Several missing protections leave your users and data exposed.
Several issues make your site difficult for assistive technology users.
Solid SEO basics — a few optimizations could boost rankings.
Solid infrastructure — fast server responses across the board.
Mostly compliant — a few items need attention.
Rich content metadata — your pages look great everywhere.
Lean and efficient — low environmental impact per visit.
The overall score is a weighted average of individual category scores. Categories with more impact on user experience and security carry more weight.

Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Addressing the critical issues below would have the most immediate impact on your user trust.
7 barrier(s) likely increasing bounce by ~29%.
Page takes 6.2s to load
+12% bounceUsers abandon at ~3s — you're 3.7s over the 2.5s threshold
Fix: Optimize render-blocking resources, preload the hero image, and compress images
No HSTS header
+1% bounceReturning visitors are briefly exposed to downgrade attacks on first request
Fix: Set Strict-Transport-Security: max-age=31536000; includeSubDomains
No Content-Security-Policy header
+1% bounceHigher XSS blast radius — one compromised script can exfiltrate the checkout form
Fix: Ship a reporting-only CSP first, then enforce once violations are clean
8 form field(s) without a label
+6% bounceScreen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes
Fix: Associate every input with a visible <label for="…">; add autocomplete attributes
No structured data
+2% bounceNo rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices
Fix: Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)
Thin content
+3% bounceUnder 300 words — visitors bounce looking for substance, search engines rank competitors first
Fix: Add a substantive FAQ, product detail, or case-study section
No skip-to-content link
+1% bounceKeyboard and screen-reader users must tab through the entire header on every page
Fix: Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element

Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
Performance issues directly impact user engagement and conversion rates.
Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support older browsers. Learn why most sites can deploy ES6+ code without transpiling
Shipping ES5 transpiled code to modern browsers wastes bytes — every user with an evergreen browser pays for compatibility you don't need.
Most users today run browsers that natively support ES6+, async/await, optional chaining, and the rest of modern JavaScript. Transpiling to ES5 'just in case' adds 20-40% to your bundle for no benefit. Configure your build to target a modern browserslist, or ship a differential bundle pair (modern + legacy) with the module/nomodule pattern.

Multi-megabyte JavaScript bundles delay every interactive feature on the page.
This is the Lighthouse audit fired when too much JS is shipped relative to what executes. The fix isn't a config flag — it requires bundle analysis (webpack-bundle-analyzer, rollup-plugin-visualizer), splitting routes into chunks, lazy-loading off-screen components, and removing unused dependencies. Fundamentally different from minification: minifying reduces byte count, this reduces what's downloaded at all.
