Influencer marketing is one of the fastest-growing advertising channels. One of the most daunting issues businesses face when adopting an influencer marketing strategy is how to measure their return on investment (ROI). There are valid concerns, but also a host of misconceptions, around determining influencer marketing ROI. This prevents from brands from adopting influencer marketing altogether.
- Social reach of the influencer (i.e. how many followers across given social media channels)
- Type of sponsored content (e.g. Instagram in-feed post, Instagram Stories post, YouTube video, Twitter Tweet, Twitch activation, blog post, Facebook post)
- Length of sponsored integration (for example, a one-off Instagram Stories post will cost less than a series of Instagram videos spanning several months)
How can marketers measure their return on investment for influencer marketing campaigns? Marketers must think critically about all the costs associated with an influencer marketing campaign before setting a budget. There can be hidden costs that impact ROI in running an influencer campaign in addition to the sponsorships fees.
This article aims point out potential hidden costs that impact ROI but aren’t initially obvious. Ultimately, marketers must decide how they will measure campaign success in order to judge effectiveness.
Influencer Marketing Return On Investment (ROI): A Marketer’s Guide
The Formula For Influencer Marketing ROI
Return on investment is generally reflected as a percentage (i.e. the percentage of each dollar invested that will yield a profit).
The simple formula for calculating influencer marketing ROI is:
That means this campaign generated a positive ROI and can be considered a resounding success. This hypothetical example is simple, but calculating influencer marketing ROI gets more complicated in practice.

One of the most crucial steps to launching an influencer marketing campaign is deciding on your goals. Your goals will inform how you measure results. Campaign results are a critical component of measuring the “return” of ROI.
The KPIs for your influencer marketing campaign are determined by your overall goal. Influencer marketing campaign goals generally fall into two broad categories: brand awareness or direct response.
Metrics for Measuring Brand Awareness
- Social Reach: Followers, Subscribers, Impressions
- Engagement: Likes, Comments, Sentiment, Shares, Mentions
- Press, Media Mentions, Website Traffic
Followers & Subscribers
Social media following is the tally of followers an influencer has across all their social media channels. If an influencer shares sponsored posts on their Instagram and YouTube channels, then add up their Instagram followers and YouTube subscribers to calculate total following.
Social media impressions are defined as the number of users that have viewed a social post. Impressions are a critical metric for determining a campaign's reach and a preferred way to measure social reach compared to “following.” You'll be able to view impressions using the native analytics platforms for each social media channel (i.e. review Instagram Insights).
Engagement rate measures the audience’s interactivity in relation to a social media post. Engagement speaks to how well an audience receives a post. The key performance indicators (KPIs) that are tracked for social media engagement are:
A “like” is the virtual thumbs up that’s ubiquitous across social media platforms. A well-liked photo or video not only signifies esteem with users, but also factors positively into some social platform’s algorithms, increasing the post’s visibility. For example, the more likes an Instagram photo receives, the more prominently it will be featured on users’ Instagram feeds.
Slightly different terminology is used for “Likes” on certain channels, for example Instagram likes are reflected as a double-tap heart and YouTube likes are tallied as a “thumbs up.”
On YouTube & Facebook, users have the option of disliking posts. YouTube viewers can “thumbs down” videos and Facebook users can react with anger or sadness to posts. The ratio between Likes and Dislikes will indicate which posts resonate with users.
Comments & Social Sentiment

Comments are written responses to a social media post. Users who leave a comment are showing exceptional interest in a post. Comments speak to the post's popularity, particularly when commenters start a dialogue about its content.
Comments are a useful qualitative metric and an excellent way to understand user response to social media content. Gauge social media sentiment by reading the actual content of comments. Signs of positive social sentiment are:
- Enthusiasm for your product, especially indications of purchase intent (e.g. “NEED those metallic sandals!”)
- Positive emojis
- Tagging friends
- Branded hashtag use
- Mentioning your brand, especially engaging in conversation, replying to questions, or making inquiries
- Compliments about the content itself (e.g. “Really creative photography!”)
When a user shares a social media post, they are explicitly endorsing that content. Shares help to expose the content to new audiences outside the reach of the original post. Each social media platform has its own set of Share options:
- Instagram: Sharing to your feed in a conventional sense requires a “repost” app or screenshot (the best way to track is by reviewing your brand mentions on Instagram).
- Facebook: Sharing displays the post on your own Facebook timeline
- Twitter: Retweeting posts the tweet on your Twitter feed
- Pinterest: Repinning a Pin adds it to a Pinterest board that you choose
Shares aren’t recommended KPIs for YouTube and Twitch, because the Share options are off the platform and difficult to track.
Your brand may base an influencer marketing campaign around growing your own social media following. Track the average follower growth in the months leading up to an influencer activation as a benchmark, so that you can distinguish organic follower growth from followers who discovered your brand via an influencer.
Mentions & Hashtags

🍁🍁🍁 This place has always been a special spot for memories. I used to drive out here as a kid with my parents during the fall and collect as many different coloured leaves as I could (probably a part of when my minor 🍊 obsession started 😂). Once I got my license, I always made @Shell a part of my journey here through all these years, and I swear this drive only gets more beautiful with time. PS. I sadly couldn’t find an 🍊🍁 cause they were all gone! Proof that there’s only a small window of time when the leaves change - make sure you take the time to explore all the beautiful things we’ve been blessed to have 🙌🏻 #ShellPartner #ad
Social media mentions happen when a user mentions your brand by name using an @ tag (e.g. @Mediakix). Users will also integrate brand hashtags into their posts. Both hashtags and mentions show a high level of brand affinity and social alignment. Generally, mentions expand your brand’s exposure while hashtags help disseminate buzz about a specific marketing campaign.
Dark Social AKA DMs
"Dark social" refers to social media actions taken that are private, meaning the interaction is only visible to the account holder and user. For example, direct messaging is private, thus only the sender and recipient can view the contents of a message. Dark social metrics will show you when a user:
- Saves or favorites a social post
- Uses direct messaging to share social content
- Emails the link to the social post
Press & Media
Press coverage around your influencer marketing campaign helps to spread your message even further. Media mentions and links to your website boost brand awareness. You’ll find that increased media coverage produces a “halo effect” around your website, increasing the overall traffic from all sources: organic, referral, social, and direct.
Direct Response Goals & KPIs
If the goal is direct response, KPIs might include sales, downloads, or signups, depending on the product or service.

And to think I almost didn’t go hiking this day :) So my very first backpacking trip was 12 years ago in this valley below me. It’s funny to think how new it all was then - to give you an idea I had a sleeping bag tied to my school backpack with fishing line. From then on I was hooked and I used to squeeze in overnight trips between getting off work in the afternoon and racing down the mountain at sunrise to get back on time. I’ve learned a bit since then (and my gear has gotten a lot better) but the bliss is still the same. Get out there. Squeeze it in where you can. I never know when that exceptional outdoor moment will be, and I never regret that extra bit of sweat I put in when I’m there to witness it. - For anyone looking to update or get into some better outdoor gear I’m partnering with @backcountry to share my #GOATworthy moments and you can use my code “CHELSEA15” for 15% off your first purchase at Backcountry.com. They have everything from lightweight technical apparel to super cute and cozy brands from some of my favorite brands like Patagonia and Freepeople.

Product purchases are a gold standard of measuring return. Product sales can be analyzed with greater nuance by honing in on specific metrics like revenue, average order value, or cost-per-acquisition.
A signup occurs when a customer submits their information to:
- Subscribe to a newsletter or product (e.g. start a beauty box subscription)
- Create an account (e.g. join the Starbucks Reward Program)
- Become a member (e.g. enlist in the ACLU)
Click-Through Rate (CTR)
“Click-through” or click-through rate (CTR) describes the number of times consumers click on a suggested link in a promotional post. These clicks will lead the user to a dedicated URL (like a landing page or product page) where they are prompted to convert.
Downloads are digital products, like apps, software, ebooks, or whitepapers. Download transactions are common KPIs for mobile games and B2B companies.
The Costs Of Influencer Marketing

In order to calculate ROI, you’ll need to tally the costs that go into an influencer marketing campaign. Possible costs include:
Time & Staffing
Properly researching and vetting potential influencer partners requires many hours scouring social media channels and the internet. Next, you’ll need to track down influencer contact information, write a campaign brief, and reach out to the influencers.
As many influencers are inundated with brand requests, your message must be carefully polished to cut through the noise. After, there’s negotiation and coordination with influencers which requires time to manage the relationships.
These steps are time-consuming and require personnel to manage. Depending on the size of your influencer marketing program, this might mean investing in training programs or creating a dedicated role for influencer management.
Software Costs: Influencer Marketing Platforms
Brands can manage their campaigns through specialized influencer marketing software. An influencer platform is a software-based directory where companies can search for influencers across social media platforms. These searchable online directories with a wealth of data about influencers (e.g. gender, audience demographics, engagement rate).
It’s a two-way street—influencers themselves can also join a platform to seek out brand sponsorship opportunities.
Platforms are subject to recurring monthly fees to access the platform. Mbany platforms will charge a flat fee or percentage fee of total campaign budget for activations that result from platform use.
Pro Tip: Most influencer marketing software has analytics capabilities which streamline reporting and analyzing results.
Marketing Agency Fees
The major financial benefits of working with an influencer marketing agency are:
1. Time Saved: Outsourcing the major time investment needed to manage an influencer marketing program.
Partnering with an influencer marketing agency greatly reduces your brand’s need for manpower to run a successful influencer program. Agencies can own the work that your brand’s internal staff would otherwise manage.
2. Lower Influencer Rates: Securing lower influencer fees by leveraging established relationships.
Influencer marketing agencies have cultivated relationships with influencers and possess records of their performance. Agencies also have the ability to negotiate influencer fees. This allows agencies to secure preferred influencer rates to help keep costs down. Agencies can offer an economy of scale by bundling costs across multiple campaigns.
3. Data-Driven Campaigns: Applying data from past campaign performance to inform influencer selection.
Agencies can leverage experience and data to guide brands towards choosing the influencers who will likely provide the best ROI. Their industry expertise can help your company avoid wasting money on influencer activations that won’t achieve your desired goals. Agencies only work with influencers who use reputable business practices (i.e. no fake followers or fishy engagement stats), so the metrics achieved are reliable.
- Popularity: The number of followers across all social media channels.
- Engagement: How much their audiences respond to their content through shares, comments, and likes. Many influencers take this engagement to the next level, by launching their own products or hosting events, which can impact their ability to command a larger fee from brands.
- Production Quality: Creators put effort into creative planning, production, and marketing for a full campaign. Social media influencers who are especially skilled at photography, videography, editing, visual design, or writing can charge more for brand sponsorships.
- Niche Skills: Specialized skills like baking, crafting, construction, interior decorating, sewing, singing, painting, and humor can all translate into higher fees for sponsored content.
- Past Performance: It’s now an industry standard for influencers to have an impressive portfolio of brand collaborations, a media kit, and proven results working with brands. Creators who can vouch for their ability to drive results for brands can justify a hefty fee.
- “It” Factor: Like anything, some influencers just have that indefinable “je ne sais quoi” which makes them a desirable ambassador to many brands. Whether this comes from buzzworthy content, cult of personality, sensational stunts, influencers who achieve that “it” status will be able to charge more based on demand.
Pro Tip: If you’re working with bloggers, metrics like site traffic and email subscriber list also factor into their popularity and creator fee.

GIVEAWAY TIME! 🎁 I love traveling, but my skin doesn't. To help with dryness and fatigue, I always travel with a face mask and one of my favorites in the last year has been the @freshbeauty Lotus Youth Preserve Rescue Mask. I put mine in the fridge when I arrive at my hotel so when I'm ready to use it, it feels like I'm getting a facial... but it only takes 5 minutes. 🙌 Any puffiness or redness from being on the plane disappears. Plus, my skin is suuuper glowy and I usually skip foundation/tinted moisturizer altogether. I'm so excited that this mask now comes in travel size along with three others in the Great Mask Escape set for the holidays. And guess what? One of YOU will win this set! Just give this photo a like and leave a comment telling me how you practice self-care when you travel. Good luck! #GiveFresh P.S. this set + more are available @nordstrom!
If your brand sells a product, you’ll need to provide creators with product samples. If your brand sells a service or experience, the influencer will need to try it out before creating branded content.
- Specialized props or sets
- Additional talent like models, hosts, or actors
- Makeup artists
Your brand can opt to boost a social post after an influencer has shared it on their feed, using paid advertising to acquire even more impressions.
Pro Tip: Repurpose the high-quality content created by influencers for your blog, social channels, and email marketing in order to make the most of your investment. Be sure that your influencer agreement grants you usage rights, so that you can legally share the campaign creative.
Developing influencer contracts around terms, ownership, licensing, and disclosure needs to be factored into any influencer marketing budget. Whether you have an in-house attorney or a contract lawyer, legal fees can be substantial. This belies the importance of using an airtight influencer contract and adhering to FTC guidelines around sponsored content to protect yourself from a costly legal hassle down the line.
Measurement & Tracking
Tracking results is a crucial component of measuring influencer marketing ROI. In terms of data measurement, costs to take into account include:
- Analytics software or platforms
- Developer resources to implement tracking
- Time spent crunching numbers
- Manual gathering of screenshots and qualitative results
ROI By Social Media Channel And Post Format
All social media channels are not created equal when it comes to measuring ROI. Some social media channels and content formats offer relatively stronger engagement levels, more extensive analytics, and greater capabilities for measuring and achieving ROI. For example, YouTube’s long-form video format attracts a highly engaged audience, and their robust tracking capabilities enable more demonstrable ROI.
When planning a campaign, marketers should consider the engagement levels on their targeted channel (e.g. Instagram) and desired post type (e.g. Instagram Story), and how easy it will be to track performance in this medium.
Channels with strong correlation to direct measurable ROI:
- Instagram Stories allow influencers to use two types of CTAs: a verbal call to action and the “Swipe Up” trackable link within the Story. Brands also have the option of having influencers use a promo code.
- YouTube videos provide many opportunities for user conversion. The key CTA in a YouTube video is verbal -- influencers will encourage their audience to take action during the video itself, when viewers are paying close attention. YouTubers can also add a trackable link in the video description box, or offer coupon codes. Audiences are generally highly engaged with video content, and YouTube offers comprehensive video impression metrics for tracking engagement on a sponsored video.
- Sponsored blog posts are very trackable due to the robustness of web analytics, which provide extremely detailed results on user behavior. Bloggers include trackable links and written CTAs within the body of their blog post, which can be tracked directly back to site traffic or conversions
Channels with weaker correlation to direct measurable ROI:
- Instagram in-feed posts are difficult to measure for direct response campaigns because linked CTAs are not allowed within Instagram post captions. Users also tend to scroll through their Instagram feed very quickly, whereas they are more likely to linger on video content.
- Twitch activations are difficult to track because streamers promote brands as part of a livestream broadcast and then cross-promote the content on multiple channels. While viewers are highly engaged during Twitch Streams, it’s difficult to track direct engagement with the brand.
Tools For Measuring & Tracking Influencer Marketing ROI
You’ll need to lock down appropriate measurement tools to track KPIs before launching influencer marketing campaigns.
Recommended tracking methods include:
Google Analytics (GA), the ubiquitous platform for tracking website performance, is a powerhouse of data. GA is completely free and extremely customizable; you’ll be able to track traffic, unique visitors, and more. Other data analytics platforms can be used instead of, or in tandem with, GA including Adobe Analytics, Tableau, and Salesforce.
Social Platform Native Analytics
Social platforms have native analytics to track platform-specific metrics like impressions, views, likes, hashtags, and comments. Specific data will vary by social media platform.
Third Party Analytics
Use a third party analytics tool that’s able to synthesize social media metrics to provide deeper insights. Some tools can pull in data from other data sources (like Google Analytics or your company’s CRM), which greatly boosts their power in providing detailed data. Using a social media suite can be especially helpful for complicated influencer marketing campaigns that involve multiple influencers and social channels. Popular social analytics tools include Hootsuite, Sprout Social, and HypeAuditor.
Measurement of brand sentiment and brand affinity will require qualitative research. Third party analytics tools can use algorithms to review the language used in comments and provide this qualitative data. For smaller campaigns, a manual approach might be the most practical.
Pro Tip: Using a social media analytics suite is highly recommended for complex influencer campaigns since you’ll be able to drill down data for individual activations or take a high-level look at the overall campaign success.
Trackable links are the ideal way to measure CTR. Common ways to track links include:
- Using link shorteners (e.g. Bitly or Google URL Shortener).
- Creating UTM codes to attach a unique source, medium, and campaign name to your URL
- Unique, custom URLs for each influencer (e.g. www.example.com/influencer-name-sweeptakes-2019)
- Using vanity URLs (e.g. www.example.com/win)
Companies using GA to track will most often use specific UTM codes for each influencer and social media channel. The UTM codes are generated by Google, allowing for tracking the tracking of metrics including clicks, sales, and conversions.
Dedicated Landing Pages
Develop a dedicated landing page with messaging tailored specifically to an influencer’s audience. Through that landing page entry point, you can track visits and conversions resulting from the influencer’s branded post.
A conversion pixel is a tiny 1x1px image which is placed on the destination page linked to a sponsored social media post. Whenever a user reaches the destination page, the image loads counting as a visit. Conversion pixels are used exclusively in conjunction to paid social media campaigns, like Facebook Ads.
Post Campaign: Analyze Your Results to Calculate Influencer Marketing Return On Investment (ROI)
1. Add Up Your Expenses
Start by adding up every expense that went into your influencer marketing campaign.
Account for Hard Costs
Account for hard costs, like the influencer fee, agency fee, and production costs first.
Decide How To Measure Tools Used For Multiple Campaigns
Next, you’ll want to add up costs for tools used for multiple activations, like influencer platforms or social media analytics software.
Recurring expenses, like subscription to a software, are slightly more complicated because they often span across multiple campaigns. The key is to replicate the same formula for each influencer campaign so you can compare results between campaigns.
Say, for example, you use an influencer marketing platform for five different influencer activations over the span of a month. You would count 1/5th of the monthly subscription fee as a cost for each individual influencer activation.
2. Add Up Your Return
Start by adding up direct response KPIs like purchases and subscribers. These types of returns are the most straightforward to quantify.
There are many ways to determine a value for direct response KPIs, for example:
- Site Visit: Calculate the average CPC for paid search traffic
- Social Media Follower: Divide revenue originating from social channels by your total number of social media followers over a specified time period
- Newsletter Subscriber: Divide revenue via the email channel by your number of active subscribers over a specified time period
There are no universal industry standards for measuring the return of an influencer marketing campaign. Most businesses rely on existing sales funnel data to establish their own benchmarks to assign value to each KPI.
Brand Awareness Benchmarks
Establish values for each KPI (i.e. a social impression is worth $0.08, a site visit is worth $1.06).
Brand awareness KPIs are not associated with a standard dollar amount because the value varies tremendously based on industry and business model.
3. Calculate Influencer Marketing ROI
Once you establish a standard method of exactly how you’re calculating costs, use the formula to calculate your influencer marketing ROI.
Tips For Achieving A Positive Influencer Marketing ROI
As with any type of paid media, it’s not possible to guarantee a positive outcome. Working with an experienced influencer marketing agency or hiring a seasoned influencer manager will help.
Some guidelines for achieving a positive ROI on your influencer marketing campaign:
- Focus on ONE call-to-action for your campaign—conflicting CTAs usually lead to confusion and no action.
- Provide limited talking points to influencers to hone your message.
- Do your homework vetting influencers so you don’t work with an influencer who has fake followers or an audience that isn’t suited to your brand.
- Allow the influencer creative freedom—this will elevate the content and make it more organic.
- Make your campaign interactive, which might mean hosting an event, sponsoring a giveaway, or offering an exclusive promo.
- Iterate! Test campaigns on various influencers, learn from successes and failures, and embrace trial-and-error as part of the process.
