How to fix

Add appropriate Schema.org type (e.g., Article, Product, Organization) in JSON-LD format.

CRITICAL: 46 broken internal links. Google treats this as a sign of low-quality site. Immediate action needed

7

Enable gzip or brotli compression for HTML, CSS, JS - reduces size by up to 70%

No resource compression

Server does not compress text files (HTML, CSS, JS) before sending.

Impact

Data transfer is 60-80% larger than it could be. Page loads much slower.

How to fix

Enable gzip or brotli compression in server configuration.

Add Strict-Transport-Security header with max-age of at least 31536000 (1 year). This protects users against HTTPS downgrade attacks

Page is not secure (no HTTPS)

Your page doesn't use encrypted HTTPS connection. Browsers show "Not Secure" warning next to the address.

Impact

Google lowers rankings for pages without HTTPS. Users don't trust pages without the "padlock" in the address bar.

How to fix

Install an SSL certificate (many hosts offer free Let's Encrypt) and redirect traffic to https://.

HIGH

Documentation
13

Add Content-Security-Policy header - the most effective protection against XSS attacks. Start with report-only mode: Content-Security-Policy-Report-Only

Missing security headers

The page doesn't send basic security headers that protect against attacks.

Impact

The page is more vulnerable to XSS, clickjacking, and other attacks.

How to fix

Add headers: X-Content-Type-Options, X-Frame-Options, Content-Security-Policy.

Text is very difficult to read (Flesch: 0, Grade: 12) - significantly simplify the language

HIGH

15

Images weigh 6.4 MB (54 files). Budget is 750 KB. Consider: WebP/AVIF compression, responsive images (srcset), lazy loading

Missing lazy loading for images

All images load immediately, even those not visible on screen. This slows down the page.

Impact

Slower first page display, especially on slow connections.

How to fix

Add loading="lazy" to images below the first screen.
