Influencer collaborations give you access to engaged audiences through voices those audiences already trust. The difference between a campaign that converts and one that wastes budget comes down to how well it's planned. This guide covers how to find the right influencers, agree terms, brief creators effectively and measure campaigns to ensure campaigns hit targets.

The definition of an influencer varies, but typically, a social media user becomes an influencer when they have 5k followers on a social media platform.
Influencers have proven understanding of their target market because their audience has chosen to follow them. Followers are, therefore, more likely to value and trust their content and be inspired by promotional content.
But running an influencer campaign isn't as simple as finding a creator with a large audience in your niche. You need to properly vet creators, set payments and define content expectations. If you are new to influencer marketing or haven't been in the industry long, you'll need a structured approach to make the right decisions.
Influencer collaborations should be planned. Brands need to understand where influencer campaigns fit in their marketing mix, pinpoint when content should be released and set clear goals.
Here's how an influencer collaboration works, step by step:
When you collaborate with influencers, you gain direct access to engaged, targeted audiences through voices they trust and choose to follow.
Here's why influencer collaborations are important and growing in popularity:
Brands can activate influencers in many different ways. Each type of campaign offers unique benefits, challenges, and fits within the marketing funnel.
A common entry point into influencer marketing is product gifting, which involves sending creators products in exchange for mentions in content. This brand awareness tactic generates authentic reviews and explanations that can make a product go viral at low costs.
The challenge is that many influencers receive more products than they can review, and without monetary compensation, they may not post about your product. It's also harder to control product and brand narratives. These issues may be why, according to Kolsquare's State of Influencer Marketing in Europe 2025, gifting campaigns are falling out of favour. They are now used by just 28% of marketers, who are currently shifting towards more structured, paid formats.
Sponsored posts, where brands pay influencers to create a specific piece of content, are a popular campaign type, with 61% of European marketers using them across all funnel stages. Brands benefit from the ability to plan and approve content in advance. That said, allowing influencers some creative freedom will keep content authentic.
Marketers and creators can co-create content to develop ideas that fit both their brands. This collaborative approach has become the most popular activation format in Europe, used by 64% of marketers. It is the leading mid-funnel format across nearly every market, reflecting a broader shift towards more hands-on content creation.
Ambassador programs are long-term collaborations that make the influencer a face for the brand. Around 38% of European marketers use ambassador programs, with the UK showing the highest adoption at 48%. Brands investing in this model are prioritising long-term credibility building over one-off visibility.
In affiliate models, the influencer promotes a product and earns a commission on sales generated, typically through a tracked link or unique discount code. Affiliate marketing, as a standalone strategy, is losing momentum: only 22% of marketers plan to increase affiliate spend in 2026, while 18% plan to cut it altogether.
User-generated content (UGC) is increasingly being repurposed and amplified through paid channels. This hybrid approach combines the authenticity of gifted campaigns with the targeting precision of paid media. It is used by 44% of European marketers and is growing fastest in the UK and Spain, where data-driven approaches are most advanced.
In-person and virtual events are used by 53% of European marketers, making them one of the more widely adopted formats. When running events, brands invite a group of creators to experience a destination or product launch together. It's particularly popular in beauty, cosmetics, and travel. Events work well for product launches and seasonal campaigns, where the shared experience generates a burst of simultaneous content across multiple creator channels.
Pricing in influencer marketing is not fixed. What a brand pays depends on a combination of factors.
The key factors that affect pricing are:
Across Europe, fixed fees per post remain the dominant compensation model, used by 74% of marketers according to Kolsquare's State of Influencer Marketing in Europe 2025. Long-term contracts are used by 31% of marketers and commission-based models by 28%.
Brands can use Kolsquare's Kolculator to get a data-driven starting point for budget planning on Instagram and TikTok. Across all platforms, we've run an analysis of budget per influencer.
Kolsquare's data provides a rough idea of how much brands spend per creator. The median annual influencer marketing budget across Europe is €175K, and the most common activation volume is 11–49 influencers per year. Taking the midpoint of that range (30 influencers) gives an approximate spend of €5,800 per influencer per year.
That figure should be treated as an estimate. It is also worth noting that the report does not specify what respondents included in their budget figure. But this suggests that most brands are not paying out huge sums for each piece of content.
That said, payments are rarely equal among creators. Most campaigns feature a mix of nano and micro-influencers alongside one or two higher-tier paid partnerships.
Brands seeking to understand how much to pay influencers can also use earned media value (EMV) as a guide. EMV estimates how much the reach and engagement from an influencer's post would have cost to generate using traditional marketing methods. Kolsquare's platform calculates EMV automatically for influencer content and allows you to track EMV for their past sponsored posts. This means you can assess the value of a potential partnership before you make an offer.
Let's look at how influencer costs vary by platform.
Instagram remains the most widely used platform for influencer marketing in Europe, with 93% of marketers running campaigns there. Rates vary significantly by tier. On the lower end, nano-influencers (1K–10K followers) typically charge between £10 and £100 per post. Micro-influencers (10K–50K followers) tend to cost between £100 and £500. Mid-tier creators (50K–500K followers) can command anywhere from £500 up to £5k, while macro and mega-influencers move into the $5K+ range with no real ceiling. Formats also affect pricing. A reel will typically cost more than a story from the same creator.
TikTok is the second-most popular platform, used by 79% of European marketers. Influencer pricing is less standardised than Instagram because rates are heavily influenced by virality potential and engagement rather than by follower count alone.
On the lower end, nano-influencers may charge around £50 per post, while micro-influencers can reach up to £1.5k. Mid-tier creators typically range up to £3k, while macro and mega-influencers can command £5k and above.
YouTube is used by 69% of European marketers and commands higher rates than most platforms because of the production effort required for video content. Pricing also depends on the format, with a dedicated video about a brand costing considerably more than a mid-roll mention or a brief integration.
Facebook's role in influencer marketing has declined in recent years, though it remains in use across Europe, particularly for reaching older demographics. Rates on the platform vary by tier, from around £25 per post for nano-influencers on the lower end, up to £25K or more for mega-influencer content. Micro-influencers typically fall in the £250–£1.2k range per post.
Here are some examples of these collaborations with UK influencers that had impressive results.
Lush's collaboration with Sanrio, the Japanese brand behind Hello Kitty, Pompompurin and Gudetama, proves that social-friendly products make campaigns more effective.
The collection featured shower jellies and bath bars shaped like Sanrio characters. The products were visual, tactile and novel. That combination gave nano-influencers the opportunity to create quick, genuinely interesting content for their audiences. Lush worked with a roster of nano-influencers, including Ellen Noir (@ellen.noir, 5.19K followers, Instagram), Edith (@with.edith, 7.63K followers, Instagram), and Sarah Jamieson (@sarahjamiesonmua, 3.21K followers, Instagram). These creators generated a combined reach of over 1.3M and EMV of €224.8K.
Each creator took a different approach. Ellen Noir filmed a close-up unboxing reaction, with the product centred. Edith shot a video showcasing the full range of characters. Sarah Jamieson produced clear explainer content showing how the products work.
All three posts carried clear #AD disclosure, and all three significantly outperformed what their follower counts would suggest. The results show that when the product is visually interesting and culturally relevant, nano-influencer content feels authentic and drives impact.
When Paramount needed to promote Scary Movie's UK cinema release, they didn't book a celebrity. They partnered with Bemi Orojuogun (@omo.oroje, 424K followers, TikTok), a micro-influencer known across London for her selfie-mode street videos featuring buses.
What makes Orojuogun a strong option for collaboration? Kolsquare's platform flagged her audience quality score at 94 out of 100, indicating a genuine following. She also has high engagement rates of 14% on TikTok and 11% on Instagram.
The two videos showed a Scary Movie-branded double-decker bus in London, packed with Ghostface actors doing the Wazzup. The first video also featured Scary Movie actor Marlon Wayans. Orojuogun filmed the content in her usual style, with the selfie camera, on the street, with her in frame and zero production polish.
The results were highly positive. The first video generated €1.2M EMV and 13.6M views on TikTok. On Instagram, it generated €5.82M EMV, 31M views, and 26M reach, and the overall campaign had a huge 2.6K% engagement rate.
The campaign is a perfect example of how local influencers and alignment with the influencer's typical content can generate strong engagement and reach.
Snack brand Proper partnered with Oladimeji Ajegbile (@hellodimeji, 446K followers on Instagram), an Edinburgh-based macro influencer whose signature content features him cycling with his son on the front of the bike.
Proper planned the content well by allowing Ajegbile to maintain his usual posting style. The sponsored content showed the father and son on a bike ride. When his son asks for snacks, Ajegbile reaches for a packet of Proper popcorn, which is clearly visible on screen. The son asks whether the popcorn tastes good, and his father says it does, but it's also high in fibre. Then his son asks what fibre is, and Ajegbile explains. The content feels like a natural, unscripted exchange, while also communicating the product's key message: that the popcorn tastes good and is good for you.
The post clearly showed #ad at the start to comply with regulations. It generated 533K likes, 2.8K comments and 7K shares. The reel resulted in over €690K EMV and 2.9M reach. Proper's own comment, "Officially our cutest fibremaxxer", received 14K likes, allowing the brand to foster more positive sentiment.
Again, the product fit the creator's style. Here, the brand engaged viewers with a story rather than centring the product, showing that adjusting your approach for the product and influencer works best.
Contacting an influencer to start a partnership can seem daunting, but with a structured and personalised approach, you can establish effective communication that leads to successful collaboration.
Here is a simple and straightforward methodology for engaging in dialogue and running an effective campaign.
Before reaching out, research the influencer carefully to confirm they are a good fit.
The right influencer will align on the following areas:
According to Kolsquare's Voices of the Creator Economy 2025 report, 47% of European creators rank shared values and ethical alignment as the top reason they choose brand partners. Ethics even rank ahead of compensation. This means that if you understand and share a creator's values, you can stand out.
When you write your first message, whether by email or DM, make it specific to the influencer. Don't send a generic, AI-generated message that feels impersonal. Instead, mention what you value about their work and explain clearly why you think a partnership would be mutually beneficial.
Be transparent about your offer, whether that is a free product, a flat fee, or a pay-by-commission arrangement. That way, influencers can quickly decide whether the collaboration suits them. You need to be realistic. Most influencers won't create a 20-second reel that shares specific brand messages for £50. According to Kolsquare's report, nearly three-quarters of creators report having experienced unrealistic demands from brands, and 71% say they have been offered deliverables that don't match the compensation. Setting clear, fair expectations from the start builds trust and avoids friction later.
An influencer brief should be concise but include all the information the creator needs to develop content. Most creators (64%) say they have been given unclear or constantly changing briefs during collaborations. Well-written briefs and influencer contracts help creators develop content that meets requirements the first time.
Invite the influencer to share their ideas on the collaboration and let them know you are open to their input. Creators know their audiences, and 66% cite excessive creative control or micromanagement as a recurring problem with brand partnerships. Treat the collaboration as a creative partnership that preserves the creator's unique voice and authenticity. After all, the creator has built their following through their content.
Brands must pay on time to build relationships with top influencers. 62% of creators say they have experienced late payments from brands. Detail your payment terms in the contract, and don't pay after the deadline. Many influencers rely on their social media income, and late payments can cause stress.
