Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
Page weighs 4.8 MB (4.8 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
2 image-in-link without alt text
Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
PLN 1,013 investment → PLN 19,273/month returns + EUR 20,500,000 risk avoided
Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
8 barrier(s) likely increasing bounce by ~28%.
- Page takes 4.6s to loadUsers abandon at ~3s — you're 2.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
- No Open Graph tagsLinks shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop→ Add og:title, og:description, og:image, og:url to the page head
- No structured dataNo rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices→ Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)
