A good knowledge base is easy to use, complete and kept up to date, easy for search engines to find, and fast. It puts what your people know within reach of your customers and your own teams, so they can find answers without waiting for someone to help. Plan all four before you build it, including a schedule for keeping it current.
Why does a knowledge base matter?
When you have an urgent question about how one of your products works, you ask the product manager. Your customers can't send them a Slack message or walk down the corridor to their desk.
What everyone in your company knows is one of its most valuable assets. A knowledge base saves your teams time, because they can get what they need without interrupting a colleague. For customers, it can change their whole experience of your brand.
Self-service has become a driving force of customer satisfaction. According to Zendesk's Customer Experience Trends Report 2020, 69% of customers want to solve issues on their own, and 63% search a company's online resources before contacting support.
What makes a knowledge base easy to use?
Design it around the people who will use it. If you need both an internal and an external knowledge base, you may need two designs built on similar knowledge. For both:
Make it easy to navigate. Your teams may be used to working a particular way; customers may expect something more general. Use categories and tags, and a search that finds information quickly.
Make it accessible. It should work on every device. That is often overlooked for an internal knowledge base, but your team isn't always at a computer in the office. Being inclusive of people with disabilities matters beyond the legal obligation: it widens your customer base and shows you are committed to helping.
Keep the interface simple. Icons, images and videos should support the content, and there should be as little as possible to learn. Customers need to find what they need without confusion, and without barriers like signing up, so they can solve their problem without relying on your support team.
How do you keep a knowledge base complete and up to date?
Your products, your services and what you know will keep changing, so plan from the start how you will keep up.
Cover everything. Include detailed step-by-step guides, FAQs, troubleshooting tips and best practice, for common, simple and niche issues alike. There is no such thing as a stupid question: the more of your customers' questions you answer, the more satisfied they are and the less they need direct support.
Update on a schedule. Businesses often update their knowledge base when they think it needs it. 4 Roads' advice is to plan a roadmap of updates before you build. Even when there is nothing new to add, review and revise what is there, so it keeps serving customers well.
Ask for feedback. Let people comment on the content, so you can keep improving it and cover new questions as they come up. An online community is one of the best ways to get genuine feedback, and linked to the knowledge base, it lets customers help each other alongside the answers you provide.
How do you make a knowledge base easy to find?
A knowledge base is as much a marketing tool as a support tool. People who haven't bought yet look for answers before they decide, and are more willing to buy if you guide them easily to the right ones. Treat it like your marketing content.
Use the words people search for. The more visible your knowledge base, the sooner people find what they need to buy or to solve their problem.
Link related articles. Link each search result to the articles related to it. One article may not answer the whole question, and pointing to others saves people searching again with different words.
Structure your data. Help search engines understand and categorise your content, so the knowledge base reaches people beyond the customers who arrive by a direct link.
Why does a knowledge base need to be fast?
A knowledge base can hold a lot of information, guides and video, and with that come loading and performance problems. Plan for it to load quickly: a high bounce rate can mean lost revenue, and more cost from the demand on your support staff.
What can its analytics tell you?
Look at your knowledge base's analytics separately from the rest of your site. They show where customers have problems, and what prospective customers want to know before they buy. Use them to improve the knowledge base and your products and services. If people keep asking about a feature, your marketing can reflect that, and convert more customers.
Customers and teams expect information at their fingertips. A knowledge base opens up help that would otherwise be locked away in scattered files, complicated databases and people's heads, so your customers can help themselves. How 4 Roads builds intelligent self-service.
