Picture this: you’re a B2B company specializing in chemical disposal services. One of the biggest challenges B2B companies like yours face is a long sales cycle.
How do you get through to key decision-makers, establish a relationship, garner their trust, and get them to convert?
B2B influencer marketing can bridge this gap. A strong B2B influencer marketing agency can help you build relationships that deliver measurable outcomes.
This guide covers the best B2B influencer marketing agencies. It also provides insights on what B2B companies should look for when choosing the best agency for their business.
How Agencies Help Brands Collaborate with B2B Influencers
According to marketing executive Christopher Field, B2B influencers aren’t your regular influencers. They don’t have a huge following. What they have, though, is industry expertise and thought leadership. Field shares in a LinkedIn article that influencer marketing in the B2B field offers unique benefits:
“They command a different kind of influence: trusted voices in their domains, many times revered by your target audience. So, collaborating with them will not only extend your reach but also enhance your credibility, one of the key backbones of B2B marketing.”
B2B influencer marketing is changing the way businesses approach digital marketing. For instance, research from Ogilvy found that 75% of B2B marketers are already using influencers. According to the same research, 93% of CMOs are planning to increase their use of B2B influencers. When it comes to performance, 67% of B2B influencer campaigns outperformed brand-only marketing efforts.
B2B influencer marketing can be effective for building credibility and targeting niche audiences. However, B2B brands must carefully select influencers. They must prioritize those who align with their brand and industry and who can drive measurable results. But how do you know which influencers are the right fit for your business?
Agencies are crucial in identifying influencers, facilitating collaborations, and managing brand-influencer relationships. A good B2B influencer marketing agency can leverage its network to negotiate deals while ensuring that both parties benefit from the partnership. These agencies also provide strategic data-backed insights and creative inputs to maximize the impact and effectiveness of your campaigns.
Besides helping create content for brand promotion, these agencies provide additional services like video editing and campaign management. By handling these aspects, agencies enable brands to focus on their core business activities while delivering the benefits of B2B influencer marketing.
What to Look for When Choosing a B2B Influencer Marketing Agency
While agencies provide significant advantages, B2B companies must also consider challenges. For instance, the cost of hiring an agency can be substantial, not to mention influencer pricing varies wildly.
There’s also the brand ambassador vs. influencer dilemma. Which one best matches your brand, business goals, values, and requirements? Agencies can help you choose the best option using data to track brand partners with high potential.
Whether you’re working with a micro-influencer agency or planning to outsource marketing efforts to specialists, keep these points in mind.
- Check their network: How do they vet influencers? Assess their network and see if it includes B2B influencers who are experts in your niche.
- Evaluate how they measure influencer marketing success: What key metrics (engagement, leads, and conversions) do they use to measure influencer marketing metrics for campaigns?
- Industry fit and past performance: Look for agencies with prior experience working with other B2B companies in your niche.
