WordPress is an open-source content management system used to build and manage websites, blogs, and complex digital experiences.
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
Example
A business uses WordPress to publish service pages and articles with reusable templates. Its editors can update content in the dashboard, while theme, plugin, hosting, and permission choices determine how that content is delivered and maintained.
