What is a PageSpeed Score?
Google PageSpeed Insights (PSI) measures how fast and well-optimised a webpage is. It runs in Google's Lighthouse engine and scores your site across four categories:
Performance
Measures how quickly your page loads for real users — First Contentful Paint (FCP), Largest Contentful Paint (LCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS). A score below 50 means visitors are likely leaving before the page finishes loading.
SEO
Checks that search engines can crawl and understand your page: proper meta tags, descriptive link text, valid robots.txt, and mobile-friendliness. A high SEO score doesn't guarantee rankings, but a low score will hurt them.
Accessibility
Evaluates how usable your site is for people with disabilities — colour contrast ratios, image alt text, keyboard navigation, and ARIA labels. Improving accessibility also tends to improve SEO.
Best Practices
Checks for modern web standards: HTTPS, no browser errors, secure cookie attributes, no deprecated APIs, and valid image aspect ratios. These are foundational quality signals.
Why Domain Age Matters
Google treats older domains as more trustworthy — they've had more time to accumulate backlinks and content. A brand-new domain (under 6 months) may rank more slowly even with excellent content. Our tool shows you the exact registration date pulled from RDAP (WHOIS replacement) records.
