Sites I've Built
Each row is a Google Lighthouse mobile audit. Scores range from 0 to 100, and Google uses these metrics as ranking signals.

What it measures
Scores come from Google Lighthouse, the same auditing tool Google uses to evaluate sites for search ranking. You can verify any score yourself using the tester above or at pagespeed.web.dev.
What Each Score Means
- Performance: Load speed, interactivity, visual stability
- Accessibility: WCAG compliance and screen reader support
- Best Practices: HTTPS, security, modern web APIs
- SEO: Crawlability, meta tags, structured data
Why It Matters
- Google uses these as ranking signals
- Faster sites convert more visitors
- Accessible sites reach more people
Performance scores can vary slightly between runs due to network conditions. The numbers above are rounded averages. Accessibility, Best Practices, and SEO are deterministic.
Why these scores matter for your business
Search ranking. Google has been clear since 2021 that Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift, and now Interaction to Next Paint) are ranking signals. Performance score rolls those three up. A site at 35 won't outrank a faster site that targets the same keywords, even if your content is better. For local searches like "plumber in Lakewood" or "best coffee in Denver" where competition is tight, slow mobile experiences get filtered out before content quality even matters.
Conversion rate. Google's research has been published repeatedly: bounce rate goes up 32% when a page goes from 1 to 3 seconds, 90% from 1 to 5 seconds, and 123% from 1 to 10 seconds. The math is brutal for slow sites. If your homepage takes 4 seconds to load, you're losing roughly half the visitors who would have converted on a fast site. That's not a minor rounding error. It's the difference between a site that pays for itself and a site that doesn't.
Accessibility reach. About 26% of US adults have a disability that affects how they use the web. Screen readers, keyboard navigation, color-contrast needs, and reduced-motion preferences are all real audiences. An accessibility score of 100 means your site works for them. A score of 70 means there's a chunk of your potential market who land on your page and bounce because something is broken for them. ADA compliance lawsuits against small businesses have doubled in the past five years and most settlements come out of pocket. Building it right from the start is cheaper than a lawsuit.
Trust signals. A slow, broken site implicitly tells visitors that you don't care about details. For service businesses where the site is your storefront, that's the wrong first impression. Customers don't think "this site is slow because their developer is bad", they think "this business is sloppy and I should check someone else." Performance is a proxy for professionalism.
Frequently asked
What's considered a good Lighthouse score?
90 or higher in each category is the green-zone Google considers fast. Most small business sites land between 40 and 60 on mobile performance because they're built on bloated platforms with too many third-party scripts. Anything under 50 is genuinely costing you customers. Sites I build target 95 or higher across the board.
Why mobile-only? Why throttled?
Google indexes the mobile version of your site first. They've been on mobile-first indexing since 2019, so your mobile score is the one that affects your ranking. The throttling simulates a real cellular connection because that's the experience most visitors actually have. A site that scores 99 on a wired desktop and 35 on a throttled phone is failing the audience that matters.
Do these scores actually affect my Google ranking?
Yes, indirectly. Google has confirmed Core Web Vitals (LCP, CLS, INP) are ranking signals, and the Performance score rolls those up. A site at 95 doesn't automatically rank higher than a site at 70, but a site at 35 will rank lower than it should because Google deprioritizes slow mobile experiences. SEO and Accessibility scores don't directly affect ranking but they correlate with the technical health Google cares about.
Why do scores fluctuate between runs?
Performance is the only category that varies. Network conditions, ad bid timing, and third-party scripts loading at different speeds all affect the result. Variance is usually 5 to 10 points either direction. Accessibility, Best Practices, and SEO are deterministic and don't change between runs.
What if my site is on Wix, Squarespace, or WordPress?
You can audit it the same way. Most platform sites land in the 40s on mobile performance because they include CSS, JavaScript, and tracking scripts you can't remove. You can sometimes squeeze 10 to 15 points out by removing apps and using lighter image sizes, but the platform ceiling is real. WordPress sites with caching and a lean theme can do better.
Can I improve my own score without rebuilding?
Sometimes. Compress your images, remove unused tracking scripts, and lazy-load anything below the fold. Those three alone usually buy you 10 to 20 points on Performance. Accessibility, SEO, and Best Practices are easier to fix without code changes if you can edit your CMS settings (alt text, meta descriptions, heading structure). For a structural rebuild, the diminishing returns kick in around 70.
How often should I re-test my scores?
Once a quarter is plenty for a stable site. After any change to your hosting, theme, or major plugins, run it again. If you're tracking active improvement work, weekly during the project, then monthly to catch regressions. The free hand-audit covers all of this on a one-off basis if you'd rather have someone else look.
