The WordPress Maintenance Checklist for Business-Critical Sites

Weekly checks

Weekly maintenance catches the issues most likely to affect customers quickly.

Confirm backups completed and can be restored.
Review uptime alerts and recent downtime patterns.
Apply safe updates after testing riskier plugins.
Test core customer paths: contact form, checkout, login, booking, or lead form.
Review security alerts and unusual admin activity.

Monthly checks

Monthly maintenance is where you reduce slow drift: performance decay, plugin clutter, broken links, and content issues.

Run a speed and Core Web Vitals review on key pages.
Audit plugins for overlap, abandoned tools, and performance impact.
Check analytics for traffic drops on money pages.
Review form delivery and transactional email health.
Update priority content that has become stale.

Quarterly checks

Quarterly maintenance is the site health review. It should answer one blunt question: if something broke tomorrow, could the business recover fast?

Review admin users, passwords, 2FA, and agency access.
Confirm hosting resources still match traffic and store demand.
Check PHP, database, and server versions before forced host changes.
Run a restore test on staging.
Review redirects, sitemap, schema, and index coverage.
