Top Influencer Agency in the UK

Influencer collaborations give brands unprecedented access to target audiences. Tapping into these engaged and niche communities builds trust and brings attention to your brand. However, finding influencers capable of delivering these benefits and agreeing contracts with them costs significant time and effort.

Influencer marketing agencies streamline the search process by quickly pinpointing suitable collaborations from their pool of influencers. In addition, some agencies provide comprehensive campaign assistance, from creating content to executing paid social media advertising.

While agencies increase the likelihood of delivering a profitable influencer marketing campaign, each offers a unique service and area of expertise. This article details the services of ten of the top influencer marketing agencies in the UK.

Key Takeaways:

  • What is the function of an influencer agency? An influencer agency primarily matches brands with influencers for partnerships. The agency’s team analyses a brand’s requirements against data about various influencers to ensure a successful collaboration. In addition, the agency can produce creative content and provide campaign guidance to help brands navigate the complexities of influencer marketing.
  • How does an influencer agency differ from an influencer platform? Unlike an agency, influencer platforms empower brands to discover influencers independently. They provide all the data, from engagement rates to credibility scores, that brands need to identify viable collaborations quickly in-house.  
  • What are the top influencer agencies in the UK? Now that influencer marketing is increasingly important for brands, influencer agencies proliferate. This article details ten leading UK agencies, including The Goat Agency, House of Marketers, and Socially Powerful.

What does an influencer marketing agency (IMA) do?

An influencer marketing agency (sometimes referred to as an "IMA") partners with brands to streamline their influencer marketing efforts. These agencies primarily focus on identifying social media creators for brand collaborations, working like an outsourced influencer marketing department.

An agency analyses a brand’s requirements and pinpoints potential partnerships with candidates within its influencer network. It may also headhunt new talent to match brands with the most suitable creators.

Beyond simple matchmaking, influencer marketing agencies may manage negotiations, oversee campaign execution, produce content, and track campaign performance.

Given the wide range of expertise across agencies, brands must choose one that aligns with their marketing objectives. For instance, some agencies specialise in engaging younger audiences via platforms like TikTok, whereas others offer more comprehensive services across diverse social media platforms.

What's the difference between an agency and an influencer platform?

An influencer agency offers tailored support akin to that of a traditional talent agency, providing hands-on assistance to brands navigating influencer partnerships. However, this personalised service has downsides, including higher costs and access to a more limited selection of influencers.

On the other hand, an influencer platform is a technological software as a service (SaaS) tool that helps brands discover and connect with influencers independently. These platforms provide a wealth of data about influencers, including analytics to assess their reach, credibility, engagement, and potential fit for specific campaigns.

What’s more, Influencer platforms utilise AI to suggest potential collaborations, mirroring the bespoke matchmaking service agencies offer. It can also empower brands with extensions that provide data about various influencers across all social media platforms.

Influencer marketing platforms aim to streamline the process of forming influencer partnerships while also providing tools for managing these relationships, benchmarking against competitors, and generating automated reports based on key performance indicators (KPIs).

Deciding whether an influencer agency or platform suits your brand's requirements depends on multiple considerations, including the scale of your campaign, your internal marketing capabilities, and your desired level of direct involvement in the influencer marketing process.

Agencies serve brands seeking a full-service approach with strategic guidance and tailored campaign execution. Alternatively, platforms empower brands by providing the insight they need to make self-driven choices about influencer collaborations. Typically, platforms are more cost-effective, allowing you to expand your campaigns as you grow and increasing the likelihood of a strong ROI.
