Yes, 100% free with no hidden charges, no account required, and no usage limits. You can analyze as many websites as you need — for any domain, any location, and any device type — completely free, forever. No credit card or signup is ever required to use the tool.

The overall score (0–100) is a weighted aggregate of your four category scores: Performance, Accessibility, Best Practices, and SEO. A score of 90–100 is excellent. A score of 50–89 indicates good performance with room to improve. Below 50 signals significant issues that are likely hurting your search rankings and user experience. Use it as a baseline benchmark — track changes after implementing optimizations to verify improvement.

Performance measures how fast your site loads using Core Web Vitals metrics like LCP, FCP, and CLS. Accessibility checks whether all users — including those with disabilities using screen readers — can use your site effectively. Best Practices evaluates technical hygiene: HTTPS, security headers, modern image formats, and absence of browser errors. SEO checks the on-page signals search engines use: meta tags, structured data, mobile-friendliness, and internal linking. All four categories are official components of Google's Lighthouse scoring system.

A speed test focuses exclusively on load-time metrics — how fast pages load, TTFB, Core Web Vitals. A Website Analyzer is broader: it includes speed as one of four categories but also audits accessibility (are images labeled, is contrast sufficient), best practices (is the site using HTTPS, modern formats, secure headers), and on-page SEO (are title tags, meta descriptions, and structured data present and correct). If you need to debug a slow site, use the Speed Test. If you want a full health check, use the Website Analyzer.

Yes, completely safe and legal. The analyzer only evaluates publicly visible signals — the same information any web browser or search engine crawler accesses when visiting a site. No login credentials are required, no private data is accessed, and the target site is not modified in any way. Analyzing competitor websites is standard SEO practice and perfectly legitimate.

Mobile analysis applies slower network throttling (simulating a 4G connection) and a lower-powered device profile, reflecting real mobile browsing conditions. Mobile scores are almost always lower than desktop. This matters because Google uses mobile-first indexing — it crawls and ranks the mobile version of your site primarily, so a poor mobile score has direct consequences for your rankings even if your desktop score is high. Always optimize for mobile as the primary target.

The highest-impact fixes typically are: (1) Compress and properly size images — unoptimized images are the single most common cause of poor performance scores. (2) Add missing meta descriptions and title tags — directly improves the SEO category. (3) Enable HTTPS if not already active — affects both Best Practices and SEO scores. (4) Add alt text to all images — major accessibility win. (5) Implement security headers (CSP, X-Frame-Options) — improves Best Practices. (6) Add structured data markup — boosts SEO category and enables rich snippets in search results.

No. The analyzer reads publicly available information about your website in the same way a search engine crawler would. It does not send large volumes of requests, does not modify any files, and does not interact with your server beyond a standard page visit. Your website's performance and availability for real users is completely unaffected by running the analysis. It is safe to run on live production websites at any time.
