Four common knowledge base mistakes are letting content go out of date, letting the structure get messy, using it to sell, and neglecting its design. Each makes it harder for people to find what they need, and when they can't, they look elsewhere: your teams to other sources, your customers to your competitors. Maintaining a knowledge base matters as much as building it.
A knowledge base gives customers and prospective customers their answers after a simple search, and frees your support team from easy questions for the harder ones. But creating a knowledge base is only the start. 4 Roads has built some simple knowledge management solutions, and these are four mistakes to avoid.
Why must a knowledge base be kept up to date?
In Deloitte's European Workforce Survey of 2020, 25% of employees rated the value of the information they got from colleagues or a knowledge base below average, and 28% rated its accuracy below average. What you give your staff and tell your customers may be unhelpful, or even harming your success.
A knowledge base keeps working only if you keep it updated, and review its content regularly to check it is still current. If you don't, an internal knowledge base becomes redundant: teams look elsewhere for information, or make decisions on wrong information. Customers may lose trust in your brand, or turn to competitors for more up-to-date answers.
How does a knowledge base get messy?
As you add newer and different information, a knowledge base can become messy and hard to search. If you aren't deleting and updating content, searches may return conflicting answers. It may hold everything your teams and customers need, but if they can't find it, it might as well not be there.
A knowledge base should be built in categories, divided into subcategories, and so on, and it is easy to lose that system as it grows. As yours grows, keep the categories relevant and make all new content follow the same structure. If content drifts from the plan, people struggle to find what they need, and if it is hard work, they look somewhere else.
Should a knowledge base sell?
No. An excellent knowledge base leads to sales, but it should never sell. Some businesses, looking for more engagement on their websites, start to sell more directly through their knowledge base, and alienate their customers.
People use a knowledge base to help themselves: for answers about your products and services, or to solve a problem they already have. Content that sells rather than helps forgets what a knowledge base is for: somewhere customers turn when they need help.
Why does a knowledge base's design matter?
We take in content visually. However much information your knowledge base holds, people will browse it less if it isn't attractive and easy to read, and if the design is outdated, they may find the same information elsewhere.
Once your knowledge base is established, start turning its content into video and graphics: illustrated answers are easier to understand. If your product or service is complicated or technical, a video is exactly what customers will look for. Rather than leave them to find one on YouTube about replacing a part or fixing a problem, host it in your knowledge base. It saves them time, and improves how they see and trust your brand.
What do these mistakes cost?
They may seem small, but they add up. According to IDC, Fortune 500 companies lose around $31.5 billion a year by failing to share knowledge.
These mistakes are common across many businesses, and often happen without companies knowing. How 4 Roads builds intelligent self-service.
