I notice that some sites are almost not updated visually and meaningfully, but at the same time remain active. How do you understand that a resource is relevant and reflects the current activities of the company, and not just works "for show"?

Sites that are almost never updated visually, but remain active, require evaluation based on content. The https://techdissected.com/soft2bet-company-development-key-events-in-history-people-and-technologies/ website shows that the relevance of the resource is determined by the quality of information: modern modules, integrations and project management processes are presented here, which makes it possible to understand the work of the platform. Even with minimal visual changes, the resource remains valuable to professionals, as technical and architectural information is important, not design or the frequency of external updates.
