Detailed Breakdown

🖱️

Duolingo UX Score

62

Buttons with no accessible names are like doors with no handles.

Your accessibility score (82) masks critical sins: buttons have no accessible names (screen readers see nothing), you've disabled pinch-to-zoom with user-scalable=no (cruel to mobile users), and forced reflows are causing layout thrashing like a broken computer fan. You're also hiding content behind render-blocking requests, so users see a blank page while your JavaScript sorts itself out. Remove the user-scalable=no restriction immediately, add aria-labels to all interactive elements, and get those buttons shouting their names from the rooftops. Your CLS (0.0) is perfect, so at least people aren't getting whiplash mid-scroll.

🔍

Duolingo SEO Score

92

Your SEO is secretly perfect, even though everything else is on fire.

This is the one bright spot: proper viewport, favicon, solid og:tags with correct dimensions (1200x630), and a clean site structure. You nailed the technical SEO foundation. But—and this is a massive 'but'—your H1 is completely missing, you have zero internal links detected, and that truncated meta description is actively sabotaging your click-through rate. You're like a car with a perfect engine but the doors are welded shut. Keep the SEO foundation but actually finish your HTML content and add meaningful heading hierarchy.

✍️

Duolingo Copy Score

18

Your meta description got cut off mid-sentence like a conversation with someone who doesn't care.

The meta description reads 'Duolingo is the world' and just... stops. It's like describing a movie as 'This is a film.' Your word count shows 1 word on the entire page, which means either your content is completely hidden, dynamically loaded with zero fallback, or you're running the world's most minimalist homepage. The og:description also cuts off mid-thought ('It'). This isn't edgy minimalism—it's a sign your page content isn't rendering or indexable. Add real, complete copy and ensure it's in the HTML, not hidden behind JavaScript.

🎨

Duolingo Design Score

48

Your color contrast is playing hide-and-seek with readability—and winning.

The contrast ratio failures mean your foreground and background colors are basically whispering sweet nothings to each other while users squint. With zero headings detected (no H1, H2, H3), your page structure has the architectural integrity of a Jenga tower in an earthquake. You're forcing users to scroll through a wasteland of content with zero semantic hierarchy. Add proper heading structure, boost that contrast to WCAG AA minimum (4.5:1 for text), and stop making colorblind users play 'spot the text.'

Duolingo Performance Score

14

Your LCP is 15.4 seconds; users forget why they clicked by then.

A 15.4-second Largest Contentful Paint isn't a performance metric—it's a cry for help. Your FID (530ms) means buttons feel like they're running through molasses. PageSpeed gave you a 30/100, which translates to 'this website loads like a flip phone in 2002.' You've got render-blocking requests strangling your critical path, JavaScript executing like it's solving climate change, and image delivery optimized about as well as a potato router. Implement image lazy-loading, defer non-critical JavaScript, use a CDN, enable compression, and consider dumping 4 of those 10 external scripts. Your LCP should target sub-2.5 seconds.
