Top Priorities (5)
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
No H1 heading found
No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.
Soft 404: server returns HTTP 200 for non-existent pages
Soft 404s (HTTP 200 for missing pages) confuse Google — it indexes the 'not found' page as real content and ranks it.
Cross-Origin-Embedder-Policy header is missing
COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.
Cross-Origin-Opener-Policy header is missing
COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
£156 investment → £7,627/month returns + GBP 17,550,000 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
7 barrier(s) likely increasing bounce by ~31%.
- No viewport meta tagMobile browsers render at desktop width and shrink — text unreadable, tap targets miniature→ Add <meta name="viewport" content="width=device-width, initial-scale=1">
- Page loads in 3.3sEvery additional 100ms above 2.5s costs conversions — you're 762ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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, …)

How you compare
Where this site stands against peers running the same stack.
Top 10% of HSTS sites score 95+ on Infrastructure; you're at 80 — closing this gap is the highest-leverage improvement.
Top 10% of HTTP/3 sites score 97+ on Infrastructure; you're at 80 — closing this gap is the highest-leverage improvement.
Technology stack
HSTS
Stack Architecture
HTTP/3 All Detected Technologies (2)
HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web.
Observations (2)
No build tool detected
A framework (HSTS) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.
Minimal technology footprint
Only 2 technologies detected. This suggests a simple setup with minimal dependencies — excellent for performance and security.
