While influencer marketing is closely connected to fleeting social media trends and viral posts, it’s a strategy that remains popular. In fact, according to Influencer Marketing Hub’s The State of Influencer Marketing 2024: Benchmark Report, since 2017 more than 80% of marketers held the belief that it’s an effective strategy.
The same report found that about a quarter of businesses turn to agencies to run their influencer marketing campaigns, while almost 60% use a third-party platform. If you’re one of the businesses that want to outsource marketing to an agency so that you can work with influencers at scale, here are 10 of the top influencer marketing agencies based in the UK.
Characteristics of a Top-Notch Influencer Marketing Agency
To find the best influencer marketing agency in the UK, let the following factors guide you:
Comprehensive Influencer Vetting Process: Great agencies work with carefully selected influencers who align with the brand’s voice, values, and target audience. The vetting process should look beyond follower counts to take into account engagement rates, audience demographics, content authenticity, and overall reputation.
Data-driven Campaign Management: Influencer marketing is no longer about guessing what works. It’s about data. The best agencies use advanced tools and analytics to track campaign performance, monitor social trends, and adjust strategies in real time. Every action should be backed by insights.
Commitment to Transparency: Your campaign’s success heavily depends on regular communication and clear reporting. You should be involved at every stage. Transparency keeps you in the loop and builds trust.
List of the Top Influencer Marketing Agencies in the UK
1. NinjaPromo
We don’t want to influence this list with subjective opinions about our own expertise. Like all influencer marketing strategies should be based on data, we also believe that you need to look at the data before you claim you’re a top-rated influencer marketing agency in the UK.
According to Clutch’s ranking system, we’re indeed the top micro influencer marketing agency based in London. They’ve also ranked us among the top 20 influencer marketing agencies in the UK. It might not be the top spot, but being named as one of the top 20 among nearly 9,000 companies is still a pretty big deal.
Speaking of deals, our flexible pricing is one of the features that have landed us a lot of praise. Whether you foresee only one to two regular influencer partnerships or need a full marketing department, we have a plan for you.
Another main benefit of working with us is that we’re a B2B influencer marketing agency. Influencer marketing isn’t traditionally associated with the B2B industry, but we have a network of key opinion leaders (KOLs) who specialize in B2B marketing. It’s one more way that we distinguish our influencer marketing services. Plus, unlike many other agencies that stick to audience analysis, we take it one step further to include a comprehensive social media platform analysis too.
