What a static site actually is
A plain-English explanation of static sites: files on a CDN, no PHP, no database, no server to maintain.

A static site is the simplest possible website: a folder of files, served to visitors from a global content delivery network. That is the whole setup.
The old way
Traditional sites run an application on a server. The server processes each request with PHP or similar, talks to a database and renders a page. That server is what needs updating, maintaining and paying for each month.
The static way
A static site is built once. The result is a folder of finished files. Those files are copied to a CDN, and visitors receive them from the nearest server. There is no application to process requests, no database to query, no server to patch.
The practical differences
- Speed. Files from a nearby CDN node are fast. Faster sites score better on the metrics Google weighs.
- Security. No PHP, database or plugins to update. Your domain, hosting logins and form services still need looking after.
- Cost. Free tiers on major CDNs cover typical business traffic.
- Maintenance. There is no server software or plugins to drift out of date, so most changes happen only when you make them.
What you keep
Forms, booking, search, comments and payments all work. They connect to services in the background. The visitor never notices the difference, except that everything is faster.
The trade-off
You lose the plugin marketplace and the server-side flexibility of a traditional stack. If your site is mostly pages, posts and forms, you lose very little.
I build static sites and migrate businesses onto them. If you want to know whether your site is a good fit, the audit is free.
