It’s easy to take Instagram’s inter-decade success for granted. Over the 2010s, we saw the rise and fall of many different social media apps and websites all attempting to vie for supremacy in the zeitgeist, such as Google Wave, Google Buzz, Google+, Vine, Yik Yak, Ello, and more, yet there have been few apps in history with the longevity and influence of Instagram. So, when it comes to finding Instagram influencers and KOLs for your brand, it’s important to understand what makes the platform tick, and what you need to be looking for in order to make it work for your campaigns.
With Instagram’s 2 billion+ monthly active users in 2025, it’s a prime platform for brand promotion. However, selecting the right Instagram models or influencers for your promotional campaigns is critical to building authentic connections and driving results, and that isn’t always easy. The key is finding influencers who align with your brand’s identity, values, and audience. So, today, we’re going to break down our tips for discovering influencers, and share insights into the evolving Instagram influencer space.
The Instagram Influencer Landscape in 2025
Before you start selecting influencers for a campaign, you first need to look at the scope of the influencer ecosystem, as the term influencer can mean different things depending on the space you’re looking to target. After all, the influencer ecosystem on Instagram spans nano-influencers (1,000–10,000 followers) to mega-influencers (1M+ followers), each offering distinct benefits to brands looking to connect with them.
Nano-Influencers
1,000 – 10,000 Followers
High engagement (5–10%) with niche, loyal audiences. Ideal for targeted campaigns.
Micro-Influencers
10,000–100,000 Followers
Strong engagement (3–6%) and niche authority, perfect for relatable content.
Macro-influencers
100,000–1M Followers
Broad reach with moderate engagement (1–3%), suited for established brands.
Mega-influencers
1M+ Followers
Massive visibility but lower engagement (0.5–2%), best for high-impact awareness.
Authenticity Drives Success
A study conducted by Edelman shows 63% of users trust influencers over traditional ads, but only when partnerships feel genuine. Misaligned collaborations can erode trust, so influencers must complement your branding strategy—matching your aesthetic, values, and audience demographics.
Steps to Select Instagram Models
Setting Clear Campaign Goals
For any campaign, it’s important that you understand what it is that success means for you. After all, each brand will benefit from different things, and in the larger ecosystem of your marketing approach, not all actions are going to be directly to drive sales. Some of the different options for campaign goals include:
Brand Awareness
For brand awareness campaigns, prioritise influencers with larger followings. This will likely lead to a lower engagement rate, but will offer you a wider net. You can think of this like stretching out a piece of rubber; as the rubber expands, it has a wider surface area, but a thinner presence.
Engagement
Unlike brand awareness, engagement requires a more active following. Campaigns like these will therefore benefit from a focus on nano- or micro-influencers for likes, comments, or shares. These smaller influencers don’t have the same reach, but their closer-knit communities are often more actively engaged and more likely to interact with the promotions that you are creating with your chosen influencer.
Conversions
Whilst conversions are generally the end goal of any promotional campaign, getting an influencer’s audience to convert directly is a much more complex thing to achieve. After all, it relies on the influencer to act as a true brand ambassador, selling your items directly. For campaigns like these, seek influencers with proven sales impact, often tracked via affiliate links or promo codes.
Knowing Your Audience
Your influencer’s followers should mirror your target market. Use tools like Lefty’s influencer marketing platform to analyse audience age, gender, location, and interests. For example, a fitness brand targeting young men should partner with influencers whose audience is predominantly male and active.
Aligning with Your Brand
Choose influencers whose content reflects your brand’s ethos. A luxury brand needs polished, high-quality visuals, while a streetwear brand might opt for raw, grungier aesthetics. Review their posts and Stories to ensure their tone, values, and style align. Avoid influencers who’ve worked with conflicting brands to prevent mixed messaging, and track the type of responses these influencers have received from previous promotional collaborations.
Analysing Engagement and Authenticity
Engagement rate (likes + comments ÷ followers) is more important than follower count. Look for organic interactions, not bot-driven metrics. Tools like HypeAuditor and Lefty can detect fake followers, a persistent issue for 25–30% of influencers. Aim for influencers with consistent, meaningful engagement.
Evaluating Content Quality
Assess the influencer’s visuals, captions, and storytelling. High-quality content is crucial for premium brands, while authentic, unpolished posts may suit casual or youth-oriented campaigns. Reels are particularly effective, as video content drives 70% more engagement than static posts in 2025.
Reviewing Past Performance
Request data from previous campaigns, such as reach, impressions, or conversion rates. Influencers with a track record of success are more reliable partners.
Negotiating Clear Terms
Discuss deliverables (e.g., posts, Stories, Reels), timelines, and compensation. Balance creative control with the influencer’s authenticity—overly scripted content can feel forced. Ensure compliance with advertising rules (e.g., #ad tags) to meet FTC guidelines.
