OUR EXPERTISE
Here’s What We Learned About UX, SEO, and Speed
Specto Design’s 2025 audit reveals surprising gaps in Core Web Vitals, accessibility, and performance across the world’s most popular websites.
Why We Did This Audit
At Specto Design, we believe great digital experiences are built on data, not assumptions. That’s why we analyzed the top 1,000 websites in the world across industries—from news and ecommerce to education and SaaS—to evaluate how well they perform on the fundamentals:
- Mobile Page Speed
- Mobile Experience
- Desktop Page Speed
- Core Web Vitals
The result is a comprehensive dataset, free and open to the public, designed to help marketers, developers, UX teams, and business owners benchmark their digital presence against global leaders.
What’s in the Dataset?
Each site in the list includes:
- Industry classification (e.g., Media, Retail, Finance)
- Page load time (in seconds)
- Pass/fail on Core Web Vitals
- Mobile-friendliness rating
- Whether Lighthouse was successfully run
5 Key Takeaways
- Only 34% passed Core Web Vitals.
Despite traffic volume, performance optimization remains a gap. - Design quality doesn’t always follow popularity.
Some of the highest-traffic sites had low design cohesion or accessibility issues. - Accessibility is overlooked.
Over 40% of sites scored below 70% in our accessibility review. - Mobile-friendliness is the norm—but often superficial.
Many sites passed Google’s mobile test, but still had major layout shifts or slow tap interactions. - Industry matters.
SaaS and ecommerce sites generally outperformed government and media domains in speed and UX.
