How to Succeed with Influencer Marketing

What is influencer marketing?

Influencer marketing is when businesses work with people who have built trust and influence on social media. When an influencer shares products, services, or messages they actually believe in, it feels more real than regular ads. That's why this type of marketing works so well – it's built on real relationships.

Simply put, you let someone who already talks to your audience share your message in their own way. This could be anyone from a local creator with a few thousand Instagram followers, to a YouTuber with hundreds of thousands of subscribers.

The term influencer marketing is used worldwide. It means working with people who have influence – people who affect other people.

A good influencer campaign isn't about buying attention, but about borrowing trust from someone who already has it.

Why influencer marketing works so well

Influencer marketing is not about following a trend, but about using a channel that delivers measurable results. People trust people, and the numbers show it. The figures below come from industry reports published in 2026, so use them as guidance.

• The global market was worth 32.55 billion dollars in 2025 and is expected to pass 40 billion in 2026 (Influencer Marketing Hub and Mordor Intelligence).
• 74% of marketers plan to increase their influencer budgets in 2026 (Aspire).
• Micro-influencers typically see 3 to 8% engagement, against 1 to 3% for large accounts (industry figures, 2026).

Industry figures show an average return of around 5.78 dollars per dollar invested. The number varies a lot between industries and campaigns, so always measure your own results.

The trend is clear: people want content that feels real, not staged. When a recommendation comes from someone you already follow, it feels more relevant than a regular ad. That is why credibility is the most valuable thing you build over time.

Influencer marketing has gone from an experiment to a fixed line in the marketing budget.

What influencers earn money from

• Sponsored posts and partnerships
• Affiliate links and discount codes
• Sales commission from their own online stores
• Events and brand ambassador deals
• Content creation for brands

Most influencers combine several of these income sources. Some live off steady partnerships with selected brands, while others get paid per view, click, or sale they create. Affiliate links and discount codes make it possible to track results directly, which gives both the business and the influencer a clear view of what works.

Many have also started building their own brands, like clothes, makeup, or digital products, and use their own channel as the main platform for sales. This way the influencer becomes both marketer and business owner.

What they all have in common is that income comes from trust. The more real and relevant the profile feels, the more valuable the partnership becomes.

How to succeed with influencer marketing

a) Set clear goals

Decide what you want to achieve: visibility, clicks, sales, or new followers. Pick 1–2 main goals and make them measurable. Examples: "+30% more trial orders from the campaign landing page" or "CPA under $15 from discount code." Also read our guide about marketing for service businesses to learn more about setting goals.

• Visibility: views (reach), view frequency
• Engagement: engagement rate (interactions divided by followers or views)
• Traffic: clicks, CTR, time on page
• Sales/leads: conversion rate, CPA/ROAS, number of code uses

b) Pick the right influencer

Look at values, audience, and engagement – not just follower count. The right match beats big reach every time.

• Audience match: age, gender, location, interests
• Engagement quality: comments and shares matter more than likes
• Content style: does the tone and format fit your brand?
• Trust: real history, steady quality, no bought followers

c) Let the influencer be creative

Give a clear brief with goals, message, and guidelines, but let the influencer tell the story their own way. Real and personal content works better than scripted ad copy.

• Share main message and "must-have" points (price, offer, deadline)
• Avoid word-for-word scripts. Ask for natural language and their own examples
• Agree on approval before publishing, and do one round of feedback

d) Combine channels

Use TikTok, Instagram, and YouTube together. Different formats build trust over time and reach your audience in different situations. Read more about how to measure digital marketing results.

• Short-form (Reels/TikTok/Shorts) for attention and pace
• Stories for closeness and direct response (swipe/link/DM)
• YouTube for deeper explanation and product demos
• Extend lifespan: reposting, cut into ads, create highlights

e) Measure results

Track what matters for your goal – and make tracking easy. Use a dedicated landing page, UTM parameters, and discount codes per influencer. Compare results and learn for the next round.

• UTM tracking on all links and separate campaign link per profile
• Discount code per influencer to tie sales to effort
• Look at both "early" signals (engagement) and "late" signals (sales/leads)
• Review 7–14 days after last post for a fairer picture

The recipe is simple: clear goals, right profile, real content, multiple channels, and consistent tracking. Do this every time, and results will improve with each campaign.

Micro and nano influencers – Small accounts, big results

Micro and nano influencers often work better than big accounts because their relationship with followers is closer. The audience knows the person, trusts their recommendations, and takes time to read, comment, and actually try what's recommended. For local businesses, this can be the difference between "visibility" and actual sales.

A nano influencer typically has between 1,000 and 10,000 followers. A micro influencer has between 10,000 and 100,000. The thresholds vary a little between sources, but the principle is the same: fewer followers means a closer relationship.

The shift is international. 54% of marketers now work mostly with nano and micro influencers (Aspire 2026).

• Trust first: Small accounts build relationships over time – recommendations feel like advice from a friend.
• Higher engagement: Fewer followers, but more real comments, shares, and saves.
• Relevance: Local audience and clear niches hit the target better.
• Better value: Lower cost per content and often lower CPA/CPM.
• Scalability: Multiple small accounts at once give broader coverage without losing trust.

A nano-influencer's followers know them personally – that creates extreme trust.

Example/case (illustrative): A small skincare brand in Oslo increased sales by 38% by working with ten micro-influencers instead of one big account. The result came from higher engagement, more unique discount codes, and content that felt more relevant to the audience.

AI-generated influencers and virtual profiles

AI-generated influencers are digital characters that act like real profiles on social media. A virtual profile has a name, a face and a personality, but the person does not exist. The content is made with artificial intelligence and 3D graphics.

Such profiles can work for brands that want full control of expression and message. A virtual character never gets sick, never says anything unfortunate and can be adapted to every campaign. For fashion, gaming and tech it can give a clear, recognisable style.

Markets grow fast here. Industry estimates put virtual influencer revenue above 15 billion dollars in 2026, and the format is strongest among young audiences. That makes the trend worth following, but it does not change our advice about trust.

Virtual profiles also have a clear weakness. They cannot try a product themselves, and they have no personal experience to share. Influencer marketing is built on the opposite: a real person recommending something they actually use. That trust is hard to create with a character.

Our advice is to use AI-generated profiles as a supplement, not a replacement. They can create attention around a launch, but few people buy because of a recommendation from someone who does not exist. Choose real profiles when the goal is trust and sales.

From 2 August 2026, the EU AI Act requires clear labelling of AI-generated or AI-manipulated content that looks real. Always label virtual profiles and AI content clearly.

Real case studies

Below are three short examples showing how different industries can succeed with influencer marketing. The numbers are illustrative, but the methods are practical and easy to test in your own business.

1. Local restaurant and TikTok creator

• Starting point: New weekend menu that needed quick attention in the local area.
• Action: Worked with a local TikTok creator who makes honest food reviews. Two videos, one restaurant visit, simple discount code in bio. (Read more about local SEO to reach customers in your area.)
• Result: 250,000 views in three days, 40% more reservations the same week, 27% of table bookings used the discount code.

2. Clothing brand and micro-influencers

• Starting point: Launch of capsule collection, limited budget.
• Action: Ten micro-influencers with 5,000 to 25,000 followers each. Natural Reels and Stories, unique tracking links and codes per profile.
• Result: Engagement tripled compared to earlier image posts, 34% lower CPA, steady sales over two weeks instead of one short spike.

3. Tech product and YouTube review

• Starting point: Product with multiple features that needs explanation.
• Action: Worked with a YouTuber who makes detailed reviews. One main video, clips to Shorts, link with UTM and coupon code.
• Result: 28% higher sales during the campaign, twice as long time on landing page, lower return rate because buyers knew what they were getting.

The recipe is simple: pick the right format for your message, use clear tracking per profile, measure both engagement and sales, learn and scale the next round.

Rules and responsibility, labeling and transparency

All paid partnerships must be clearly labeled. The goal is for people to quickly understand that the content is advertising, and who paid for it. Clear labels build more trust over time, and make it easier to measure real results.

The rules may also tighten. In April 2026, the Norwegian Consumer Council asked for a mandatory labelling scheme for influencer marketing, with special focus on protecting young audiences. Follow the guidance from the Norwegian Consumer Authority, which is kept up to date.

For AI content, new requirements arrived in 2026. The EU AI Act requires, from 2 August 2026, that AI-generated images, audio and video that look real are clearly labelled. Norway has not passed its own AI act yet, but it is expected during 2026. If you sell to customers in the EU, the EU requirements already apply.

Norway also has its own retouching rule. If you change the body\'s shape, size or skin in an ad, the ad must carry the Consumer Authority\'s standard label. The rule also applies when the change is made with AI. Our advice is simple: label all AI content now, regardless of deadlines.

• Always label: Use clear text like "Ad" or "Sponsored" at the start of the post, video, or title.
• Visible everywhere: Label both in the content itself and in the caption or description. In video, say it out loud and show it on screen.
• Who is the advertiser: State the brand you're working with, for example "Ad for Mementor".
• Gifts and discounts: Even gifts, discounts, or commission require labeling.
• Platform tools: Use "paid partnership" where the platform offers it, in addition to clear text.
• Children and vulnerable groups: Be extra careful with audiences under 18. Avoid products that don't fit them.
• Archive and editing: Don't remove labels in archived highlights or re-uploads. Labels should follow the content.
• Contracts and reporting: Set labeling requirements in the contract, and document that it's done right.

Clear labeling creates transparency, which leads to more trusted content, better response, and more consistent results over time.
