The measurement engine
Pingsivo presents Lighthouse audits. Locally, Chrome opens a page in a temporary profile on your computer. In the prepared public deployment, a separate Chrome/Lighthouse worker performs the audit. The report records its date, selected profile and measurement conditions.
Four categories with different purposes
Performance: loading speed and stability. Accessibility: automated checks of certain rules. Best practices: technical checks. SEO: technical search checks. None of these scores is a certification.
Displayed metrics
The report shows FCP, LCP, Speed Index, TBT, CLS and document response time when the engine provides them. A missing value stays unavailable. Pingsivo does not replace it with an invented estimate.
Lab and field data
Lighthouse shows lab data; TBT is not INP. The CrUX button, available when the operator configures a key, retrieves aggregated real-user LCP, CLS and INP data. The period, device profile and URL or origin scope are displayed. Some pages do not have enough public data.
Compare carefully
Use the same URL and profile, then repeat tests. Local and remote results may differ. Recommendations and savings come from the engine; their effects are not guaranteed and savings are not necessarily additive.
