Posting More Sponsored Content Doesn't Cost Creators Their Audience, New Kolsquare Data Confirms

Creators who post more branded content lose fewer followers than creators who post none at all; a pattern that holds across major markets and creator tiers, new data from Kolsquare shows.

TABLE OF CONTENTS

The question of whether posting sponsored content is a turn-off for audiences has been laid to rest. New analysis from Kolsquare of some 863,000 creators’ followings across Europe’s five largest markets shows creators who post more sponsored content lose fewer followers than creators who post none at all.

Covering creators across France, Germany, Italy, Spain and the UK during a six-month period, the pattern holds market by market, not just on average. The data proves it: the so-called “influencer recession” isn’t as widespread as the headlines would have you believe.

“This new data shows that audiences not only reward creators for transparency, but they even expect creators to collaborate with brands as a natural part of their creator activity,” comments Kolsquare Founder and CEO Quentin Bordage. “It’s a measure of how the industry on both sides has matured. Audiences understand that their favorite creators need to make a living from their content, and creators today understand that transparency trumps trickery in the long game.”

The finding builds on earlier analysis from Kolsquare, which found that correctly disclosing sponsored content is not a negative barrier to performance on engagement and EMV (earned media value) metrics.

Follower loyalty and sponsored posts: the full picture

Kolsquare tracked 862,534 creators with at least 30% of their audience based in each of the five markets, on Instagram and TikTok, from Jan. 1 to June 30, 2026. For each creator, the analysis compares follower count at the start and end of time period and flags any net loss as a loss of followers. Averaged across the five markets, the follower loss rate drops at every step as sponsored-post volume rises:

# of sponsored posts published Europe, average follower loss rate
0 44%
1 31%
2-3 27%
4-9 24%
10-19 21%
20-49 21%
50-99 21%
100-149 17%
150-199 12%
200 or more 9%

Creators who post no sponsored content at all lose their followers nearly five times as often as the most prolific posters hold onto theirs. The gain in loyalty is steepest in the first few posts and then levels off into a plateau through the double digits, before improving at the highest volumes tracked (150 or more sponsored posts in six months, a pace only a small number of full-time creators sustain).

Follower loyalty by account size and sponsored post volume

Account size matters too. Combining the five markets into a single weighted table, split by both follower tier and sponsored-post volume, shows the pattern holding steady almost everywhere.

Follower tier 0 sponsored 1-3 sponsored 4-9 sponsored 10+ sponsored
Nano (0-5k) 34% (108,057) 21% (22,569) 18% (8,536) 13% (7,611)
Micro (5k-100k) 46% (489,337) 31% (92,578) 24% (34,830) 22% (31,203)
Macro (100k-1M) 48% (31,465) 37% (13,908) 29% (9,068) 23% (8,670)
Top (1M+) 23% (1,576) 24% (1,251) 22% (986) 23% (889)

Cell values are the follower loss rate, with the number of creators (not posts or followers) analyzed in that cell in parentheses.

Notably, follower loyalty improves at every step up in the volume of sponsored content for nano, micro and macro creators, the same pattern reported at the European level overall. A macro creator with zero sponsored posts loses followers at a rate of 48%, compared with 23% for one who posts 10 or more, cutting the loss of followers roughly in half.

Across the top tier, creators with 1 million or more followers, the pattern is challenged. The follower loss rate here remains flat regardless of volume, at 22% to 24% across the band. This cohort has the smallest data population by far, so the flat rate should be read as a data-limitation exception rather than a reversal of the trend.

These findings cut against a very different narrative that has dominated creator economy coverage during the summer 2026, one that goes by different names depending on the market: an “influencer recession” in US coverage, “la caída de los influencers” (the downfall of influencers) in Spain, and what the French outlet L’ADN called “une grosse fatigue” (a huge fatigue). The specifics vary by market, but the shape of the story does not: tightening brand budgets, audiences increasingly irritated by displays of wealth, and a particular exhaustion with the generic aspirational-lifestyle format many creators have built their following on.

None of that shows up in this data as a rejection of sponsored content itself. The recession narrative describes fatigue with a specific tone and format, generic luxury and overproduced lifestyle content disconnected from reality, more than with branded partnerships as a category.

And unlike TV or display advertising, creator-led brand content sits inside a relationship a follower already opted into; frequent, well-executed collaborations can read as evidence of a creator’s professionalism and staying power rather than a sales pitch.

How the countries compare

The pattern is identical everywhere. The baseline differs.

Italy and the UK start the highest. Creators with zero sponsored posts lose followers at a rate of 47% in Italy and 46% in the UK, the worst retention of the five markets. France starts lowest. Zero-sponsored-post creators in France lose followers at a rate of 39%, still the strongest loyalty baseline in the dataset even before any branded content enters the picture. Germany and Spain sit in between, at 41% and 45% respectively.

Sponsored posts published France Germany Italy Spain UK
0 39.1% 41.3% 46.7% 44.6% 46.1%
1 27.2% 32.7% 32.2% 30.7% 33.0%
2-3 24.5% 29.6% 29.3% 25.7% 29.6%
4-9 21.4% 26.1% 26.6% 23.3% 24.0%
10-19 18.0% 23.3% 23.9% 20.4% 21.8%
20-49 17.2% 21.2% 25.6% 21.5% 20.6%
50-99 18.1% 23.3% 26.6% 20.9% 17.5%
100-149 14.8% 17.6% 22.2% 17.2% 14.2%
150-199 6.8% 19.1% 17.3% 6.5% 11.4%
200 or more 8.9% 15.9% 9.6% 2.9% 6.2%

By the time creators reach 20 or more sponsored posts, the gap between markets narrows sharply. Spain drops to a 2.9% follower loss rate at 200-plus posts, the lowest endpoint recorded anywhere in the analysis.

The data clearly establishes that posting more sponsored content and holding on to followers consistently move together. The fear of "sponsorship fatigue" driving audiences away is unfounded.

"This is the first time we've been able to prove, at this scale and across five major markets, that responsible sponsored content builds audience trust rather than erodes it," commented Kolsquare Founder and CEO Quentin Bordage. "For years the industry has treated disclosure and volume of collaborations as risks to manage. Our data shows the opposite: creators who post more, and post transparently, are the ones their audiences stay with. That's the case for more volume of collaborations in the industry, with a responsible approach, made with data instead of intuition."

Disclosure of brand deals drives better performance

Confirmation that posting sponsored content does not negatively impact a creator’s following aligns with data Kolsquare released in April 2026 showing that content that complies with transparency regulations often drives stronger campaign performance.

Clear advertising disclosure, regulatory compliance and transparent brand partnerships are increasingly seen as essential components of credible creator marketing. Yet a persistent concern among brands has long been that transparency could reduce performance by making promotional content feel less authentic.

Kolsquare analyzed 1.33 million pieces of content published by some 617,000 KOLs (Key Opinion Leaders) to test whether disclosure of commercial collaborations comes at a performance cost on engagement rate and EMV (earned media value) metrics.

Kolsquare’s Europe-wide data shows disclosed content wins where it counts most: amongst creators with 5,000-50,000 followers which as a group, publishes the largest volume of sponsored posts by far. Here, transparency compliant content beats non-compliant on both engagement and EMV (earned media value).

Beyond that tier, the picture is flat on engagement for performance of content amongst creators with upwards of 50K followers, and similarly flat on EMV for creators in the 50K-1M follower band.

Kolsquare’s proprietary Compliance Score algorithm determines and ranks content against national advertising SRO recommendations for disclosure of brand partnerships in sponsored content.

Broken down by market, the differences reveal much about local nuance, complexity and the maturity of influencer marketing in each country.

France is a clear pro-compliance market. Disclosed posts beat undisclosed content on EMV across every tier. On engagement, correctly disclosed content wins in the three tiers that make up the bulk of the market, 5,000 to 1 million followers, though it loses at the very smallest and very largest ends.

FRANCE

Follower tier Sponsored posts Sponsored ER Compliant ER Non-compliant ER Sponsored EMV Compliant EMV Non-compliant EMV
0-5k 40,712 3.61% 3.64% 3.75% 258 294 251
5k-50k 143,098 2.19% 2.83% 1.91% 852 981 838
50k-100k 33,315 0.90% 1.16% 0.81% 2,543 2,784 2,571
100k-1M 57,450 0.78% 0.86% 0.77% 7,127 8,554 6,482
1M+ 6,430 0.29% 0.27% 0.33% 31,787 32,897 32,527

In Germany, there is a disclosure penalty concentrated at the smaller end of the market, but not one that has a fixed cost that scales with a creator's size. At the smallest end, the gap is stark: undisclosed posts among nano creators post a 3.95% engagement rate against 2.51% for disclosed content, and pull in nearly double the EMV. By the time creators reach 100,000 to 1 million followers, that gap has all but closed, 0.71% versus 0.64% on engagement, 7,459 versus 7,412 on EMV, a difference too small to call a meaningful business decision.

GERMANY

0-5k 40,140 2.59% 2.51% 3.95% 184 164 314
5k-50k 170,664 1.56% 1.63% 2.02% 728 705 873
50k-100k 33,668 0.71% 0.70% 1.00% 2,153 2,156 2,639
100k-1M 61,139 0.59% 0.64% 0.71% 6,764 7,412 7,459
1M+ 3,849 0.52% 0.47% 0.48% 34,771 30,508 31,299

In Spain compliant posts win on engagement for content posted by creators with 5,000 to 100,000 followers, and on EMV for 5,000 to 50,000 followers — the categories where the bulk of the content is published. On EMV, disclosed content wins just once, in the 5,000-to-50,000 tier, and trails non-compliant posts by a wide margin at the top end, 34,025 versus 26,739 among 1 million-plus creators.

Autocontrol-certified creators show the same pattern: among certified macro creators (100K-1M followers), compliant content edges ahead on EMV, reversing the wider market's non-compliant lead in that tier. The non-compliant advantage for top creators (1M+ followers) shrinks 23 points to just 4%.

SPAIN (all creators)

0-5k 29,818 2.06% 2.04% 2.10% 159 156 161

1M+ 6,408 0.34% 0.25% 0.38% 31,787 26,739 34,025

In the UK disclosed content wins outright in the 5,000-to-50,000 tier on both engagement and earned media value, and pulls ahead again on EMV among the very largest creators. Where non-compliant content leads, the margins are tight, so the UK looks less like a market that punishes disclosure and more like one where it simply isn't the deciding factor.

1M+ 5,663 0.21% 0.17% 0.23% 22,473 25,187 21,390

Italy is more balanced than it first appears. Engagement is nearly identical across every tier, with the gap between compliant and non-compliant performance on this metric minimal, meaning disclosure isn't costing much either way. On EMV, disclosed content actually leads in three of five tiers, and by solid double-digit margins at the smaller and mid-sized brackets.

Alongside the follower loyalty findings, a two-part story emerges. Posting sponsored content tracks with better follower loyalty everywhere in Europe, no exceptions. Whether that content is properly disclosed also tracks broadly with stronger performance, but with stronger or weaker advantages according to each market.

FAQ

What are the most effective influencer marketing strategies for brands in 2025?

In 2025, the most effective influencer marketing strategies combine creativity, continuity, and analytical discipline. Brands are moving beyond one-off posts to build ecosystems of creators who amplify storytelling, drive engagement, and contribute to measurable performance.

One proven approach is to mix long-term partnerships with agile activations. Ambassadors and recurring collaborators help maintain authenticity and trust, while short-term campaigns boost visibility and support seasonal or product-specific goals. This “always-on” rhythm ensures consistent brand presence without audience fatigue.

A second key strategy is layered influencer engagement. Combining macro influencers for broad awareness with micro and nano creators for targeted credibility produces a more substantial ROI than relying on a single profile type.

Finally, brands that embrace AI and predictive analytics are gaining an edge. Platforms like Kolsquare enable teams to forecast performance, identify creators likely to outperform based on past data, and scale campaigns with precision.

The most successful marketers treat influencer marketing as an integrated media discipline: one that connects awareness to action, and creativity to accountability. When done right, it’s not just about reach, but about relevance, relationships, and measurable growth.

How can I measure the ROI of my influencer marketing strategy?

Measuring ROI in influencer marketing means connecting creative impact with business outcomes. Start by linking each campaign objective (awareness, engagement, or sales) to a clear metric. Common KPIs include cost per engagement (CPE), earned media value (EMV), reach, click-throughs, and conversions.

Use analytics tools to consolidate performance across platforms. Kolsquare enables marketers to track every stage of the funnel. From influencer output and audience interaction to website visits, leads, or purchases, Kolsquare make it easier to attribute results accurately. Integrating this data with your CRM or e-commerce analytics gives you a full view of creator impact.

When analysing results, compare organic vs. paid outcomes. Organic content demonstrates authenticity and brand affinity, while paid amplification extends reach and improves targeting efficiency. Evaluating both reveals the full value of each creator and content type.

Beyond short-term metrics, remember that ROI also reflects long-term brand equity: the credibility, trust, and loyalty that consistent, authentic partnerships create. Combining data precision with human insight allows you to measure what truly matters: influence that not only drives conversions but builds sustained growth over time.

What are the key steps to create a successful influencer marketing campaign?

A successful influencer marketing campaign starts with clarity. Before launching, map out your influencer campaign planning process and define SMART goals that specify what success looks like, whether it’s increasing awareness, driving conversions, or generating high-quality content. Then, map audience personas to understand who you’re trying to reach, which platforms they use, and what types of creators they trust.

Once your objectives and audience are clear, design a campaign narrative that aligns with your brand positioning. Choose content formats (short-form video, tutorials, product placements, or storytelling) that fit both the platform and the creator’s authentic voice. Consistency between your message and the influencer’s tone is key to credibility.

Next, select influencers using both qualitative and quantitative criteria. Look beyond follower counts to evaluate engagement, audience fit, and content quality. A mix of macro, micro, and nano creators often delivers the best balance between reach and authenticity.

Finally, track performance throughout the campaign lifecycle. Use KPIs like reach, engagement, EMV, and conversions to monitor progress and optimise in real time. Platforms like Kolsquare centralise all campaign data, from influencer contracts to performance dashboards, helping you stay agile and data-driven.

A strong campaign blends strategy, creativity, and continuous measurement, building not just visibility, but lasting relationships with audiences that convert.
