A business signs a deal with an influencer. Decent following, good engagement on the surface, content goes out on schedule, and the impressions look strong. And then nothing happens commercially. No meaningful spike in traffic, no uptick in enquiries, no sales that can be traced back to it. The influencer was professional, the content looked good, and the numbers in the report were impressive. The revenue just didn't follow.
The instinct is to conclude that influencer marketing doesn't work. Or that it only works for certain types of brands. Or that you need to spend significantly more before it does anything useful.
The honest answer is influencer marketing works, but only when the right questions are asked before the deal is signed. Most businesses are asking the wrong ones. Here's what to ask instead.
Influencer marketing has matured significantly. It's no longer a novelty channel or a tactic reserved for beauty brands and fitness supplements. It's a mainstream part of the marketing mix for businesses across eCommerce, hospitality, fitness, professional services and beyond. The commercial case for it, done properly, is strong.
A recommendation from a trusted voice in a niche community carries more weight than almost any paid ad format. People follow influencers because they trust their taste, their opinion, or their expertise. That trust is transferable. And when it's activated by the right brand, in the right way, it drives real commercial outcomes.
The problem is that most businesses are chasing the wrong version of it.
The default approach: find someone with a large following, pay for a post or a story, and measure success by how many people saw it. That approach consistently produces impressive-looking numbers and disappointing commercial results. The root cause is simple; follower count is a vanity metric. It tells you how many people have chosen to follow an account. It tells you nothing about how many of them are likely to buy from you, trust a recommendation, or even see the content in the first place.
The businesses getting genuine return from influencer marketing have moved past follower count entirely. They're asking different questions and getting very different results.
The instinct when approaching influencer marketing is to go as big as possible. A macro influencer, say 500,000 followers, strong brand recognition and more polished content, feels like the safe, credible choice. It also feels like it justifies the budget. If you're spending serious money, surely you want serious reach.
The reality is more complicated and more commercially interesting.
Macro influencers have large, broad audiences. But engagement rate (the percentage of followers who actually interact with content) drops significantly as follower count rises. A macro influencer with 500,000 followers might have an engagement rate of 1–2%. A micro influencer with 15,000 followers in a specific niche might have an engagement rate of 8–12%. That's not a marginal difference. It's a fundamentally different relationship between the influencer and their audience.
More importantly, the micro influencer's audience is there specifically because of their interest in a particular topic, product category, or lifestyle. That's not a broad audience that happens to include some potential customers, it's a concentrated audience of exactly the right people, who are actively engaged with content in that space.
The commercial implication is significant. A micro influencer post seen by 15,000 highly relevant people will almost always outperform a macro influencer post seen by 500,000 broadly relevant ones, in clicks, in conversions, and in cost per acquisition.
The budget implication is equally important. Macro influencers command significant fees, often five figures for a single post. Micro influencers are typically far more accessible, and the budget that would pay for one macro post could fund relationships with ten to fifteen micro influencers in the right niches. That's not just better value, it's a fundamentally different strategy. Broader reach across multiple relevant communities, more content, more touchpoints, and more data about what's actually resonating.
This doesn't mean macro influencers are never the right choice. For brand awareness at scale, launching into a new market, repositioning a brand, reaching an audience that doesn't yet know you exist, they have a role. But for most businesses asking whether influencer marketing can drive commercial results, micro is almost always the better starting point.
These are the six questions that separate businesses that get commercial return from influencer marketing from those that get a good-looking report and not much else.
Follower count tells you nothing about audience quality. Before signing anything, ask for an audience breakdown, like age, gender, location and interests. Does it match your customer profile? A men's fashion brand working with a lifestyle influencer whose audience is 70% female and based outside the UK is not going to see commercial return regardless of the follower count. The numbers might look right. The audience might not be.
Most influencers with a professional approach will provide this data readily. Those who can't or won't are a red flag worth taking seriously.
Engagement rate is more useful than follower count, but even engagement rate can be misleading. Look at the quality of the comments, not just the quantity. Generic comments like "great post", fire emojis, single-word responses, are often a sign of bought or incentivised engagement. They inflate the numbers without representing a genuinely engaged audience.
Real engagement looks like genuine responses, questions, and conversations. That's the audience that trusts the influencer's recommendations and the one that's likely to act on them.
This is the question most businesses forget to ask, and one of the most commercially important ones on this list.
If an influencer creates content for your brand, do you have the right to repurpose it? To use it in paid social ads? To put it on your website or in your email campaigns?
UGC-style content from influencers is some of the best-performing creative available for paid social. Authentic, unpolished, real; it stops the scroll in a way that studio photography often doesn't. But it's only available to you as a paid social asset if you own the rights to use it. Agreeing usage rights upfront, as part of the deal, can turn a single influencer post into a creative asset that runs for months across multiple channels.
Always agree usage rights before signing. Always.
Ask for case studies or examples of campaigns that drove measurable outcomes, not just reach and impressions. Has their content driven traffic? Conversions? Sales? Can they point to a brand they've worked with and show what happened commercially?
An influencer who can answer this question confidently, with specifics, is a very different proposition to one who talks about their audience size and their aesthetic. The former understands that they're a commercial channel. The latter is selling you a feeling.
The best influencer content doesn't look like an ad. It looks like the influencer's normal content because their audience trusts them precisely because they don't feel like a billboard. Over-briefing an influencer, insisting on specific scripts or heavily branded content, almost always produces content that underperforms. It looks forced because it is.
The brief should cover the key message, the product or service being featured, and any genuine non-negotiables. Beyond that, the influencer should have creative freedom. If you can't trust them to communicate your brand in their own voice, they're probably not the right partner and no amount of briefing will fix that.
A single influencer post is not a strategy. The businesses getting consistent return from influencer marketing treat it as part of a joined-up approach — influencer content feeds the paid social creative pipeline, drives traffic to pages that are built to convert, and supports a broader content strategy rather than sitting outside it as a one-off activity.
Before signing anything, ask yourself: what happens after the post goes out? Where does the traffic go? Is that page built to convert? How are you measuring what actually happened? If the answer to any of those is "we'll see", the campaign is unlikely to deliver what you're hoping for.
The difference between influencer marketing done properly and influencer marketing done hopefully is almost entirely in the preparation.
A well-structured influencer strategy starts with a clear brief that gives the influencer creative freedom within defined parameters. The audience data has been reviewed and matched against the customer profile before any deal is signed. Usage rights are agreed upfront so the content can be repurposed across paid social. The landing page or product page the influencer is driving traffic to is built to convert, not just the homepage with a vague hope that visitors will find their way.
There's a way of measuring what actually happened: UTM links, a unique discount code, or a dedicated landing page that makes attribution possible rather than guesswork. And the relationship is built over time rather than treated as a one-off transaction, because the influencers who drive the most consistent results are the ones who genuinely use and believe in the product. That takes time to establish, and it's worth establishing properly.
None of this is complicated. But it requires asking the right questions before the deal is done, not after the report comes in and the budget has been spent.
Influencer marketing works. The evidence across sectors is clear enough, brands of all sizes are generating real commercial return from it. But the gap between influencer marketing that drives revenue and influencer marketing that drives impressive-looking reports is almost entirely determined by what happens before the campaign starts.
The questions in this article are not complicated. But most businesses don't ask them, because they're dazzled by follower counts, rushed by an opportunity that feels time-sensitive, or simply don't know what good looks like until they've seen the alternative.
Slow down before you sign anything. Ask the right questions. Look at the audience, not just the numbers. Agree the usage rights. Make sure there's a plan for what happens after the post goes live.
And if the answers aren't satisfying, the budget is better spent elsewhere until they are.
