Go to the website of many technology companies and find the link for case studies. The page that appears is likely a long, undifferentiated list of all the case studies the company has ever produced.
What a lost promotional opportunity!
Instead of taking time to look through the list, most customers will click on just the first one or two links. Or, they'll look for a company name they recognize, even if that case study isn't necessarily relevant to their interests or situation.
Two quick and easy projects can make your case studies much more appealing to customers and increase their marketing value for your company.
First, on the web page that lists your case studies, organize the title links by the categories most relevant to your customers, e.g. by industry, product, world region, etc. Simple subheads can be enough to segment the list, as shown by this example of a categorized case study list, used by my client MegaPath.
Another idea for this organizing project is to create a table that shows how the individual case studies fit into multiple categories.
The second project is to collect related case studies into a downloadable book. Again, the book can be organized by relevant categories in order to improve SEO and attract the attention of prospects as they browse through your site. A case study book can justify registration from prospects before the download and can serve as a "leave behind" printed document for your salespeople when they meet customers in person. One example, with case studies in summarized form, is provided by this customer reference booklet from SunGard UK.
Are there other ways that you have packaged case studies to increase their usage and impact?
