WordPress Site Health Checks

WordPress includes a Site Health tool (Tools menu) that runs diagnostic checks. The checks identify common issues; many sites have findings that warrant action.

The performance checks

PHP version. Older PHP versions get flagged; current versions don't.

Object cache. Persistent object cache is recommended for performance; missing it produces a notice.

Background updates. Whether the site can auto-update.

The security checks

Plugin and theme updates available. Outdated software flagged.

HTTPS status. Non-HTTPS sites get flagged.

File editing. Whether file editing through admin is enabled (security recommendation is to disable).

The recommended actions

The tool provides specific recommendations. Each check has a description and suggested fix.

Most recommendations are mechanical to implement.

The honest framing

Site Health is a free diagnostic that most operators don't use. The findings often reveal actionable issues.

For sites that haven't reviewed Site Health, the audit is worth doing. The improvements typically take 1-2 hours total.
