A written review of the website you already have, measured against Google's published requirements: whether every page can be indexed and the sitemap covers it, Core Web Vitals measured on real phones, structured data and Open Graph tags, titles and canonical tags, and accessibility problems ranked by severity.

The report tells you what to fix first and how many hours each fix takes. Nothing in it promises better rankings or more traffic. If you want me to make the fixes, the report is the scope and I quote from it.

$600, fixed, for one site.
