A B2B corporate site is a company's website for explaining what it offers to other businesses. “B2B” means one business sells a product or service to another business, rather than mainly to individual shoppers.
The site might describe the service, show how a company uses it, answer common questions, and offer a way to contact the sales team. Business buyers may need more detail because a purchase can involve several people and decisions.
The clearest site focuses on the visitor's real questions. A long list of company slogans is not as helpful as showing who the service is for and how it can be used.
