Questions
Why is my result different from PageSpeed Insights?
PageSpeed Insights simulates a mid-range phone on a slow mobile connection. We load the page in desktop Chrome on a fast connection, so our times are usually quicker. Compare trends, not exact numbers.
Is one test enough?
Speed changes between visits and releases. Observability keeps testing so you can see the trend.
Does page speed affect SEO?
Yes. Core Web Vitals are part of how Google assesses page experience.
