Use cases
When this check is worth running
Concrete moments where a health report should change what you do next.
Before a release
One pass over the areas most likely to regress between deploys, while there is still time to hold the release.
After a redesign
New markup and new assets move SEO, accessibility and performance together. This shows which of them moved.
Turning a backlog into a plan
Many small signals become one ordered list, ranked by the points each area actually costs.
Scope and limits
What this audit can and cannot see
The report separates what one page fetch can prove from what needs real user data.
Everything here comes from a single fetch of the page
The checks read the HTML, the response headers and a few same-origin files. They do not run your JavaScript, do not measure real visitors and do not keep a history of your site, so no trend or field metric is shown. A score is a summary of those checks, never a replacement for reading them.

FAQ
The questions that come up right after a report lands.
Does 100/100 mean the site is perfect?
No. The score summarises the checks this tool can run from one page fetch. It says nothing about content quality, business logic or anything that only shows up under real traffic. Read the findings, not just the number.
Does this replace Lighthouse or real user monitoring?
No, and it does not try to. Lighthouse renders the page in a browser and RUM measures real visitors. This check reads the delivered document and its headers, which is a different, complementary view: fast, needing no instrumentation, and good at configuration problems those tools skip.
Why do the charts stay empty until I run a check?
Because there is nothing truthful to draw yet. Every chart is built from your own result, so nothing is pre-filled with example values.
What does "points lost" in the priority matrix mean?
Each category carries a fixed weight in the overall score. Points lost is (100 minus the category score) divided by 100 and multiplied by that weight, so it is the exact number of overall points that area is costing you right now.
Website Performance and Core Web Vitals: Why They Matter for Business
Performance is not only a technical topic. Slow pages cost leads, harm SEO, and erode trust, and the things that fix them are usually small, specific, and boringly consistent.

Website Audit in 2026: The Complete SEO, Core Web Vitals, Accessibility and Security Checklist
A good website audit is not a single Lighthouse score or a list of several dozen automated warnings. It should answer four questions: can a search engine correctly discover and understand the website, can a user complete their task efficiently, is the website fast enough, and does it expose the owner or visitors to unnecessary risk?

A business website that doesn't generate leads isn't a marketing problem first, it's usually a structure problem. These are the decisions that separate a brochure from a website that works.
