What Is a Knowledge Base?

A knowledge base is a centralized repository that stores information and content about a particular subject or topic, typically a product. Companies produce this informational content to help customers and employees find answers without picking up the phone, waiting for an email response, or bugging someone around them.

A knowledge base can exist on its own as software, live on a website, or integrate into other systems such as a CRM or help desk ticketing system.

Customer Self-Support Knowledge Base vs. Internal Company Knowledge Base

As mentioned above, knowledge bases can serve both customers and employees.

  • A customer self-support knowledge base includes information, guides, and answers to help customers make better use of a product or service. They can also give prospective customers a deeper look into the kinds of problems a product or service solves. You can see these in action by viewing the best knowledge base examples.
  • An internal company knowledge base serves employees, not customers. These knowledge bases aren’t shared outside of the company and include information about company policies, guides explaining company software and processes, and anything else that helps employees do their job.

What Is Knowledge Base Software?

Knowledge base software is a specific type of knowledge management platform for storing and sharing self-serve information and can be cloud-based, self-hosted, or hosted by a third party. This category of software creates searchable, easy-to-update knowledge bases, and some include extra features such as FAQs, tutorials, and internal wiki page creation.

Conclusion: Avoid These Common Failure Points when Implementing Your Knowledge Base

According to Gartner, many self-service flaws trace back to three points of failure:

  • external search
  • site navigation
  • self-service capabilities

Make sure customers can easily find your knowledge base when they land on your website from an external search so they don’t tie up your customer support team with calls or tickets. A good rule of thumb is to place the link to your knowledge base in your top-level navigation.

In addition, your knowledge base needs to be genuinely self-serve — audit your content regularly to confirm it is comprehensive and includes every single step your customers need to resolve issues on their own.
