Website Performance Testing & Core Web Vitals Optimisation
Why website speed matters
Speed is essential for both users and search engines. Website performance testing helps identify issues that slow your site down and impact user experience.
A slow website can increase bounce rates, reduce conversions, and harm SEO rankings. Improving these metrics boosts usability, engagement, and your position in search results.
Performance is one of the four factors when we test core website vitals. 100 is the optimal score. All scores in an orange or red zone require improvement.
Core web vitals for Performance focus on five key metrics that influence your rankings and conversions:
First Contentful Paint (FCP)
First Contentful Paint marks the time at which the first text or image is painted.
Largest Contentful Paint (LCP)
Largest Contentful Paint marks the time at which the largest text or image is painted. It measures loading performance.
Total Blocking Time (TBT)
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Speed Index (SI)
Speed Index shows how quickly the contents of a page are visibly populated.

Our website performance testing & optimisation process
1.
Extensive Site Audit
We start with in-depth website performance testing to find speed bottlenecks, performance issues, and Core Web Vitals problems. This includes reviewing server response times, page load speeds, and mobile performance.
2.
Targeted Optimisation Strategies
Once we identify the issues, we implement customised solutions such as:
- Image compression and optimisation
- Minifying and deferring JavaScript and CSS
- Using browser caching and Content Delivery Networks (CDNs)
- Prioritising critical resources and enabling lazy loading
3.
Post-Optimisation Testing
After improvements are made, we run another website performance test to confirm speed gains and improved Core Web Vitals scores.
4.
Ongoing Monitoring and Maintenance
We offer continuous performance monitoring to ensure your site remains fast, stable, and compliant with evolving web standards.
