How healthy is your website?
A technical check of speed, Core Web Vitals, SEO, accessibility and security - with clear findings, concrete fixes and a PDF you can pass on to whoever looks after your site.
What we check
Performance
Lighthouse scores for mobile and desktop, and what slows the page down.
Core Web Vitals
Loading, responsiveness and layout stability against Google’s thresholds.
SEO
Titles, descriptions, headings, canonical, robots.txt, sitemap and structured data.
Accessibility
Image alt text, form labels, language, contrast and heading structure.
Security
HTTPS, mixed content and the HTTP headers browsers rely on.
Where the numbers come from
Real-user data
Where Google has it, how real Chrome visitors experienced the site over 28 days.
Lighthouse lab
A simulated mobile and desktop run through Google PageSpeed Insights.
Our own checks
We fetch the page and read its HTML, headers and crawl files directly.
Every number in the report says which of these it came from. The overall health score is Tetbit’s own composite, not a Google score.
Privacy
We only scan pages that are publicly reachable, the same way a search engine would. We store the scan and its result so the report link keeps working, and we keep a salted hash of your IP address to prevent abuse - not the address itself.
Running a scan does not sign you up for anything. We will not contact you for marketing unless you ask us to, using the form on your report.
