⚠️ Critical Issues (1)
-
46/100
Core Web Vitals
Slow server response (1062 ms) directly impacts LCP, 6 of 9 images lack width/height - major CLS risk, TTFB is 1062 ms - significantly above 200ms target
Recommendation: Add preload hints for critical resources (fonts, hero image, main CSS)
Your site loads slowly. Our hosting runs on fast NVMe drives with built-in CDN, HTTP/2, and Brotli compression — measurably faster.

Top 15Add alt text to all images for better SEO and accessibility
Add explicit width and height to all images to prevent Cumulative Layout Shift
Reduce server response time from 1062 ms - use caching, CDN, or optimize backend
Slow server response time
The server responds too slowly. This delays page display to the user.
Users may leave before the page loads. Google may lower ranking.
Optimize the server, use caching, consider CDN or better hosting.
Add Article/BlogPosting structured data - crucial for AI content understanding
Missing structured data
The page has no Schema.org markup that tells Google exactly what the content is (article, product, company, etc.).
You're not taking advantage of "rich snippets" - enhanced results with stars, prices, images.
Add appropriate Schema.org type (e.g., Article, Product, Organization) in JSON-LD format.
Add significantly more valuable content - Google prefers long, detailed articles
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.
Data transfer is 60-80% larger than it could be. Page loads much slower.
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.
Google lowers rankings for pages without HTTPS. Users don't trust pages without the "padlock" in the address bar.
Install an SSL certificate (many hosts offer free Let's Encrypt) and redirect traffic to https://.
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.
The page is more vulnerable to XSS, clickjacking, and other attacks.
Add headers: X-Content-Type-Options, X-Frame-Options, Content-Security-Policy.
Add X-Frame-Options: SAMEORIGIN header. This protects against clickjacking attacks where an attacker embeds your page in a hidden iframe
Missing security headers
The page doesn't send basic security headers that protect against attacks.
The page is more vulnerable to XSS, clickjacking, and other attacks.
Add headers: X-Content-Type-Options, X-Frame-Options, Content-Security-Policy.
Add X-Content-Type-Options: nosniff header. This prevents the browser from interpreting files as a different MIME type, which can lead to malicious code execution

The page is more vulnerable to XSS, clickjacking, and other attacks.
Add headers: X-Content-Type-Options, X-Frame-Options, Content-Security-Policy.
Add <meta property="og:image"> tag with an image at least 1200x630 pixels. Without it, Facebook shows a random or empty preview
Missing og:image
No image for social media. Shared links will be without graphics.
Posts without images get significantly fewer clicks and shares.
Add og:image with an image address minimum 1200x630 pixels.
Only 0 of 8 images use modern formats - convert JPG/PNG to WebP/AVIF
Old image formats
Images use older formats (JPG, PNG). Modern formats (WebP, AVIF) are 25-35% smaller.
Slower page loading due to larger files. Higher data usage for users.
Convert images to WebP or AVIF. You can use <picture> for compatibility.
No images use modern formats (WebP/AVIF) - conversion can save up to 30% in size
