What is an influencer?
An influencer is a person who has built a loyal and engaged audience on social media by consistently creating content that their followers trust and feel inspired by. It can be anything from short videos on TikTok to personal stories on Instagram or longer blog posts on a website. The influencer uses their platform to influence the opinions, behaviour and often buying patterns of their audience. It's precisely this ability to influence that makes the influencer a valuable player in modern digital marketing.
You can think of an influencer as a bridge between brands and consumers. They don't act as traditional advertising billboards, but as people their audience actually listens to, because they build authenticity through ongoing engagement. The influencer's voice is personal, and it comes across as genuine rather than commercial. That creates a strong foundation for effective communication, especially on social media, where relationships and identification drive action.
How do you use your knowledge of influencers?
When you use an influencer in your marketing strategy, you reach a target audience through a voice they already trust. It's not just about getting a product mentioned, but about becoming part of a community where the message becomes a natural part of a personal story. You typically work with the influencer by developing relevant content that matches both your brand and the influencer's tone. That could be campaigns, social media collaborations, giveaways or product reviews.
Here, it's important to think holistically and bring in several marketing disciplines. For example, you can use SEO data to identify what the target audience is searching for and let that insight shape the influencer's content. In the same way, you can support the campaign with paid advertising (SEM or social ads), so your investment in influencer marketing becomes an integrated part of an overall digital strategy.
Why should you know about influencers?
Influencers play a central role because they influence both brand perception and buying behaviour among their audience. Credibility is the main reason influencer marketing has proven so effective. Consumers don't experience it as direct advertising, but as a recommendation from a person they feel they know. That's the difference between being seen as an advertiser and being perceived as a credible part of an existing conversation.
Influencer marketing is also cost-effective compared with traditional channels. Instead of broad, expensive exposure to an undefined audience, you get access to a clearly segmented community with documented engagement. This means you can measure concrete results in the form of click-through rates, conversions and brand awareness. It's also a method where you can work in a data-driven way and continuously optimise your investments, just as you would with Google Ads or social campaigns.
What types of influencers are there?
Influencers vary considerably in both size and specialisation. Some work with a few thousand followers, while others reach millions. That's why they're often divided into categories, which make it easier to choose a partner based on your goals:
- Nano-influencers: have up to around 10,000 followers. They're often strongly connected to their niche and have a close-knit community around their content.
- Mega-influencers: have over a million followers. They reach a broad audience and are often used for large-scale campaigns focused on reach.
In addition, there are micro- and macro-influencers, who sit between these two extremes. A micro-influencer might work within a very narrow niche such as sustainable living or tech gadgets, while a macro-influencer covers a broader field such as fashion or travel. Most social platforms have their own types of influencers, because the formats affect how audiences interact with the content. For example, short, aesthetic video content often works best on TikTok or Instagram Reels, while longer guides thrive on YouTube or blogs.
How do you use an influencer in practice?
The practical work with an influencer starts with defining your goals: do you want to build awareness, drive traffic or boost conversions? Then you choose profiles that match your target audience and your communication style. Once the partnership is in place, you develop content together with the influencer that feels authentic. This means leaving room for the influencer's own tone and storytelling style, as it's precisely that authenticity that makes the partnership valuable.
To assess whether the effort is working, you need to track exposure, engagement and actual actions — for example via campaign-specific links, landing pages or measurements in Google Analytics. The combination of creative collaborations and data-driven evaluation gives you the insight to optimise both future partnerships and your other marketing efforts. It's a good idea to compare results from influencer marketing with your other performance channels, such as Google Ads or social paid, to assess overall ROI.
What should you be aware of?
A successful partnership with an influencer requires transparency and a clear agreement. It's important to make sure the partnership complies with the applicable rules on advertising and the labelling of sponsored content. You also need to make sure the influencer shares your brand's values and has an audience that matches your strategic goals. Otherwise, you risk reaching an audience that doesn't feel ownership of the brand's message.
You should also consider the long-term perspective. A single post can generate immediate attention, but ongoing partnerships build a stronger and more natural brand presence. If you work strategically with branding, social media and content production, influencer marketing can become an integrated part of a coherent communication effort that strengthens both visibility and trust over time.
