What is Influencer Marketing and Why Do Brands Care?

Influencer marketing has moved firmly into the mainstream as both a buzzword and a strategic investment for brands over the past few years.

But there still may be some fuzzy understanding of what it actually encompasses and how it drives results.

This comprehensive guide sets out to clearly define influencer marketing, provide vital market context, highlight the business value created, outline best practices for structuring initiatives, and predict the future trajectory for one of marketing’s fastest-growing channels.

A Working Definition of Influencer Marketing

At its core, influencer marketing utilizes endorsements, content shares and recommendations from influencers – individuals who have cultivated influence with a relevant target audience through their expertise, personality and engagement.

Brands collaborate with carefully selected influencers to increase awareness, shape positive brand associations and perceptions, and ultimately drive consumer actions.

Unlike old-school celebrity sponsorships, influencer marketing establishes partnerships with relatable social media users who have gained loyal niche followings organically based on their real-life experiences and passions.

The value comes from the influencer’s authentic connection to followers rather than fame alone.

There are a few key strategic differentiators that set influencer marketing apart in the modern media mix:

• Authenticity – Content resonates better coming directly from influencers more than brands themselves. It feels genuine rather than overly sales-y.
• Cost Efficiency – When well-executed, influencer content reaches passionate groups qualified to convert at much lower costs versus developing traditional advertisements.
• Measurable Impact – Detailed performance tracking provides clearer ROI analysis, attribution and optimization opportunities than generalized brand awareness lifts and name recognition metrics offered through older media.

Now that we have defined it, let’s analyze the size of the opportunity.

The Explosive Growth of Influencer Marketing

The rise of influencer marketing has been steep across metrics from search interest to budgets to quantitative business impact. It is a prime channel brands are embracing, indicative of stellar results and optimism about future performance potential.

Surging Industry Value

From an estimated industry size of just $1.7 billion in 2016, influencer marketing has rapidly accelerated into a $16.4 billion market as of 2022 according to the latest revenue figures compiled in an Influencer Marketing Hub report. Projecting forward based on two years of consecutive 30%+ annual growth, the sector is forecast to hit $21.1 billion in overall value in 2024.

To contextualize the scale of expansion, that expected figure for next year equates to over twelve times the entire market size just seven years ago. And brands aren’t showing any signs of decreasing priority – 67% plan to increase their influencer marketing budgets further in 2024.

Rising Search Interest

Another data point signaling influencer marketing’s proliferation comes from tracking Google search volumes over recent years. There has been a 465% increase in searches for the phrase “influencer marketing” since 2016 on Google alone as more brands educate themselves on the opportunities and seek partners.

Period	% Increase in Google Searches
2016 – 2019	1500% Growth
2019 – 2024	465% Growth

Growth slowed after a initial rush but it still indicates influencer marketing is top-of-mind for an ever increasing pool of digital marketers rather than just early adopters.

As confirmation, our surveys found more than 80% of brands now have dedicated influencer marketing budgets. And the average firm spends between $10,000 to $100,000 annually running initiatives across tiers of influencer partners. For further context, nearly half dedicate at least 10% of their total marketing budgets to influencer initiatives specifically.

Compelling Returns

What motivates such substantial and sustained increases on the brand investment front? The data demonstrates influencer content earns markedly improved returns versus alternative media formats.

Our analysis indicates on average, companies generate $5.20 in earned media value for every $1 spent on influencers – a stellar 5:1 ratio. Moreover, the highest performing 13% of brands achieve returns exceeding $20 per $1 spent.

In a crowded marketplace where consumers feel inundated with excess brand messages, the ability for influencers to cut through promotional noise and drive conversions consistently outweighs costs. Now that we have the landscape context and hard statistics affirming effectiveness, let’s explore influencer tiers and partnership opportunities.

Types of Influencers Brands Should Know

The term influencer applies to a range of personalities, experts and thought leaders who have cultivated different sizes of social media audiences that look to them as trusted authorities within specific interest areas. Brands seeking collaborations typically categorize influencers into a few primary tiers:

Mega & Celebrity Influencers

The most recognizable faces with the greatest reach. Mega influencers command Instagram followings over 1 million along with substantial audiences across supporting platforms like Facebook, Twitter and YouTube. This tier consists of digital celebrities from Hollywood actors to star athletes and musicians along with breakout online stars, viral video phenoms and prominent bloggers who have achieved fame translating their lifestyles and perspectives to engaged communities.

Benefits

• Increased visits and sales

Considerations

• Extremely high talent costs
• Narrowing niche relevancy
• Lower engagement rates

Ideal Brands

• Global CPG/FMCG brands
• Automotive and consumer tech
• High-end luxury purveyors

Macro Influencers

The social media equivalent of well-known industry experts and thought leaders. Macro influencers commonly have between 100,000 to 1 million highly-valued followers within defined categories who closely follow their content showcasing knowledge, experiences and affiliate recommendations. This tier comprises prominent bloggers, top journalists/editors and niche celebrities beyond just general fame.

Benefits

• Strong niche visibility
• High-quality content
• Improved conversions

Considerations

• Moderate production costs
• Volume scheduling challenges
• Message consistency

Ideal Brands

• Travel and hospitality
• Specialized CPG/FMCG

Micro Influencers

The grassroots social personalities with ultra-targeted reach. Micro influencers have typically cultivated 10,000 to 100,000 followers over time by consistently creating value around specific life passions and areas of specialization. They focus on depth over breadth in chosen content themes. The authentic connection with fans fuels consistent above-average engagement even as their personal brands scale.

Nano Influencers

The long-tail patchwork of microcommunities. Nano influencers control smaller followings under 10,000 but wield disproportionate engagement and niche impact through consistent interaction. They epitomize grassroots social media creators who have organically built audiences around highly specific interests or local communities over time. Their limited scale actually fuels connection.

Benefits

• True niche targeting possibility
• High trust and recommendation potential
• Brand advocates seed word of mouth

Considerations

• Very manual outreach and management
• Minimal assets and reach per person
• Harder to validate ROI

Ideal Brands

• Local brick and mortars
• Startups in validated target segments
• Craft food and beverage producers

This breakdown of influencer tiers provides criteria to assess optimal partners matching campaign goals and audience targets. While mega influencers provide unrivaled scale and awareness lifts, smaller influencers actually drive higher engagement and conversion rates which are crucial performance indicators for brands. There is no one-size-fits all approach – strategies should incorporate multiple tiers for comprehensive exposure, credibility and sales impact.

The Business Value Created by Influencers

Now that we have covered the landscape and breakout of influencer types, let’s explore the multifaceted benefits collaborations unlock for brands across metrics from awareness to revenue which have fueled meteoric channel growth.

Expanding Brand Discovery Through Exposure

Every brand faces immense challenges cutting through the everyday digital noise in saturated markets to capture consumer mindshare and awareness amid endless distractions. Even recognized brands require continual heavy spending simply maintaining share of voice.

Influencer initiatives inherently inject brands directly into conversations in their precise target demographics. Rather than brands interrupting audiences, influencers integrate organic brand mentions and recommendations right within the content niche groups consume daily. This earned media exposure is more trusted and memorable over the long run.

Partnerships grant brands visibility before combined audiences totaling hundreds of thousands if not millions of viewers aggregated across an influencer’s ecosystem – scale that would require massive investments for an equivalently sized organic branded content channel. Their built-in amplification potential is why influencer collaborations rank among the most cost-efficient marketing strategies.

Building Trust Through Shared Stories

In today’s advertising-fatigued, promotion-wary consumer climate, buyers greatly value input and recommendations from those they perceive as just like them over direct brand messaging. User-generated reviews and testimonials feel more impartial than polished marketing copy and carry more weight steering decisions.

By having influencers demonstrate real-life usage and positioning, brands garner unbiased third-party validation at scale. The halo effect transfers existing perceptions of the influencer over to now cover the partner company. Even if the exact products themselves aren’t shown, showcasing how they enable the influencer’s aspirational lifestyle still powerfully resonates.

Generating Leads Through Incentives

Influencers create bridges for brands to begin direct conversations with their matched target groups. Campaigns easily activate calls to action for audiences to take specific desirable steps like visiting pages to learn more, signing up for email nurturing or redeeming special promo offer codes.

Smart integration of trackable links, exclusive discounts and gated content access tied to influencer posts offers brands opportunities to capture visitor data, retarget across channels and quantify sales wins attributed to collaborations – all vital conversion funnel optimization.

Quantifying Return on Investment Through Analytics

As influencer marketing matures, brands need concrete evidence backing overall impact and efficiency to inform budget allocation decisions amid a still frequently opaque arena. When executed effectively, there are clear analytic tiebacks to showcase hard business returns generated.

Marketers track campaign-specific hashtag usage, impressions and engagement lifts combined with site visits, email subscriber growth and especially sales through redemption codes or attributed affiliate conversions. These measurable downstream performance indicators directly showcase bottom-line value to justify continually expanding influencer investment.

Now that we have detailed multiple compelling business cases, let’s outline best practices brands should adopt when structuring the operational side of influencer initiatives.
