Top Priorities (5)

Sorted by impact
Critical: 1

Page weighs 11.4 MB (9.1 MB transferred)

Informational: total page weight (uncompressed) and bytes actually transferred over the wire.

Performance › Page Weight Budget
Critical: 2

2 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.

Accessibility › Link & Button Quality
Critical: 3

2 image(s) missing alt attribute

Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.

Accessibility › Alt Text Quality
Critical: 4

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.

Accessibility › Alt Text Quality
Critical: 5

2 link(s) with no accessible text

Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.

Accessibility › Link & Button Quality
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 14.6s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Accessibility issues exclude users who rely on assistive technology — an estimated 15% of your potential audience. Addressing the critical issues below would have the most immediate impact on your conversion rate.
Your LCP is 14.6s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.
4 accessibility issues exclude users who rely on assistive technology.

  • Page takes 14.6s to load
    Users abandon at ~3s — you're 12.1s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • High main-thread blocking time
    Page is non-interactive for 312ms after first paint
    → Defer third-party scripts and split large bundles
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No structured data
    No 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, …)
  • 1 broken link(s) on the page
    Clicks land on 404s — trust drops and the session often ends
    → Fix or remove the broken destinations surfaced on the Content tab

Observations (2)

No build tool detected

A framework (Google Play app) 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.

Complex technology stack detected

13 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
