Vetting influencers really boils down to two schools of thought: the data-driven auditors who trust quantitative analysis, and the content-first curators who trust their own trained eye. Each side has a strong case, but the best approach for you likely involves combining the two.
Camp A: The Data-Driven Auditors
This camp believes in vetting influencers through rigorous, quantitative analysis. The core idea is that you can’t trust follower counts, so you must verify everything. Selene Dior, on an episode of the Serious Sellers Podcast, shared that her number one step is to ask creators for a screenshot of their Instagram Insights. This gives her direct access to their audience's demographics (age, gender, location) and a real look at their engagement, bypassing the risk of vanity numbers. This camp warns that many influencers buy likes and followers, so it's critical to perform what she calls "extreme screening." Proponents of this view use third-party tools like HypeAuditor to analyze follower authenticity and spot bots. Nadia Bubennikova from the 2X eCommerce Podcast also lands in this camp, emphasizing the need to look at an influencer's engagement rate and calculate the potential cost-per-mille (CPM) to ensure a partnership will be cost-efficient. The process is systematic, designed to mitigate risk and make the unpredictable nature of influencer marketing as predictable as possible.
Camp B: The Content-First Curators
This camp argues that starting with data is how you end up with generic, uninspired partnerships. Instead of databases and spreadsheets, they believe the best vetting tool is your own deep understanding of your brand and customer. On Ecommerce Coffee Break, Andy Cloyd argued that the brands who are truly crushing it take a more personal approach, using a 'trained eye' to discover compelling content on social platforms. It’s an intuitive process based on a simple question: does this creator's content feel right for our brand? Nik Sharma made a similar point on Limited Supply, explaining that he starts his search by looking for gifted storytellers, often smaller vloggers on TikTok and YouTube who are naturally good at speaking to a camera. This approach prioritizes authenticity and storytelling ability over raw numbers. Shibo Xu even suggested on Honest Ecommerce that a great place to start is by looking through your own customer list to see if any of your actual customers are already micro-influencers. The focus is on finding a true, authentic connection first.
I believe the content-first curators have it mostly right, but with a critical caveat. You should absolutely start with the content and the 'vibe check'. No amount of data can fix a partnership with a creator whose style clashes with your brand's values. An influencer who is a genuine fan and a natural fit will create content that feels authentic and converts, which is the heart of a successful influencer marketing strategy. However, once you've found a creator you're excited about, it's foolish not to use the tools of the data-driven auditors to verify your gut feeling. This hybrid approach—find the fit, then check the facts—gives you the best of both worlds. You get the authentic connection of Camp B, with the risk mitigation of Camp A. You should ask them to send us their insights, just to make sure their audience is who you think it is.
So, what should you do? If you're just starting and your budget is small, lean heavily into the content-first approach. Your time is your best asset. Manually search for and build relationships with micro-influencers who genuinely love your niche. The risk is low, and the upside of finding a true brand advocate is enormous. If you're a larger brand looking to scale, your process will look more like the hybrid model. Use your 'trained eye' to develop a clear persona of your ideal creator, then use data and analytics tools to find more people who fit that profile. At scale, you can't rely on serendipity alone. You need a system to ensure your investment is sound.
