Influencer Marketing: What Is It & Where Is It Going?

In my content marketing role at GRIN, I and my team have a front-row seat to industry developments – and they’re happening fast.

Speculating on the future of influencer marketing is no longer a discussion for marketing elites. DTC brands, in particular, are gathering tools and techniques to simply keep up with social commerce trends, not the least of which is the marketing power of this growing content creator world.

Is It Influencer Marketing or Customer Advocacy or Affiliate Marketing?

Even though influencer marketing as we know it is a recent phenomenon, the concept of celebrity endorsements is not new. But with today’s analytics, marketers can see the enormous benefits of niche gurus, influential customer shoutouts, social media creators, and more.

As often happens in the marketing trenches of an evolving medium, terms are starting to merge and differentiate. What do brands mean when they use labels like “ambassador,” “affiliate,” or “influencer”?

We can insist upon dictionary definitions, but those will fail us in the wake of change. Nevertheless, there are some high-level characteristics that allow me and my peers to distinguish among these terms.

Influencer Marketing

The term that seems most broad is that of “influencer.”

Influencers take many forms, from celebrities who endorse select organizations to mommy bloggers who share coupon codes. If there is one term that seems safest when describing social media power users that maintain thriving online communities, it’s the term “influencer.”

But if you’re a marketing manager working with content creators, “influencer marketing” may not be specific enough to your program’s mission, values, and goals.

Customer Advocacy

Customer advocacy programs often include influencers, but they certainly don’t have to. When brands recruit influencers into their advocacy communities, they’re more likely to refer to them as “ambassadors.”

As a whole, customer advocates are loyal customers that want to spread the word about the products that they love. Many of these customers are also influential on social media, and as a result, their word-of-mouth efforts easily fall within the umbrella of influencer marketing.

Affiliate Marketing

For many decades now, it’s made sense for some brands to outsource a portion of their sales to affiliates. Traditionally, affiliates are industry experts with a thriving publication channel and hefty conversion skills.

Though often falling on the “salesy” side of the influencer spectrum, affiliates typically demonstrate admirable content creation standards. They can attract prospects and guide them towards their purchase.

Many influencers and brand ambassadors assume an affiliate role with their favorite brands. This development is great news for everyone involved because creators get to monetize their audience, and brands enjoy more authentic brand mentions from affiliates.

As such, the occasional overlap between affiliate and influencer marketing has effectively raised the bar for sales authenticity on social media. Consumers don’t seem to mind the overt calls-to-action, so long as the influencer’s brand affinity is genuine, and consumers can see a healthy mix of branded and non-branded content on that influencer’s profile.

Top Industries for Influencer Marketing

Initially, influencer marketing was primarily a go-to strategy for young DTC, eCommerce brands. But now, major manufacturers and distributors are finding ways to leverage influencers and support retail partnerships.

But as eCommerce grows, so do all the ways that brands choose to leverage social media creators for awareness and sales. Among the leading industries for influencer marketing currently are:

  • Fashion
  • Health, wellness, nutrition, fitness, etc.
  • DIY
  • Travel
  • Gaming (eSports)
  • Entertainment and media streaming

Emerging Landscapes for Influencer Marketing

As SaaS solutions demonstrate better influencer attribution (that is, tracking which influencers are responsible for brand revenue, lead generation, and web traffic), more industries are jumping on board, including:

  • B2B brands
  • Mobile apps
  • Nonprofit organizations
  • Public works projects and government agencies

What are Influencers Worth? Comparing Costs and Value

Influencer worth is a hot topic these days, not because it’s debatable whether influencer marketing works, but because marketers keep discovering new ways in which influencers generate returns.

Simultaneously, social creators are coming to terms with their worth. Equitable pay for influencers is a growing movement as brands move away from traditional (and costly) ad and content design.

The most popular influencer performance metrics are:

  • Influencer media value
  • Reach
  • Content
  • Engagement
  • Conversions

Influencer Media Value

Influencer media value, or IMV, is the influencer expression of earned media value (EMV).

“IMV should demonstrate a comparable ROI to paid media. For example, an IMV of $100 indicates that your influencer marketing results generated what you could expect to achieve by spending $100 on digital ads. If you spent less than $100 on that particular influencer campaign, then you’ve achieved a positive ROI and better results than if you had spent those dollars on ads.” – GRIN, Quick Guide to Earned Media Value & Influencer Media Value

There are various formulas for calculating IMV. But the end goal is for marketers to understand what a particular influencer’s post is worth, based on that influencer’s engagement and relationship with their audience.

Influencers with a higher IMV generally produce more valuable engagement per post on behalf of their brand partnerships. This value also helps brands budget for their influencer campaigns.

Influencer Reach and Brand Awareness

Brand awareness is often the most-cited reason for collaborating with influencers. As a result, influencer reach becomes a critical metric.

A creator’s reach usually matches their follower count. That’s why marketers categorize influencers by how many followers they have, as such:

  • Nano – 1,000-10,000 followers
  • Micro – 10,000-100,000 followers
  • Macro – 100,000-1 million followers
  • Mega/Celebrity – 1 million followers or more

When calculating influencer reach, brands are increasingly aware of the imposters, known affectionately as fake influencers – users who buy followers and engagements to appear more valuable to brands. But thanks to updates on social media platforms and influencer credibility tools, it’s becoming much easier to weed out these fake influencers.

Still, costs generally increase with an influencer’s reach
. And it’s up to the brand to verify whether that creator’s audience is truly engaged.

Influencer Content Creation

Brands are beginning to see the merits of outsourcing social media content creation to their influencers. It saves production costs, is more authentic, and helps the brand build a library of repurpose-able content for ads.

“A creator is a production company in a box… Because they are partnering with a creator, a brand doesn’t have to go out there and hire a production company or hire an agency or hire actors to star in content. There is a lot of value that the creator brings.” – Justin Moore, Founder & CEO of Creator Wizard

Content volume metrics ensure that brands achieve a sufficient amount of IRL (in real life) content to showcase their products, as well as provide informal FAQs and case uses. Consumers favor this content because it comes from a lifestyle expert that they trust and want to emulate.

When factoring in the cost for these content creators, brands often test the quality of an influencer’s creative skills in a one-off or product gifting campaign. After a couple of mutually beneficial partnerships, the brand and creator negotiate rates for an extended contract.

Influencer Engagement

Engagement is the single most often tracked campaign metric in all of influencer marketing. Meaningful interactions between influencers and their followers facilitate ongoing user-generated content from followers and fans. And with each new engagement, brand mentions can increase the number of impressions per post.

what influencers are worth

This online chatter often translates into increased brand awareness, sales, website traffic, and new followers on that social media channel.

As influencer attribution and social listening technology advances, marketers are even able to distinguish between the value of vanity metrics (followers and likes) and non-vanity metrics (comments, shares, duets, etc.).


For smaller influencer and ambassador programs still using manual tracking tools, conversions through affiliate links and discount codes are the easiest metrics to follow. Conversion-based partnerships often result in commission influencer payments to incentivize…
