Baseline
Capture representative pages, devices, metrics, requests and known functional constraints.
PageSpeed & Core Web Vitals
Make website performance measurable and maintainable.
I diagnose loading, responsiveness and layout-stability problems, implement prioritized fixes and compare repeat tests before and after the change.
What does PageSpeed optimization improve?
It reduces avoidable work in the loading and rendering path so important content appears sooner, interaction stays responsive and layout moves less.
- Responsive image formats and delivery
- Font loading and unused formats
- Render-blocking styles and scripts
- Third-party resource timing
- Largest Contentful Paint elements
- Interaction and long-task bottlenecks
- Layout-shift causes and dimensions
- Caching and compression behavior

How are improvements validated?
A baseline is recorded before implementation, then the same relevant tests are repeated after changes to distinguish improvement from assumption.
Improve
Prioritize high-impact asset, rendering, script, font, layout and server-delivery work.
Compare
Repeat tests, confirm functionality and document remaining field-data or platform limitations.
Common questions
Can you guarantee a score of 100?
No. Scores vary with testing conditions, platform limits and third-party resources. The goal is measurable improvement without breaking the experience.
Are lab tests the same as real-user data?
No. Lab tests help diagnose controlled runs, while field data reflects eligible real-user visits over time.
Does speed maintenance continue after launch?
It can. New media, scripts, fonts and platform changes can be reviewed against an agreed performance budget.
Need a before-and-after performance review?
Share the website URL, platform, important pages and any third-party tools that must remain.
