There are many ways you can present a case study; it all depends on how you’d like to use the study. If you’d like to build credibility for your brand on your website, you can offer the case study as an ungated piece of content for anyone to view. If you’d like to offer a case study later on in the sales process and want to collect metrics on who views it, you can send Sales Qualified Leads (SQLs) a special link to view the case study (HubSpot is great for this!).
