2 cookies without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
Title longer than 60 characters
SEOShorten the title to under 60 characters so search results don't truncate it.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
2 broken links on the page
SEOFix or remove broken links — they waste crawl budget and erode user trust.
