Style of Support
How do customers try to reach you? Do they prefer email and support portal or social media? Do you want a minimal self-service portal that hosts only answers to your frequently asked questions or do you want a fully customizable solution capable of hosting videos and other guides? Choose the style of self-service you want to provide to your customers.
Usability
User experience is an important aspect of a good cloud-powered knowledge base software. For instance, Freshdesk’s knowledge base has a user-friendly interface that helps agents publish tutorials and articles with little to no effort. Alternatively, you can use an on-premise or an open source knowledge base software, but that means you will also be responsible for maintenance, site performance, uptimes, and so on. Check what you need and choose the right knowledge base system accordingly.
Price
See what others in your field are using, compare features and then decide which knowledge base software will help you deliver a good self-service experience. As with most other software, higher prices do not automatically mean a better knowledge base and a complicated UI does not necessarily imply feature-rich.
