Missing Content-Security-Policy header

Missing meta description
SEOAdd a ~150-character meta description to control your search-result snippet and lift click-through rate.
No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
1 cookie without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
More than 20% of images are missing alt text
AccessibilityAdd alt attributes to the remaining images (use alt="" for purely decorative ones).
1 broken link on the page
SEOFix or remove broken links — they waste crawl budget and erode user trust.
