Beyond the score
Stays up during outages
Cached delivery serves the last good version if your origin fails.
Absorbs traffic peaks
The proxy cache serves ready pages, so spikes don’t topple the origin.
Lighter on your hosting
Fewer origin hits and less third-party code on the critical path.
Lower CO₂ per visit
A lighter page transfers fewer bytes and burns less energy.

*Core Web Vitals are a Google ranking signal, but work as a “tiebreaker” — they matter most when two pages are roughly equal in relevance and content. The biggest SEO benefit comes from moving out of the Poor zone (score < 50).

**Google / Deloitte (2019): 0.1 s improvement → +8% conversions in retail. Portent: each extra second of load time reduces conversion rate ~4%.

***Based on Google data: pages loading in 3 s vs 1 s show ~32% higher bounce rate. Estimate scales proportionally to LCP improvement and is site-specific.

What WebSpeed optimized
Next.js detected✓ Server headers tuned✓ Errors handled gracefully

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.
