Missing security headers (score 0%)

Not set: Strict-Transport-Security, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options and 6 more.

Invalid canonical tag

Canonical points to the wrong URL — may cause duplicate pages in the index.

H1 heading missing

Every page should have exactly one H1 that describes its topic.

4 images without alt text

Alt text is required for screen readers and SEO — search engines cannot "see" images without it.

249 HTML validation errors

Invalid HTML can break rendering across browsers and hinder search engine parsing.

Title length: 82 chars (target 50–70)

Title too long — truncated in Google snippets.

Open Graph tags incomplete

Links shared on social media look bare — no image or description.

1 cookie without Secure/HttpOnly flags

Cookies without Secure are sent over HTTP; without HttpOnly they are accessible from JS — XSS risk.

Trailing slash inconsistency — /page and /page/ both accessible

Both URL variants return 200 without redirecting to each other — potential duplicate pages.

No Schema.org markup

Structured data helps get rich snippets in search results (ratings, breadcrumbs, etc.).

8 images without lazy loading

All images load immediately, even those below the fold.

Using GZIP but no Brotli

Brotli compresses 15–25% better than GZIP — supported by all modern browsers.
