Google’s Core Web Vitals (CWV) are crucial for search rankings, measuring speed, interactivity, and stability. Failing to meet these can lower your rankings, making it harder for customers to find you. A slow website frustrates visitors, leading them to competitors. By enhancing performance, we’ll keep your audience engaged, encourage exploration, and boost your bottom line.

FAQs
What does a performance audit include?
A baseline report, page weight and request review, Core Web Vitals checks, and a prioritised list of fixes with expected impact.
Do you check Core Web Vitals?
Yes. I review LCP, INP, and CLS, plus the real causes behind them such as images, fonts, JavaScript, and layout shifts.
Can you speed up an existing site without a rebuild?
Often, yes. If the foundations are decent, targeted fixes can deliver large gains without changing the design.
What do you need access to?
A URL list, key user journeys, and analytics access if available. For staging or gated areas, I need test logins.
How long does performance work take?
It depends on the causes. Image and font work can be quick. Large JavaScript and platform constraints take longer.
Will speed improvements help SEO?
It helps where speed blocks good user experience. Performance supports rankings and conversions, but content and relevance still lead.
Do you provide before and after evidence?
Yes. You get baseline results and updated results after changes, so progress is clear and measurable.
What kind of fixes do you usually make?
Image optimisation, caching, reducing JavaScript, improving font loading, trimming third party scripts, and fixing layout instability.
