PageSpeed scores are measured by Google PageSpeed Insights and are not guaranteed: they vary run to run and depend on network, device and third-party code.

FAQ
How do we measure?
We test each configuration of your site — the original and with our optimizations — 2–3 times for mobile and desktop, and take the median rather than a single run, which filters out random spikes.
Why does my PageSpeed show different numbers?
We use Google Lighthouse — the same engine behind PageSpeed Insights. Differences come from the test server location, CDN cache state and Lighthouse version. Compare columns with each other here: the relative improvement is what matters.
Does speed affect Google rankings?
Core Web Vitals are a ranking factor since May 2021, but Google calls them a tiebreaker. The clearest gain is moving out of the Poor zone (score < 50); if you are already Good, further speed still cuts bounce and lifts conversion.
