Utah Website Performance Benchmark
One Lighthouse score can tell you how a page behaved in one test. It does not tell you whether the site is typical for its industry, whether real users experience the same performance or which part of the page is creating the bottleneck.
How this guide is meant to be used
- Method
Baseline: Measure what is true today before changing anything.
The Utah Website Performance Benchmark is designed to compare real business websites across industries so owners and developers have a more useful point of reference.
What the Benchmark Measures
Core Web Vitals
LCP, INP and CLS using field data where available.
Page weight
Transferred bytes and the asset types contributing most to the page.
Network requests
Request volume and significant third-party dependencies.
JavaScript
Script weight and execution indicators where measured.
Images
Hero/image payload and responsive delivery patterns.
Technology
CMS, ecommerce platform, builder and major tooling where detection is reliable.
Why Industry Context Matters
A landscaping site may need a heavier image portfolio than a law firm. An ecommerce store may carry more third-party commerce functionality than a simple service site. A benchmark should show distributions by industry rather than claim one universal page-weight target fits every business.
Why Platform Comparisons Need Caution
WordPress, Shopify and modern JavaScript frameworks can all produce fast or slow sites. A platform comparison should include sample size, page type and implementation complexity instead of treating the CMS as the only cause.
How the Benchmark Helps Our Web Work
The completed study can inform performance budgets and development decisions across SEO Website Design, Shopify, WordPress and Lovable Development.
Is a perfect Lighthouse score required for SEO?
No. Performance matters, but the goal is a fast, stable, usable site with strong content and functionality, not sacrificing the business experience to chase a cosmetic score.
Can a photography-heavy site still be fast?
Yes, but responsive image sizing, modern formats, lazy loading and careful hero treatment become especially important.
