Do you use Google Lighthouse?

Yes. We run the official Lighthouse engine, the same one Chrome DevTools and PageSpeed Insights use. The difference is we translate the report and prioritize actions by expected AEO visibility impact, not just speed.

Why do I get a different score from PageSpeed Insights?

Lighthouse scores vary between runs because they measure actual network performance. PageSpeed also uses CrUX data (Chrome User Experience) when available, while Website Grader runs a pure lab test. Both are valid; we recommend comparing three runs to filter out network noise.

Do I get an action plan?

Yes. Each failed check comes with (1) what the problem is, (2) why it affects performance/SEO/AEO, and (3) a concrete fix. Actions are ranked by expected impact so you can start with what gives the most.

Do I need to register?

No. You provide a URL and get the report in the browser. Rate limit of 5 runs per hour per IP to prevent abuse. No email, no credit card.

Can I use the tool on client websites?

Yes. Many agencies use Website Grader as a first-pass on new clients to show concrete improvement points during the sales meeting. For white-labeled reporting with the client's logo, the Agency plan (4,999 NOK/mo, ~$449) applies.

Website Grader

Get a complete health check of your website in 60 seconds. We run Google Lighthouse against your URL and translate the result into an action list. You see scores for performance, SEO, mobile-friendliness, security, and accessibility — plus concrete actions ranked by expected impact.

Data verified: May 2026

What the grader checks

Five categories based on Google Lighthouse: performance (Core Web Vitals: LCP, CLS, INP), SEO (meta tags, canonical URL, hreflang, robots), mobile-friendliness (viewport, touch targets, font size), security (HTTPS, mixed content, vulnerable libraries), and accessibility (contrast, ARIA, alt text, keyboard navigation).

When to use it

As a first-line diagnostic when something feels slow or you see drops in organic traffic. Also perfect before a relaunch — run the grader both before and after to verify the changes actually improved the metrics, not made them worse.

What you get

0–100 score per category with color-coded status (red/yellow/green). Each failed check comes with an explanation of why it is a problem and a concrete code-or-config fix. Mobile and desktop results are reported separately.

Access

Completely free without registration. Rate limit of 5 grader runs per hour per IP (performance checks are heavier than scans). For batch grading of multiple domains or historical tracking, the Freelancer plan (990 NOK/mo, ~$89) covers it.

How to run a Website Grader report

Three steps from URL to prioritized action list.

Enter website URL — Paste the full URL including https://. The tool runs Lighthouse against both mobile and desktop view.
Wait for the report — A complete analysis takes 30–60 seconds. You see scores for performance, SEO, mobile-friendliness, security, and accessibility in color-coded form.
Follow the action plan — Click into each category to see failed checks with explanation and fix. Start with the category with the lowest score, and within it, the check marked "High impact".
