While HubSpot coined the term Content Optimization System (COS), the company announced at the 2017 INBOUND Conference that its platform is, in fact, a Content Management System. CMSs help companies manage websites and blogs.
The COS component of HubSpot software includes more marketing and sales functionality out of the box than other programs, including marketing tools to help manage analytics, social media, landing pages, and calls-to-action.
This makes HubSpot software basically a CMS on steroids. While these tools can be added to other CMS applications, they don’t always come standard like they do with HubSpot. It should be noted that in 2016, G2 Crowd named HubSpot its top CMS software, and was named No. 1 in both Market Presence and Customer Satisfaction with a total score of 87 out of 100.
