Tomoson Influencer Marketing Study: Findings & 2026 Lessons

TL;DR: The Tomoson influencer marketing study is a 2015 survey of marketers that reported an average return of $6.50 for every $1 spent on influencer marketing, with top performers earning $20 or more. Its headline number is dated, but its core lessons — returns are skewed toward systematic brands, and micro-creators punch above their weight — still hold in 2026.

Few pieces of marketing research get quoted as often as the Tomoson influencer marketing study. One dollar figure — $6.50 earned per $1 spent — has shown up in thousands of agency decks, blog posts, and news articles over the past decade. Yet most people citing it have never read what the study asked, when it ran, or what its less famous findings were. Here's what it found, how seriously to take it in 2026, and what a modern brand should actually do with it.

What is the Tomoson influencer marketing study?

TL;DR: The Tomoson influencer marketing study is a survey of marketing professionals published in 2015 by Tomoson, an influencer and product-review platform. It asked marketers to self-report the revenue their influencer campaigns generated relative to spend, and its results were popularized by trade press coverage, most famously the $6.50-per-dollar ROI headline.

Tomoson is a US-based platform that connects brands with influencers and product reviewers. In 2015, the company polled marketing professionals on how influencer marketing performed against their other acquisition channels. The answers were striking for the time. Respondents said influencer marketing was their fastest-growing online customer-acquisition channel — ahead of organic search, paid search, and email in growth terms — and that the customers it brought in were often higher quality than those from other channels.

The finding that traveled furthest was the ROI figure. On average, respondents said they earned $6.50 in revenue for every $1 invested in influencer marketing. Adweek and other outlets ran the number, and it became the industry's default proof point — the stat you reached for whenever someone asked, "does influencer marketing actually pay off?"

Be honest about what the study was: a self-reported survey of a limited pool of marketers, run by a company with a commercial interest in the answer. That doesn't make it worthless. Early industry research almost always comes from vendors. But read the numbers as directional evidence, not scientific fact. For a broader primer before digging into the data, start with what influencer marketing is and how it works.

What did the Tomoson study actually find?

TL;DR: Beyond the famous $6.50 average, the study found that returns were heavily skewed — a top slice of businesses earned $20+ per dollar while others broke even or lost money — that marketers rated influencer-acquired customers as higher quality, and that most planned to increase influencer budgets.

The findings cluster into four themes, and the less-quoted ones are arguably more useful than the headline:

1. The average masked a wide spread. The mean reported return was $6.50 per dollar, but the distribution was far from even. The best-performing businesses reported $20 or more per dollar spent; a meaningful minority broke even or lost money. Influencer marketing wasn't a lottery ticket that paid everyone equally. It rewarded brands that ran it well and punished those who treated it as a one-off stunt.

2. It was the fastest-growing acquisition channel. Respondents ranked influencer marketing as their fastest-growing online customer-acquisition method — ahead of organic search, email, and paid search. In hindsight, this was the study's most prophetic finding. It caught the exact moment influencer marketing shifted from novelty to core channel.

3. Customer quality mattered as much as volume. Roughly half of the marketers surveyed said customers acquired through influencers beat customers from other channels. They trusted the brand from day one, because the recommendation came from a person, not an ad.

4. Budgets were about to move. A majority of respondents planned to increase influencer marketing spend the following year. Multiply that intent across the industry and you get a big part of how influencer marketing grew into the multi-billion-dollar category it is today.

Is the $6.50 ROI still realistic in 2026?

TL;DR: As a universal promise, no — the study is a decade old and the market has professionalized. But the underlying pattern holds: brands that pick relevant micro-creators, negotiate content usage rights, and reuse UGC across ads and product pages routinely outperform their paid-media benchmarks, while brands chasing vanity reach underperform.

A lot has changed since 2015. Creator prices rose. Disclosure rules tightened. Audiences got savvier about sponsored content, and short-form video replaced the blog posts and static Instagram photos of the study's era. Quoting $6.50 as a 2026 guarantee is exactly the kind of fabricated certainty that gets marketers in trouble.

Here's how the landscape the study measured compares to the one you're operating in now:

The honest 2026 takeaway: ROI is *earned*, not inherited from an industry average. If anything, the skew the study found has widened — the gap between brands that run creator programs systematically and those that dabble is larger than ever. For the deeper argument on why the channel still works, read why influencer marketing remains so effective.

What the study got right: small creators, real trust

TL;DR: The Tomoson study's most durable insight is that trust — not reach — drives influencer ROI. That insight explains why micro-influencers and UGC creators, who trade celebrity scale for genuine audience relationships, have become the highest-ROI segment of the industry.

The study measured a world where most "influencers" were bloggers and mid-sized social accounts, not celebrities. The strong returns respondents reported came largely from these smaller, trusted voices — people whose recommendations felt like a friend's tip, not a billboard. A decade on, that pattern has a name and a body of practice: micro-influencer marketing.

What that means for a brand planning campaigns today:

• Prioritize relevance over reach. A creator with a modest but engaged local or niche audience typically converts better per euro than a large account with a diluted one.
• Work with many creators, not one. The study's skewed returns argue for treating influencer marketing as a portfolio. Ten small collaborations give you ten shots at a breakout piece of content. One big deal gives you one.
• Negotiate content usage. Much of modern influencer ROI comes from *reusing* creator content — in paid ads, on product pages, in email. The post itself is often just the first touchpoint.
• Track something. Discount codes, UTM links, and post-purchase "how did you hear about us?" surveys turn the study's self-reported guesswork into numbers you can actually manage against.

How to get study-level ROI for your e-shop or business

TL;DR: To replicate what the study's top performers did, run a repeatable program: brief multiple vetted creators, offer product or paid compensation, secure usage rights, and recycle the resulting UGC across your ads and store. A creator platform makes this workflow fast enough for even a small team to sustain.

If you run an e-commerce brand, restaurant, hotel, or local business and the study convinced you to try creator marketing, good news: the barrier to entry is lower than it was in 2015. No agency retainer required. No celebrity budget either.

A simple, repeatable setup:

1. Define the outcome. Reach on the creator's channels, UGC for your own ads, or foot traffic and orders? Each goal shapes the brief.
2. Choose your compensation model. Barter (products, meals, stays) works remarkably well with micro-creators; paid campaigns make sense when you need guaranteed deliverables and full usage rights.
3. Brief several creators at once. Give each one your key message and creative freedom on execution. Authentic delivery is the entire point.
4. Collect, license, and reuse the content. The video that performs on a creator's profile usually performs even better as your paid ad or product-page asset.
5. Measure and repeat monthly. Keep the creators who convert, replace the ones who don't, and let the portfolio compound.

This is the workflow platforms like CreatorPass are built around: brands and local businesses across Central Europe connect with 1,000+ vetted content creators for barter or paid collaborations and get usable UGC without managing outreach spreadsheets. If you'd rather run one campaign a month than fifty DM threads, see how it works for businesses.

How should you cite the Tomoson study today?

TL;DR: Cite it as a historical milestone — the first widely publicized attempt to quantify influencer marketing ROI — and pair it with the caveat that it's a 2015 self-reported survey. Use its structural findings (skewed returns, customer quality, small-creator advantage) rather than its exact dollar figures.

The Tomoson study earned its place in industry history. It gave marketers a number when they had none, and it correctly predicted that influencer marketing would become a mainstream acquisition channel. But a decade on, quoting "$6.50 for every dollar" as a current fact undermines your credibility with any audience that checks sources — including AI search engines, which increasingly favor content that dates and contextualizes its statistics.

The smarter move in 2026 is to generate your own numbers. Run a small, structured creator program. Track codes and links, calculate the production value of the UGC you receive, and compare the blended result to your paid-media benchmarks. Do that for a quarter and you'll have an ROI figure worth infinitely more than any decade-old survey average — because it's yours.
