What Do Fitness Brands Look For In Micro-Influencers

1. Alignment with Brand Values

When searching for influencers, brands often prioritize when a creator’s philosophy matches their ethos. Their genuine match is what will make the collaboration feel authentic.

2. Reaching a Targeted Audience

One of the benefits of partnering with smaller creators is that brands have the ability to target a specific demographic as they specialize in specific niches. By exploring different categories within the fitness niche like bodybuilding, weight loss fitness, women fitness, pre/post natal fitness, and more, micro-influencers grow even more segmented audiences to build a relationship with.

3. High Engagement Rates

As one of the most valued KPIs for brands, engagement rates tend to scale for smaller creators. According to Favikon, micro-influencers have an Instagram engagement rate of 1% to 3%, whereas the macro-influencer rates fall between 2% to 5%. This difference reflects how bigger creators often lack the more personal connection smaller creators offer.

4. Cost-Effectiveness

When implementing influencer marketing on a budget, smaller brands tend to partner with smaller creators, as they have lower rates, delivering higher ROI. Additionally, micro-influencers are more likely to accept gifting or work on an affiliate basis, which makes them beneficial for brands with lower budgets.
