- Speed
- Google’s own mobile speed test, plus server response time, page weight, compression, images and scripts.
- Findability (SEO)
- Everything Google reads first: title, description, headings, canonical address, language, robots.txt, sitemap, link previews and structured data.
- Mobile & accessibility
- Whether the page is built for phones, image descriptions for screen readers, the site icon and one-tap contact links.
- Security
- HTTPS, the redirect from http, and the security headers browsers use to protect visitors.
- Maintenance
- Signs of an unmaintained site: an old copyright year, outdated libraries, exposed software versions, missing statistics or cookie consent.
An automatic check reads the home page only and cannot judge design, texts or how well the site sells — that is what the personal review is for.
