WordPress has risen to the #1 most popular CMS framework in the world by a long shot because content managers love its ease of use and developers love its flexibility.
WordPress empowers marketing teams with extensive content localization capabilities, including multilingual plugins, multisite instances, and custom field implementations.
Multisite architecture is a powerful feature built into the core of WordPress for spinning up many instances of your site while sharing the same theme, plugins, and code.
WordPress is one of the most SEO-friendly CMS platforms out there, so much so that the creators of WordPress have worked with Google on projects like core web vitals.
Not only can WordPress power your public-facing website, it can also power your internal knowledgebases and company portals, like an intranet or extranet.
