- 02Core Web Vitals OptimizationTargeted work on loading (LCP), responsiveness (INP) and visual stability (CLS).
- 03Image and Media OptimizationServe media at the right size and format, and load it only when needed.
- 04Next.js Performance OptimizationUse Server Components, caching and bundling properly to reduce what reaches the browser.
- 05Technical SEO ImprovementsMake pages easy for search engines to crawl, understand and index.
- 06Website Performance AuditsA prioritized written report for teams who want to know what to fix before committing to the work.
- 07Mobile Performance OptimizationBuild for mid-range phones and variable networks, not just the developer's laptop.
Why speed matters
Fast means three things to a visitor
Does it load?
How long the main content takes to appear. A visitor who sees a blank page has no reason yet to stay.
Good: 2.5 s or less
Does it respond?
How quickly the page reacts to taps, clicks and typing. Slow feedback makes a working page feel broken.
Good: 200 ms or less
Does it stay still?
How much content jumps around during loading. Sudden shifts cause misreads and mistaken taps.
Good: 0.1 or less
Thresholds from Google's Web Vitals guidance.
Process
Test, change, and test again
- Step 1
Measure
Test key pages under fixed conditions and record a baseline before changing anything.
- Step 2
Diagnose
Trace each poor value to a specific request, element or task.
- Step 3
Prioritize
Rank fixes by likely effect and effort, so the biggest delays go first.
- Step 4
Implement
Make small, reviewable changes that keep accessibility and functionality intact.
- Step 5
Verify
Repeat the same test the same way, and report what actually changed.
Before and after
The same test, before and after the fixes
Largest Contentful Paint
LCP
When the largest visible element finishes rendering.
Total Blocking Time
TBT
How long long tasks block the main thread. The lab stand-in for responsiveness.
Cumulative Layout Shift
CLS
How much visible content moves unexpectedly while loading.
Featured case study
Making SpeedBoost's own site fast, and proving it
A self-initiated project: build a performance agency's website, add common real-world problems on purpose, record the damage with Lighthouse, then remove each problem and test again under the same conditions.
Self-initiated demonstration
This is not paid client work. The site tested is this one.

Straight answers
Is SpeedBoost a real agency?
No. SpeedBoost is a fictional agency created as a self-initiated portfolio project. The engineering and the measurements on this site are real, but there are no clients, staff or paid engagements behind it.
Are the performance results on this site real?
Every result is labelled. Figures marked as measured come from Lighthouse tests run on this website, and figures marked as sample are placeholders that were never measured.
Does a high Lighthouse score mean real users have a fast experience?
Not by itself. Lighthouse is a controlled lab test, which is ideal for diagnosing and comparing changes. Real experience also depends on visitors' devices and networks, so field data is the best check when a site has enough traffic.
Why does the report not show a measured INP value?
Interaction to Next Paint needs real interactions, which a standard page-load test does not perform. Total Blocking Time is reported as the lab stand-in, and INP stays marked as not measured rather than estimated.
Can better performance guarantee higher search rankings?
No. Page experience is one of many signals, and content relevance matters far more. Performance work removes obstacles and improves usability, but nobody can honestly promise a particular ranking.
What does the contact form do?
It is a working demonstration of validation and form states. No email service is connected, so messages are not stored or delivered, and the form tells you so after you submit it.
