Your description is 192 characters. Keep it under 160 for best display.

Heading hierarchy jumps from H2 to H6. Don't skip heading levels — this confuses screen readers and assistive technology.

Server responded in 1.0s. Aim for under 200ms TTFB. Consider caching, CDN, or server-side optimizations.

Your HTML is 303KB. Large HTML documents take longer to parse. Consider lazy loading content or splitting into multiple pages.

Loading 37 CSS files. Each blocks rendering. Consider combining stylesheets or inlining critical CSS.

10 images don't use loading="lazy". Add lazy loading to below-the-fold images to improve initial page load.

Add more internal links to help search engines discover and index your other pages. Internal linking also helps distribute page authority.
