Influencer Marketing in Numbers: Key Stats

Influencer marketing has grown into the most data-driven division of digital marketing. It stands exactly where content meets AI-powered analytics meets psychology. But, before I give you the details, here are some interesting statistics: Since its humble start in 2016, the global influencer market is expected to grow into a $32 billion industry by 2025. This shows how the industry has already started changing the way brands create credibility and value.

This article, Influencer Marketing in Numbers: Key Stats , is a collection of the most recent statistics that are influencing the industry. It discusses everything from budget and market size growth to the regions and tiers driving spend, the platforms where brands focus, and even the role of engagement, trust, and AI in the new definitions of influence and measurement. I thought it would be interesting to dive into a few of these stats here, relating them to other AI-related trends.

Global Influencer Marketing Market Size (2016–2025)

*2025 is an industry estimate/projection. Figures compiled from Influencer Marketing Hub’s benchmark series; various reports cite the same historical data and 2025 forecast.

Why it’s significant for AI

From where I sit, it’s really two developments driving most of the growth. On the demand side, the distribution function moved upstream, as creators are now the primary discovery channel for many product categories.

On the supply side, measurement got more precise, as lookalike modeling, content-level attribution, and AI-powered creator matching reduced waste and put finance chiefs at ease with bigger payouts.

The expected 2025 bump isn’t just “more content.” It’s a function of software that automates campaign briefs, content brand-safety review, content editing, and campaign optimization, much of it fueled by AI-native in influencer platforms and measurement platforms.

Going forward, I’d anticipate that spending will further concentrate on smaller sets of better-matched creators, with AI handling the gruntwork while humans handle narrative and relevance.

A broader economic slowdown or major platform-level disruption (policy changes, increased disclosure requirements) may slow it, but I believe the broader shift to creator-based distribution is a sustaining trend.

While the global rate of spend gets all the attention, there are interesting insights to be gleaned from looking at where the money is being spent around the world. Spend will be skewed towards North America, Western Europe and Asia-Pacific in 2025, with the US the biggest market, where spending on creator content will top US $10 billion alone.

Here are estimates for 2025 spending by region:

Data notes: The North America figure is underpinned by the US figure of ~US $10.52 billion. All other regions are estimated by applying historical regional breakdowns and growth rates to the global forecast (which is ~US $32 to 33 billion), as full regional breakdowns are not publicly available.

My analysis

In my view, there are three things to note:

1. In the developed world, concentration remains high. North America’s dominant share means that innovations, such as AI-enabled influencer-matching platforms, creator commerce models, and performance attribution tools, will continue to emerge there first and then diffuse globally.
2. There’s still growth to be had in the developing markets. APAC and LATAM are expected to see growth and could be regions where brands start to spend more in the next few years, driven by younger demographics, a strong mobile-first user base, and relatively unsaturated influencer-ad ecosystems.
3. Maturity begets measurement. Markets like North America and Western Europe already have substantial budgets allocated to the channel, and now the focus is on measuring and optimizing for maximum return on investment, building durable relationships with creators, and driving business outcomes. This means the era of explosive growth is likely over and we’re moving into an era of refinement, fewer, more targeted brand collaborations and more thoughtful investments in creators. In other words, that 2025 figure is big, but the regional distribution tells us where brands will double down, and how the channel will shift from reach to results.

Average Brand Spending on Influencer Campaigns (2024–2025)

I’m often asked how much brands are budgeting for influencer marketing campaigns and I’m happy to share that at the highest level, overall investment is growing and becoming more thoughtful.

In 2024, the average spend per brand on an influencer marketing campaign is not something I have seen published. However, I can share that on average, businesses are making US $5.78 for every US $1 they are spending on an influencer campaign.

In 2025, the average spend per campaign isn’t something I have seen reported. However, I do know that on average, the cost per acquisition (CPA) across the various platforms has declined by an average of 19.2 %, which is a good sign of optimization. In addition, I do know that many brands are committing a larger percentage of their budget to working with creators. Some are committing upwards of 20 % of their overall marketing budget towards creator collaboration.

With those data points in mind, I am going to provide an estimated average spend per campaign for a brand in a large market for a full scale test (as opposed to a micro-test):

*These are estimates based on industry benchmarks, growth rates, and cost-per-activation trends, not exact industry averages.

Analyst’s Take

In my opinion, the takeaway here is less about the number and more about the mindset.

Brands aren’t just spending more, they’re expecting more and want to use their dollars more efficiently.

The reality that cost per activation is decreasing while average budget ranges are increasing indicates that brands are becoming more efficient: more deliverables, better fitting creators, and greater measurement.

For marketers, this means it will no longer be acceptable to “do a million-dollar influencer campaign.”

It will be important to assess the structure of the spend, the split between creator fee versus content creation, how relevant the influencer is to your brand, how attribution is accounted for, and how AI-powered technology assists with campaign management and measurement.

This trend also signifies that smaller budgeted brands can play in the space by activating micro-influencers and staying under the average budget ranges, while larger budgeted brands will need to ensure that their larger budgeted campaigns deliver on long-term engagement and ROI.

Influencer Tiers by Follower Count (2025)

When it comes to measuring the effectiveness of an influencer in 2025, one of the best ways to tell which tier they are in is still the engagement rate (ER). In 2025, it is no longer just about the number of followers an influencer has, but also about how well they engage that audience.

When I looked at some of the recent benchmarking data, I noticed that on the whole the smaller the tier of influencer, the higher their average engagement rate will be.

Below is a rough outline of the estimated engagement rates for each of the key influencer tiers:

*These engagement rate numbers are estimates, they are averaged across both Instagram and some TikTok and are based on industry benchmarking data from 2025

Analysts Take

In my view there are 3 clear things to note here:

1. The smaller the audience, the higher the engagement rate. According to the table above you can see that on the whole, nano and micro-influencers have the highest engagement rates.
2. Brands are now understanding more and more that the smaller the audience, the higher the engagement rate will be. Engagement rate is measured in likes, comments and saves etc and generally speaking, the smaller the audience the more they will engage with the content.
3. Size isn’t everything. Sure, mega-influencers can offer reach, but the engagement rate is relatively low the higher you go up the tiers.
4. That is not to say they do not offer value. Sometimes brands want to work with mega-influencers for the reach but also for brand reputation and brand awareness, they do not always care about engagement rate.
5. Engagement rate is no longer everything. Since the introduction of AI filtering for audiences and the rise of Reels, TikTok and Stories, brands now want to see watch time, swipe up rates, conversions and even the quality of the audience.
6. Working with an influencer who has a good engagement rate but the wrong audience will not always generate the best results.
7. My advice would be to always use this benchmark as a minimum, then filter on relevance, content type and results.

Takeaway

So there you have it, if you are planning on running some influencer marketing campaigns in 2025, my advice would be to use these engagement rate benchmarks as a starting point to filter out the best influencers for your brand, but don’t stop there.

The best results will always come from a campaign where an influencer has a good engagement rate but also a relevant audience, creates content in a relevant format and drives results for your brand.

Engagement Rates by Influencer Tier (2025)

If you’re considering reach vs resonance this year, engagement rate (ER) is still the best indicator of the “vibrancy” of an audience.

As expected, it’s a function of audience size: ER is highest for smaller creators and lowest for larger ones. 2025 industry benchmarks are listed below for Instagram, and third-party studies have consistently found the same relationship.

Keep in mind: a 2025 survey that isn’t shown here pegs the average ER on Instagram for different levels of creators between ~1.77% and 3.65%, depending on audience size (with smaller creators averaging higher rates, and larger creators lower rates.) Use this as a reference if your vertical averages vary from the above chart.

Analyst’s take

In my opinion, the real story of 2025 is that content type and audience fit are now nearly just as important as audience size. As always, if you’re seeking engagement, I recommend starting with nano and micro creators; their audiences are more like groups than audiences.

However, ER is no longer the best indicator: completion rate and clickthrough rate for short-form content, audience quality, and the time from post to conversion are all critical in determining success.

If you’re after engagement and saves, favor nano and micro creators; if you want cultural relevance, macro and mega creators can still be valuable partners, just consider them for brand awareness and assisted conversions rather than engagement.

In other words, use the chart above to filter your partner list, then use objective, content type, and quality to finalize your list.

Top Social Media Platforms Used for Influencer Marketing (2025)

Let’s now jump to 2025, and look at which channels brands are actually spending their influencer marketing budgets on. Well, as you can see from the graph below, there are a lot of other options, but these three are the most desirable, and the numbers back that up. Source: Influencer Marketing Benchmark Report 2025.

According to our research, when asked which channel they prefer for influencer marketing, 57% of brands said Instagram. Second place is TikTok (52%), followed by YouTube (37%). Source: Influencer Marketing Benchmark Report 2025.

Analyst’s Perspective James

“My interpretation of this data is that it’s no longer just about the size of the audience. Brands are now considering who their target audience is, what type of content they want to create, and their e-commerce offering too.

“The reason why Instagram comes out on top is because not only can you reach mass audiences via its creators but it’s also highly shoppable through its features such as Reels, Live and Stories.

“Second place goes to TikTok. Here, brands are looking to capitalize on its trendiness and appeal to a younger audience. If you’re a brand looking to stay topical and gain brand awareness, TikTok is a good bet.

“Third place goes to YouTube. This is the go-to channel for brands when they’re looking to create longer form, review-style content.

“My key takeaway from this data is to not ignore the platforms which rank in fourth position and below, such as Facebook and LinkedIn. Yes, they might not be as sexy as the top three but they still offer huge value to brands targeting a B2B audience, or older generations and for those with more niche products.”

Most Popular Influencer Niches (2025)

As I look at the state of the influencer marketing world in 2025, the influencer niches that are trending and growing in demand are revealed. Below are the most in demand niches from both brands and creators according to the most recent industry reports. As you can probably guess health & wellness, tech & AI, beauty & skincare and personal finance are staples on the list.

2025 Most In Demand Niches:

The good news is that 2025’s in demand niches aren’t random. In fact, they all share a common thread. They are authentic, they represent a change and they are relevant. For instance, health & wellness isn’t about fitness anymore. It is about mental health, holistic wellness, longevity, and more. Tech & AI isn’t about unboxing products anymore. It’s about how AI is impacting work, content, and life.

My prediction and advice to brands is two fold. First, find a niche that aligns with your brand values. Don’t just hop onto a niche because it’s trending if it doesn’t align with your values. Secondly, attack the niche from a futuristic lens. If you are a beauty brand, what about eco friendly? How does diversity play a role? How does the intersection of beauty and health play a role? If you are a finance brand, what about TikTok explainers? Instagram live Q&As? Investment games for Gen Z?

The bottom line is that these are the most popular niches of 2025 for a reason. They represent what we care about, what’s new and emerging in tech and how we live our lives. However, just because a niche is popular doesn’t mean that it is going to work. The brands (and creators) that will be successful are those that will create trust, education, and relevance not those that just hop on the bandwagon.

Consumer Trust and Purchase Intent from Influencers (2025)

Influencer marketing is ever-changing and looking ahead to 2025, one thing is still true: there is a direct correlation between trust and purchase intent. It’s not a magic bullet and it’s not 100%, but it exists. According to new data, here’s what we know about how consumers trust influencers, the likelihood of them purchasing off their recommendations and how it’s changed over time as more brands work with influencers.

Two things can be true at the same time. This new data can be sliced two different ways. When we look at it one way, we can see that when it comes to purchasing, when consumers trust an influencer, they are more than likely to buy from them. In fact, 68% of consumers say they are more likely to buy based on an influencer recommendation and 54% say they have done so in the past. That’s no small number. To me, it shows that influencer marketing can still influence purchase behavior.

But there’s another way to look at the data. And it’s not as rosy. Although trust is a good start, just because someone trusts an influencer, it doesn’t mean they are buying from them. When we look at the numbers, 69% of consumers trust the recommendations of influencers, but only 58% say they have actually done it at least once because of an influencer. Furthermore, only 45% say they buy “often” off the recommendations of influencers.

Here’s what I would take away from this data if I was consulting a brand looking to do influencer marketing today. It’s all about trust. You have to build trust with your target audience. To do that, find the right influencers for your brand and product. When they give a recommendation, make sure it makes sense and it’s not forced. Then, make it easy for consumers to buy. Give viewers an easy next step, whether that’s a link, a code, or a clear landing page. Otherwise, consumers will trust the recommendation, but may not take the next step. The data says yes, consumers trust influencers and yes, there is purchase intent behind the recommendations. But brands still have to work for it.

AI and Virtual Influencer Statistics (2025)

This report is more like a halfway house really. It looks at the state of the industry up to 2025, and well, virtual influencers are a thing. What was once a bit of a gimmick has started to make inroads into the creator economy.

After all, the global virtual influencer market is projected to increase from around $7.94 billion in 2024 to $11.26 billion by the end of 2025, with a compound annual growth rate (CAGR) of 41.9% between them. Not bad.

But it’s not just brands that are taking notice. Consumers are already on board. 58% of social media users follow at least one virtual influencer, so we can tell that virtual creators are getting pretty normalised.

Anyway, here are some stats that are currently defining the industry in 2025:

I’ll just pick out a few of these that I think are pretty interesting and run through them.

Firstly, it’s pretty clear from that market size that brands are starting to take virtual creators pretty seriously. That’s quite a big leap from under $8 billion to over $11 billion in a year, and it tells me that brands are allocating budget to these sorts of channels and are exploring ways to work with them.

Secondly, while 58% of social media users might follow at least one virtual influencer, that doesn’t mean that they actually trust them as much as they trust human creators. I think there’s still a bit of a novelty factor at play here. People might like the content they create, but I think they still see them as somehow separate to human influencers. I think there’s still a big gap when it comes to authenticity and credibility, and that could have an impact on their ability to actually influence purchasing decisions.

Thirdly, I think for brands the big win could be in using both virtual and human influencers in the same campaign. Virtual influencers are great because you can control exactly what they say and do, they will never go off script, and they will always deliver your messaging in line with your values. But human influencers bring an emotional connection to the table that I’m not sure virtual influencers currently match. Combining the two could be a big winner, rather than pitting them against each other.

Finally, we need to remember that when it comes to growth this fast, there will be teething problems. If virtual influencers become too popular too quickly, we could see a big oversaturation of the market that would lead quality to drop and could see consumers start to get a bit fatigued. There are also questions around the ethics of virtual influencers if they’re not clearly labeled as such. I think these will become more important as the industry continues to expand.

If I was planning a campaign tomorrow, I’d definitely consider virtual influencers as part of the mix, but I wouldn’t abandon human creators altogether. I’d use them as a tactical tool where they make sense, and I’d test and learn to see what works and what doesn’t.

On the whole though, AI-powered influencers are coming to the fore in 2025. Done right and used in clever ways, they clearly have a lot of potential. But if brands start to use them as a direct replacement for human creators, I think we might start to see things go a bit wrong.

Top Influencer Marketing Platforms and Tools (2025)

Ever look at those giant diagrams with dozens of marketing technology logos and think, Ok, but what do marketers actually use? Yeah you’re not alone. Take a peek at the 2025 state of the union and you’ll see the same trend. There are big enterprisy suites on one end. They’re designed for bigger brands, control, and compliance. On the other end you have scrappier tools for speed. They’re used for discovery, creator enablement, and campaign deployment. Speed trumps infrastructure. Worth noting that review sites and smaller research firms tend to cite the same tools. Whether it’s discovery, campaign management, measurement, or brand safety. You’ll see the same usual suspects.

Top tools & what they do best (2025)

Methodology: This table was compiled from 2025 buyers’ guides and category reports. Strengths highlighted are based on multiple mentions across reports and verified customer reviews.

How the data applies to AI-enabled teams

As an analyst, I can tell you there are two big trends in 2025. First, the platforms are mostly commoditized when it comes to AI-enabled capabilities. Nearly all of the top tools now offer AI-infused modules around discovery, fraud, brand safety, and audience targeting.

Natural language processing, computer vision, and predictive analytics are commoditized at this point. With that in mind, integration has become the variable.

The question is no longer, Do you offer AI? It’s now, How easily can your tool integrate into my broader stack? Governance capabilities, APIs, and data normalization are now becoming the key differentiators. In other words, how easily can I integrate this tool into my existing adtech and martech stack?

Second, measurement expectations have evolved. Marketers don’t just want engagement metrics. They want content performance data, SKU-level sales lift analysis, and some proxy for measuring audience quality beyond engagement rates.

In practical terms, that largely means the following. Bigger programs tend to gravitate toward platforms like CreatorIQ or Traackr for more advanced governance and standardized measurement across massive creator networks. At the same time, many direct-to-consumer and midmarket brands rely more heavily on GRIN, Aspire, or Upfluence for streamlining ongoing seeding programs and affiliate ROI.

If I had one piece of advice to share, I’d say this: define your operating model before selecting a tool. Are you running continuous or campaign-based programs? Are you focused on organic reach or paid media amplification? Affiliate programs or flat-fee partnerships?

Once you define that, it’s easier to find a tool that simplifies, and does not complicate, your workflow. By 2025, the term AI-powered isn’t a differentiator anymore. What matters more is whether the platform can effectively turn creator data, content performance, and commerce signals into measurement that your CFO can trust.

The big picture

Taking a step back from the platforms, a larger trend is emerging. Influencer marketing is no longer in its Wild West phase. It’s maturing into a more established media channel. There are clearly defined creator tiers.

Benchmarks for engagement. Geographic hubs for influencer activity. And a maturing software stack to support it all. AI is playing a silent role, from discovery algorithms and fraud detection to attribution modeling and the rise of virtual creators. As spend levels increase and tools become more sophisticated, the focus in the space is starting to shift from raw reach to driving purchase intent.

Brands that approach their influencer strategies with that mindset, focusing on relevance, authenticity, and long-term partnerships, will outperform those that are purely focused on scale. Ultimately, the state of the influencer marketing union in 2025 isn’t just about social media adoption continuing to increase. It’s about the convergence of AI, trust, and narrative, and how those factors are changing the concept of influence itself.
