Your description is 334 characters. Keep it under 160 for best display.

Found 1 of 8 images without alt attributes. Alt text is critical for accessibility (screen readers) and SEO (image search).

1 of 8 images have no alt attribute. Screen readers cannot describe these images to visually impaired users.

Heading hierarchy jumps from H2 to H4. Don't skip heading levels — this confuses screen readers and assistive technology.

Some text appears to use light colors that may not have sufficient contrast against the background. WCAG requires a minimum 4.5:1 contrast ratio.

Your HTML is 282KB. Large HTML documents take longer to parse. Consider lazy loading content or splitting into multiple pages.

1 script without async or defer attributes. These block page rendering. Add defer or async to non-critical scripts.

8 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.
