Cookie 'cart_currency' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
Cookie 'localization' is missing the Secure flag

Page weighs 17.3 MB (10.1 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
11 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
2 control(s) without accessible label
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

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%.
- Page takes 25.6s to loadUsers abandon at ~3s — you're 23.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 2.5sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 4 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- HSTS is enabled but max-age is short (7889238s)First-visit protection is in place, but browsers forget the policy sooner than recommended→ Raise Strict-Transport-Security max-age to at least 31536000 (1 year)
- 2 form field(s) without a labelScreen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes→ Associate every input with a visible <label for="…">; add autocomplete attributes
