Top 10 B2B Marketing Services with Killer Case Studies

B2B buyers are typically 57% of the way toward a decision before engaging with your sales team.

Effective B2B marketing services help business owners develop a marketing strategy, attract visitors to their site, and craft digital experiences that convert visitors into qualified leads to fill your pipeline. However, with thousands of marketing services in the market, it can feel overwhelming to find the right solution for you.

The answer? Look for results. This article reviews ten marketing services that have a track record of delivering results for B2B businesses, with killer case studies to prove it. 

What to Look for in a B2B Marketing Service 

Hiring the right B2B marketing service can put your business on the fast track to explosive growth. On the other hand, choosing an underperforming agency can cost you months in terms of wasted budget and time. So it’s pretty important to choose a growth partner than can actually deliver for your business.
But how do tell which agency will waste your growth investment, and which will pay for themselves many times over? 

The key is to look for results. B2B marketing services that can deliver results are not afraid to back up their claims with real testimonials, case studies, and client reviews. Look for reviews from companies similar to yours, and be sure they have a least a few solid case studies from B2B companies. 

Marketing for B2B companies is not the same as selling low-ticket consumer offers. B2B marketers need to understand how business buyers think, and know how to set up your sales team with qualified, eager-to-buy prospects. It’s not enough to fill a database with “leads”: successful B2B marketing campaigns fill the sales pipeline with qualified buyers.

B2B marketing is not about selling a product: it’s about selling a meeting. The best B2B agencies understand that their job is to communicate the value of meeting with your sales team so that the right prospects raise their hands and are excited about the opportunity to meet with your salespeople.

It can take days to sort through the hundreds of self-proclaimed B2B marketing agencies. But you don’t have days, or even hours, which is why we’ve done the research for you. We evaluated dozens of marketing services, and scoured websites and review sites, to track down proven agencies that met two important criteria: 1.) They work with B2B companies 2.) They publish compelling case studies that prove they can actually deliver for B2B clients. From the extensive list that met these criteria, we chose the best 12 providers to review for this article. 

For each service, we will provide a brief synopsis of the business and share an excerpt from one of the awesome case studies showcased on their site. By the end, you’ll be ready to connect with the B2B marketing service that is best positioned to help you achieve your specific goals.
