Finding influencers for advertising: our guide

Advertising has a decades-old problem: consumers no longer trust it as they once did . The mental rejection of display ads, the rise of ad blockers, and the systematic skipping of television commercials are all symptoms of a deteriorating relationship between brands and the audiences they seek to reach. To address this, many brands are now turning to creators trusted by their audiences: influencers. But finding the right influencers for advertising is no easy feat. And the difference between a campaign that transforms this potential into real results and one that squanders it lies almost entirely in the rigor of the selection process. So, how do you find influencers for advertising? We'll tell you everything.

This article in brief

• Influencers can generate a significantly higher advertising ROI than traditional advertising with a soaring engagement rate.

• Selecting the right influencers is not based on the number of subscribers: the alignment of values and the actual engagement rate are the indicators that predict performance.

• Contacting relevant influencers directly is possible, but demanding: it requires rigorous prospecting, systematic personalization of approaches and a thorough knowledge of market practices.

• Delegating research and contact to a specialist agency like Clark Influence provides access to a network of qualified talent, proven analytical expertise, and integrated end-to-end management.

Influencers, one of the best pillars of modern advertising

Influencer advertising didn't emerge by chance. It addresses a problem that traditional advertising formats themselves created: by trying to be everywhere, by imposing themselves on attention spans uninvited, they gradually exhausted the patience of the audiences they sought to persuade. Today's consumer no longer simply endures advertising; they circumvent it, neutralize it, or ignore it with an efficiency that advertisers measure each year with growing concern.

Influencers operate on a completely different level. What a community maintains with a creator it has chosen to follow is a voluntary relationship , built over time, based on a form of trust that traditional advertising cannot buy. When this creator talks about a product or brand, they are not intruding on their audience's attention, but rather participating in a conversation that the audience has initiated.

This difference in approach explains why influencer advertising performs better than intrusive formats , and not just in terms of engagement. It performs better over time because a recommendation perceived as authentic sticks in people's minds differently than a mechanically repeated message. It also performs better in terms of conversion because the action of an audience that trusts its creator is qualitatively different from the distracted click of a user who has stumbled across a banner ad.

This shift from constrained to chosen advertising is a fundamental movement that is profoundly reshaping the advertising landscape and positioning influencers, when well-chosen and effectively activated, among the most powerful tools available to a brand. But be careful, we say well-chosen and effectively activated. Because the effectiveness of this tool doesn't stem from the channel itself, but from the quality with which it is used. A poor choice of influencer (even with an excellent product and a substantial budget) can produce complete indifference , or even backlash if the audience perceives a mismatch between the creator and the brand they are supposed to represent.

Therefore, finding the right influencers for advertising is essential. But how do you do that? That's the question Clark answers!

How to find the right influencers for advertising?

Criteria to observe

The first mistake brands make when searching for influencers for their advertising is starting with the most visible number: the number of followers. This is understandable, as it's the most readily available metric and the easiest to compare from one profile to another. But it's also the most misleading. In reality, audience size is no longer a reliable criterion for choosing an influencer. By 2026, successful brands will primarily look at audience alignment, the creator's reputation, the quality of interactions, and the ability to produce reusable content.

Four criteria have therefore become indispensable in any serious selection of influencers for advertising purposes.

Alignment of values comes first. A creator who talks about a brand whose world is consistent with their own creates a natural association that audiences immediately perceive. Conversely, an inconsistent placement can generate irony or mistrust rather than engagement.

The actual engagement rate is the second criterion. The focus is on the quality of the relationship between the creator and their community rather than simply mass visibility. Certain signals should raise red flags: sudden spikes in subscribers, inconsistent engagement, generic comments, a geographically disconnected audience, or an abnormal subscriber-to-interaction ratio. Interpreting these signals requires analytical expertise that few marketing teams possess without the necessary tools and experience.

The creator's consistent editorial approach over time is a third valuable indicator. An influencer who regularly changes their focus, accepts partnerships in vastly different sectors, or whose production quality is inconsistent sends signals of instability that brands should take seriously. Before collaborating, it is essential to analyze these signals.

The actual demographics of the audience are the fourth criterion. Millions of followers don't guarantee results if the audience doesn't match your target market. A lifestyle influencer with 800,000 followers, whose audience is primarily composed of 15-18 year olds, will be useless for selling a financial product aimed at 35-50 year olds. Demographic analysis should always precede any collaboration decision.

Contacting the pre-selected influencers effectively

Once the list of target creators is established—which already involves considerable research and analysis— comes the contact phase . And in reality, this is more delicate than it seems, for a simple reason: relevant influencers are in high demand. The most popular creators receive dozens of collaboration proposals every week. To stand out in this volume, a request must meet several conditions simultaneously: it must be personalized (reference to specific content, proof that the brand knows the creator), it must be clear about what it offers and the compensation provided, and it must be sent through the right channel.

Let Clark take care of everything!

Finding influencers for advertising is one of the most resource-intensive phases of any influencer strategy and one where mistakes are most costly. A sloppy selection process, a missed opportunity to connect with an ideal creator, or a poorly managed partnership can turn a promising investment into a waste of money.

At Clark Influence, we handle this entire process for our clients. Our Clark Talent Factory is specifically designed to meet this need: identifying the most relevant creators for each partner brand, verifying the impeccable quality of their audiences, and managing contact within established relationships that fundamentally change response and collaboration rates.

Our advantage lies first and foremost in our network . We have been working with creators on two continents for several years. These pre-existing relationships give us access to profiles that direct outreach could not reach under the same conditions, and to a knowledge of creators that goes far beyond what surface metrics reveal.

He also emphasizes our analytical method. We never select a creator based solely on their stated audience size. We analyze the quality of each profile using multiple criteria before proposing any profile to a client. This rigor is what transforms a list of influencers into a strategic asset.

Finally, it is important to our creative vision. Our Clark Content Lab produces the most engaging formats in accordance with the codes of each platform, ensuring that the advertising content created with our creative partners truly belongs to the culture of these platforms, not to the aesthetics of television commercials reformatted vertically.

Frequently Asked Questions

Why are influencers more effective than traditional advertising for certain objectives?

Traditional advertising relies on repetition and visibility to force memorization. Influence, on the other hand, is based on the pre-existing trust between a creator and their community. This trust transforms a recommendation into a reliable signal for the audience!

What type of influencer should you choose depending on your advertising objective?

It depends on what you're trying to achieve. To maximize reach and brand awareness, macro and mega-influencers offer unparalleled visibility. For conversion, industry credibility, or precise targeting objectives, nano and micro-influencers perform better thanks to their close community ties and significantly higher engagement rates. Most effective campaigns combine several influencer types depending on the stage of the funnel: larger profiles at the top of the funnel for visibility, and smaller profiles at the bottom for conversion.

Is the number of subscribers a good selection criterion?

No, and that's perhaps the most costly mistake a brand can make in influencer marketing. The number of followers says little about the true quality of the audience, its authenticity, its engagement, and its relevance to your target audience.

How does Clark Influence identify the right influencers for an advertising campaign?

Our Clark Talent Factory conducts a multi-criteria analysis for each campaign: alignment of values between the creator and the brand, audience quality and authenticity, actual engagement rate, editorial consistency, and partnership history. We never propose a profile based solely on its stated audience. This rigorous analysis, combined with our pre-existing relationships with creators in Europe and North America, allows us to identify profiles that direct prospecting would not reach.
