A WordPress website audit is a structured technical review of an existing WordPress site. It looks at the health of WordPress core, plugins and themes, the PHP and hosting environment underneath, and the security, backup and performance position around them.
It covers the parts of a site that quietly decide whether it stays fast, dependable and safe to update: update state, plugin quality, admin users and access, SSL and HTTPS, backups, error logs and whether the hosting still fits the site.
The aim is not to produce a long technical document nobody reads. The aim is to identify what needs attention, what is urgent, what can wait and what should be improved next.
