Website analyzer

What does the analyzer check?

• Security — HTTPS and certificate, HSTS, Content-Security-Policy, clickjacking protection, cookie flags, mixed content, security.txt, email authentication (SPF/DMARC) and CAA.
• SEO — status code, indexability, title and description, headings, canonical, language, hreflang, robots.txt, XML sitemap, structured data, image alt text and internal links.
• Speed — server response time, compression, HTTP/2 and HTTP/3, render-blocking files, page weight, image formats and sizes, lazy loading, caching and third-party scripts.
• Accessibility, mobile and social — form labels, button names, zoom, viewport, theme color, installability and Open Graph share previews.

Each check has a weight; the overall score combines Security 25%, SEO 25%, Speed 20%, Best practices 10%, Accessibility 10%, Social 5% and Mobile 5%. Serious problems — no HTTPS, a page that cannot be indexed, or an expired certificate — cap the score so it stays honest.
