Scroll through Instagram in Slovenia this September 2025, and a pattern emerges: creators are moving beyond curated perfection toward real conversations and measurable impact. From fashion to fitness, authenticity ruled the feed — and brands paying attention are already reaping the benefits.

Key Metrics for September 2025

September marked a renewed rise in branded collaborations, with 716 sponsored posts circulating among Slovenia’s creators. This is a 1.2% increase after a period of decline over the summer months. This uptick may signal a calm before the storm of Q4, as brands begin ramping up campaigns ahead of the holiday season. Yet, despite the surge in activity, the average engagement rate remained below 1%, pointing to a persistent challenge: audience fatigue.

While likes and comments held steady, the 28% collaboration saturation suggests that influencer content is becoming increasingly commercialized. Still, this doesn’t mean audiences are tuning out entirely — rather, they’re becoming more discerning, engaging most with creators who maintain authenticity, consistency, and genuine storytelling amid frequent brand partnerships.

Trends and Patterns

Distribution by Influencer Size

Even though macro influencers represent only about 10% of all active creators, they were responsible for 19.41% of sponsored content in September, nearly double their share by volume. This shows that while smaller creators dominate in numbers and drive authenticity through closer audience connections, larger influencers still play a crucial role in delivering visibility, reach, and brand credibility. For most brands, the most effective strategy lies in combining both. Using nano and micro creators to build trust and engagement, and macro influencers to amplify awareness and campaign impact.

Photo vs. Video Performance ans Giveaways

When comparing formats, photo posts achieved an average engagement rate of 2.70%, outperforming video posts at 1.57%. A 41.92% higher engagement in favor of static content. But there’s a catch. The elevated performance of photo posts is largely driven by giveaways, which made up 16% of all sponsored posts in September and achieved an average engagement rate of around 4%. It’s a familiar trend: giveaway posts consistently dominate engagement charts, and September was no exception. With the top two posts of the month both being giveaways that generated exceptionally high interaction rates.

Top Brands Collaborating with Influencers

Some of the most active advertisers in September included:

Advertisers activated 343 influencers in September. Big retail and lifestyle brands continue to invest heavily in influencer marketing, focusing on consistent visibility rather than one-off collaborations. However, results still depend on matching the right influencer to the right campaign, not just on volume.

Actionable Recommendations for Brands

1. Use a balanced mix of nano, micro, and macro influencers
   • Nano for authenticity and community engagement
   • Micro for reach within specific niches
   • Macro for large-scale awareness and credibility
2. Invest in high-quality creative production
   • Great visuals, consistent branding, clear CTA
   • Authentic storytelling drives more comments and saves
3. Analyze anomalies and learn from them
   • Identify creators performing above the trend line
   • Study their tone, timing, and audience interaction
4. Track metrics over time — not just likes
   • Monitor engagement rate, comments, reach, and content mix
   • Compare performance month-to-month to detect seasonal patterns

Conclusion

September 2025 painted a clear picture of a maturing creator economy in Slovenia. The data shows an active market, but with growing signs of selectivity and saturation. Engagement levels remained stable yet below 1%, signaling that while influencer marketing remains powerful, audiences increasingly reward authenticity and meaningful storytelling over frequency alone.

As Slovenia heads into Q4, brands that will stand out are those that strategically blend data-driven planning with human connection. Nurturing long-term partnerships, refining creative quality, and aligning with creators who embody real influence rather than just follower counts. The next wave of success won’t come from doing more, but from doing it smarter, more authentically, and with the audience at the center.
