

When a social media influencer incorporates your website link into their posts, many of their followers may click on it and go to your website. This can help increase your page views. Additionally, the highly-targeted traffic means that your time on site and bounce rate metrics will be impacted positively.

So, what does this do?

This can help improve your SEO. Not just that, when social media influencers add links to your website in their blog posts, it can get you some valuable backlinks and traffic. This can improve your SEO as well.

5. Open Google Analytics and head to Acquisition -> Campaigns -> All Campaigns and select your goal. This will bring up the exact figures based on the chosen goal.

2. Social Data

Each social media platform has its own built-in analytics tools that you can use for this. All you need to do is open your social media accounts and head to the analytics section.

Not sure where to start?

You can check the influencer’s sponsored posts and find out the number of likes, comments, and shares. For tracking content generation, you can check how many posts have been created using your branded hashtag and find out your earned media value.

Additionally, you can find out your follower growth using social media analytics tools. However, for the other metrics, you need to have access to the influencer’s social media account.

So, what can you do?

A great way of going about this is by asking the influencer to send their analytics to you. This can help you find out your reach, the number of impressions, clicks, CTR, and even CPC.

3. Promo Codes to Measure Sales

Yet another method of tracking your sales is by providing unique promo codes to your influencers. When any of their social media followers use these promo codes when they’re purchasing your products, you’ll be able to track the sales.

But how can you do so?

To track the sales, you can utilize POS systems that support promo codes. Alternatively, you can use tools such as Voucherify and to track the sales generated through promo codes.

4. Subscriber Database Growth

Tracking the number of email newsletter subscriptions is fairly easy if your email marketing platform has a built-in analytics tool. You can use these analytics to determine the number of new newsletter subscriptions.

5. Measuring Input

Input is the activities that you do at the beginning of your influencer campaign. Hence, measuring your input requires that you track the activity and effort that your team is putting into the campaign.

So, how can you measure your input?

You can do so by finding out the following:

  • The number of outreach emails or messages sent to the influencers

  • Number of influencers invited to join your program

  • Number of influencers invited to attend your event

  • The number of employees you’ve reached out to get on board for an employee advocacy program

These factors are some of the most basic ones and are the first steps you need to take to measure the success of your influencer marketing campaign. If your campaign doesn’t do well, you might need to improve your marketing strategy and input activity.

6. Measuring Output

The output of your influencer marketing campaign is essentially the results of your input activity. Hence, measuring them requires that you track how your input has led to you getting engaged and active influencers on board.

Here are some of the questions that you need to answer to measure the output of your influencer campaign.

  • How many influencers responded to your outreach messages or emails?

  • How many influencers accepted your invitation to the event?

  • How many influencers actually turned up for your event?

  • How many influencers joined your influencer marketing program?

  • How many employees have started posting about your brand?

Answering these questions can help you track your output.

7. Check Your Site Analytics

While it can be difficult to find out the exact impact of the influencer campaign on your SEO, you can get a rough idea by going through your website analytics. For this, you can head to Google Analytics.

What should you look out for?

Check your referral traffic to figure out how much traffic the influencer is driving from their post or website. Additionally, you can look into other metrics of this traffic to figure out its effectiveness. These include:

  • Time on site

  • Bounce rate

  • Pages per session

  • Pageviews

Next, you can figure out the quality of traffic that the influencer is driving to your website. You can also check the impact that the traffic has on the average of these metrics, and you can compare them to those before the campaign. This can give you an idea of how the campaign has affected your website’s SEO positively.
