You can and should monitor the traffic to the B2B case study(ies) posted on your website and to any B2B case study blog posts as well as social media such as Twitter, Facebook and LinkedIn.
You can also assess whether the case study feeds the sales funnel with specific calls to action connected to individual B2B case studies.
Of course, your sales and marketing team will also affect the ROI on the case study. Are they using it as handouts, at trade shows, in seminars, do they reference it on sales calls and in conversations? Do they direct prospects to the case studies on the website? Do they mention them in their social media posts?
If the B2B case study sits in a drawer or a computer file, it won’t increase your visibility, credibility or revenues.
