How good is your website, really?

Enter an address. In about thirty seconds you get a score out of 100, the three numbers Google uses to judge your site, and the fixes that would move them, in plain language. Runs on Google Lighthouse.

Public pages only. The analysis runs in Google's Lighthouse from your browser; we store nothing unless you choose to send us the report.

How it's scored

One number, four ingredients.

The Lucid Score weights Google's four Lighthouse categories by how much each one affects whether a visitor becomes a customer.

Performance35%

Load speed and responsiveness on a mid-range phone over 4G. The single biggest driver of conversion we can measure.

SEO25%

Whether search engines can crawl, read and understand the page: titles, descriptions, crawlability, mobile usability.

Accessibility20%

Contrast, labels, alt text, keyboard use. Good for everyone, and increasingly a legal requirement.

Best practices20%

HTTPS, console errors, deprecated features, image quality and other signs of a site that is looked after.

A90–100Fundamentals in place. Improve the offer, not the plumbing.
B75–89A few fixable issues. Worth a focused week.
C60–74Average. Visitors and Google are paying a tax.
D40–59Losing visitors before they see the offer.
F0–39Fix the basics before buying traffic.

Lighthouse lab scores vary a few points between runs; real-visitor Core Web Vitals are shown where Google has them. Design, brand and messaging can't be scored by a machine. For those, ask for a human review.
