Security — nothing to patch
Plugin and CMS core vulnerabilities are one of the most common ways small business sites get compromised. A static HTML site with no plugin ecosystem has no plugin vulnerabilities to exploit in the first place.
Performance — fast by default
No database queries on every page load, no bloated theme framework, no unused plugin scripts loading in the background. That's a structural reason a static site consistently scores 90+ on Performance without special tuning.
Stability — nothing breaks on update
There's no plugin update that can suddenly break a payment gateway or a contact form, because there are no plugins to update. Changes only happen when we make them, deliberately.
