Performance baseline
Review available Core Web Vitals and other field data alongside repeatable lab tests. We select representative templates and define the device and network conditions relevant to the investigation.
Technical SEO
I help teams investigate loading performance, responsiveness, and layout stability across their important pages. The work combines available field data, lab testing, and an understanding of how the website is used. I work with developers to identify the implementation changes worth testing and validate the results after release.

These brands are part of my freelance SEO portfolio.















The work behind the service
A performance report is a starting point. Your team still needs to understand which resources or interactions create a problem and which users are affected. I review representative page types, devices, and target markets, then work through the relevant browser behaviour with the developers who can change it.
Scope and deliverables
We agree on the scope after reviewing your requirements. A project can focus on one of these areas or combine the relevant work.
Review available Core Web Vitals and other field data alongside repeatable lab tests. We select representative templates and define the device and network conditions relevant to the investigation.
Examine image delivery, styles, scripts, and important rendering dependencies. The goal is to identify concrete implementation work rather than pass on an unprioritised list of tool suggestions.
Investigate responsiveness and unexpected movement on the relevant pages. This can include JavaScript work, component behaviour, font loading, and other page-specific causes worth testing.
Prepare requirements, review proposed fixes, and compare the available measurements after implementation. Field data and lab tests are reviewed in their own context.
Working together
We agree on the templates, devices, and user journeys to investigate.
I use browser tools and the available data to identify practical changes with your team.
We retest the implementation and review subsequent field data where it is available.
Experience and related work
My freelance portfolio documents performance work on a JavaScript website with millions of visits, including collaboration with frontend and infrastructure teams and analysis by country and device.
Before we start
Yes. We can investigate the relevant rendering and resource-loading behaviour with your frontend team. The exact scope depends on the application and the pages affected.
No. The work focuses on diagnosing issues, implementing agreed changes, and measuring their effects. Results depend on the website, its dependencies, and the conditions being measured.
We agree on responsibilities at the start. I can investigate, prepare requirements, review code examples, and validate changes while your developers manage the application implementation.
Page speed and Core Web Vitals consulting
Send representative URLs, the devices or markets affected, and any performance reports or recent changes your team has already investigated.
