What are the KPIs of KOLs?

After Forbes recently announced this year’s list of top-earning YouTubers  , the conversation in the marketing world has turned to how best to measure the return on investment brands around the globe are putting into influencers and key opinion leaders (KOLs).

xAnother question for marketers to get to grips with is does size matter when it comes to selecting which influencer to work with? And what does this mean for B2B marketers and their global brand strategies?


7-year old Ryan made $22 million playing with his toys in the last 12 months. Yes, you read that right. $22 million. Playing with his toys! Regardless of how you feel about the rights and wrongs of this, by filming Ryan unboxing and playing with new toys, his parents have made him this year’s biggest YouTuber. He has over 17 million subscribers and his videos have been watched over 25 billion times. Most of his earnings come from pre-roll advertising, with the rest coming from sponsored posts. He has also just launched his own range of merchandise.


Influencer marketing is now very much part of the mainstream when it comes to marketing strategy. The size of the market is estimated to be $5bn globally, with 54% of this being spent on A-list celebrities. But how effective the strategy is remains up for debate. According to Zine, a company that works with both brands and influencers, companies are wasting over $2bn a year on “lacklustre” results. This is due to poor targeting, follower fraud (which has led to Unilever vowing to never work with influencers who purchase followers), and a disengaged audience. For example, only 0.3% of baby boomers claim to be influenced by influencers, with the majority of consumers saying they prefer influencers who produce authentic, engaging content.


What we are increasingly seeing is that size matters when it comes to influencer marketing, and not in the way you might think. Markerly, another influencer marketing platform, recently reported that micro-influencers, not those under the age of ten like young Ryan, but those with fewer than 1,000 followers, enjoyed the best ‘like’ rates and could be a more cost-effective solution for marketers. Nano-influencers are the next stage of this. These are typically social media users with a three-figure follower count that brands are beginning to value for their reach. The argument is you are more likely to act on something when it’s a personal connection advocating for it than you are if it’s a Kardashian or Rhianna.


For B2B brand strategy, I would argue that this isn’t news. B2B marketers have always known that quality over quantity always wins the day.

“It’s about reaching and influencing the decision makers,” suggests Brandigo’s China President, Mike Golden. “You could invest your marketing budget in one or two A-listers but if you’re a B2B brand and your objective is to generate sales, and the person who makes the purchasing decisions has no interest in the influencers you choose to partner with, then you have just wasted your time and money. But if you can find the influencer who has the ear of that person, even if they only have a handful of followers, your ROI is going to be much more positive.


“I think as B2B specialists our B2B marketing campaigns have always had to be more targeted and focused on the channels that can genuinely enhance our campaigns and offer value for our clients. Back in the days when traditional print media was king, a trade title with a low circulation but one that was read by senior decision makers was as much a valuable placement as a national newspaper mention was to a B2C campaign. The channels might have evolved and moved on but the theory remains the same. Taking China B2B marketing as an example, WeChat KOLs can make a big difference to the success of any campaign but they have to be well mapped and provided with content that is authentic and engaging for their followers for them to add real value. You can generate as many likes as you like, but if you aren’t influencing those with actual purchasing power then you have to ask yourself just how influential your influencers are.”

In this episode... Steven and Casey discuss: Why genuine connection can be more powerful than transactional B2B marketing How podcasts can build brand, create demand and strengthen customer relationships Why marketing technology and automation should never replace understanding your customer How AI is increasing content noise – and making human connection even more valuable Why global marketers need to keep challenging what they think they know about their customers Do you really know your customer? Technology gives marketers more opportunities than ever to automate, measure and optimise what they do. Casey experienced that transformation first-hand through marketing automation, gaining the ability to demonstrate how marketing activity contributed to leads, customers and revenue. But more technology doesn't automatically mean better marketing. Casey found that many companies were using only a fraction of the capabilities of the technology they had purchased. Worse, marketers could become so focused on platforms, features and automation that they lost sight of the person they were actually trying to reach. The same problem applies to content. Whether a 17-page report has been painstakingly written by an expensive expert or generated in seconds using AI, the fundamental question remains the same: What question does this answer for your buyer? From go to market to connect to market This becomes particularly important for global marketers. Pain and intent may be universal, but the people experiencing them – and the way they choose to solve their problems – can be very different across markets, cultures and generations. A buyer persona created ten years ago may bear little resemblance to the person making the same purchasing decision today. And a persona developed for one market can't simply be assumed to work everywhere else. Casey's answer is deceptively simple: keep talking to people. For him, this is another reason podcasting has become such a powerful marketing tool. It creates a consistent reason for marketers and business leaders to have meaningful conversations with the people they want to understand. It also sits behind his latest concept, Connect to Market . Rather than simply taking a product to a market, Casey argues that businesses should think more deliberately about how they connect with the people within it – through podcasts, communities, partnerships and other human-first approaches. As AI makes it easier to create more content, more quickly, those genuine human connections may become more important rather than less. Because amid all the automation, algorithms and AI-generated noise, great marketing still begins with understanding another person.
