"We build quality websites" is one of the emptiest phrases in this industry. Every shop says it. Every template vendor says it. Clients have no way to verify it at the point of purchase, which is exactly why everyone can safely say it.
Quality has to be measurable to mean anything. And for websites, it is. Google ships a free auditing tool called Lighthouse that scores any public site on four dimensions, each from 0 to 100. The tool runs in your browser, against any URL. You don't have to trust the developer. You can check the numbers yourself.
Here's what this site scores on desktop, and what each number actually means for your business.
None of those numbers are accidents. Each one maps to dozens of specific decisions made during the build. Here's what they cover.
Performance: 98
Performance measures how long a visitor waits before they can read, tap, or scroll. Lighthouse has two modes: desktop and mobile. The mobile audit simulates a mid-tier phone on a slow 4G connection — the real-world condition most of your customers are in when they pull up your site in a parking lot or on a job site. Desktop uses a faster connection and no device throttling. The scores shown above are desktop.
A site that scores 95 on desktop loads and becomes usable within a couple of seconds. A site that scores 60 makes your customer wait long enough to close the tab. That gap isn't cosmetic. Google has published data showing that every additional second of load time increases the chance a visitor leaves before seeing anything. The score predicts whether customers stay or go.
Accessibility: 100
Accessibility measures whether your site can be used by people with disabilities: blind users running screen readers, people navigating by keyboard instead of mouse, people with low vision who need high colour contrast, people with motor disabilities who can't tap small touch targets accurately.
A perfect score means every image has descriptive alt text, every form field has a label, every interactive element is reachable by keyboard, colour contrast ratios meet WCAG 2.1 AA, and the page reads correctly when announced by assistive technology.
There's a legal dimension in Ontario. The AODA requires most businesses to meet WCAG 2.0 Level AA on public-facing websites. There's also a business dimension that gets less attention: roughly one in five Canadians lives with a disability. A site that scores 60 on accessibility is quietly locking out 20% of its potential customers.
Best Practices: 100
Best Practices covers the things that don't fit neatly into the other three categories: HTTPS, no deprecated APIs, no known-vulnerable libraries, no browser console errors, no passive event listener violations. It's the "nothing measurably broken" score.
A 100 here doesn't mean the code is sophisticated. It means it's clean. Scoring below 100 means something specific is wrong, and Lighthouse will tell you exactly what.
SEO: 100
The Lighthouse SEO score isn't a ranking prediction. It's a checklist of the technical fundamentals Google needs to index a site properly: a title tag, a meta description, readable font sizes, crawlable links, valid hreflang tags on multilingual sites, a working robots.txt, no indexing blockers.
A site that scores 60 here isn't just ranking poorly. It's shipping with broken fundamentals that Google's crawler trips over before it even gets to the content. That's not an SEO problem. It's a build problem that should have been caught before launch.
Why this matters before you hire.
You can't evaluate code before you buy. You can evaluate scores. Ask any developer you're considering to run Lighthouse on a live site they've built recently and share the numbers. If they won't, that tells you something. If they do and the scores are in the 60s, that tells you something else.
This isn't a trick question. The tool is free, it's public, and it's built by Google. Every site has scores whether the developer ever measured them or not. The only question is whether they built toward them.
The short version.
"Built right" isn't a feeling. It's four numbers on a scorecard Google makes available to anyone. On desktop: 98, 100, 100, 100. That's the scorecard we hold ourselves to, and it's the standard worth asking any developer to hit before you sign anything.
