The best content management system is the one your team can use safely and consistently. Popularity matters less than fit: content types, permissions, integrations, editing habits, performance, and ownership all count.
Ask about the work
Who publishes? Do pages need approval? Will the site have products, resources, locations, or multilingual content? Which integrations are essential? How often will the structure change?
Think beyond the demo
Check export options, accessibility, hosting, updates, backups, user roles, and the cost of adding a small feature. A simple editor with a clear content model often beats a more powerful system that nobody wants to maintain.
These questions belong in website discovery before a platform is selected.
