All businesses purport the best tool to be in use, however, what are the real criteria when selecting a best knowledge base software? Such features as assisted search, mixed media (videos, docs, FAQs) hosting, user-friendly design that makes one think, at first, that he/she can find something, and integrations with customer support, team chat, or CRM tools. And also: knowledge and reporting, version control, multi-lingual support and scaling pricing. When you weigh them, you can better understand why some platforms come ahead in terms of usefulness, customer satisfaction and ROI.
