The scanner normalizes the submitted address, discards paths, query parameters, and fragments, and checks the public homepage. It follows the permitted redirect chain to the final destination, observes the response, and runs separate browser assessments for mobile and desktop. Private, loopback, and otherwise disallowed network targets are blocked. This bounded approach makes the check useful without pretending that a public scanner has reviewed authenticated workflows, internal services, source code, business rules, or every route on the site.

That boundary changes how findings should be discussed. A missing header is evidence about the observed response. An accessibility failure is evidence from the tested rendered page. A detected library is a public signal, not proof of exploitability. An unavailable metric is not silently converted into a pass. For deeper assurance, teams still need manual accessibility review, authenticated functional testing, code review, dependency analysis, and—where appropriate—a properly authorized security assessment.

Begin with high-confidence failures that affect security, availability, indexability, or the ability to complete a primary action. Then look for clusters: several findings may share one root cause, such as a blocking script, an incomplete component pattern, or a header policy. Fixing the root can improve multiple categories at once. Conversely, do not let a large count of low-impact notices displace a single issue that exposes data, prevents keyboard use, or leaves an important page invisible to search engines.

Add product context that an automated scanner cannot know. Consider traffic, conversion paths, affected templates, release risk, engineering effort, and the cost of not acting. Define acceptance criteria before implementation: the observed header should appear, the affected control should receive a usable name, the layout shift should remain below the chosen threshold, or the duplicated description should become unique. Clear validation prevents “fixing the score” without fixing the underlying experience.
