Why poor performance holds websites back
Slow user experiences
Heavy pages, inefficient code and unoptimised content create frustrating experiences across devices and connections.
Performance affects results
Slow and unstable experiences can reduce engagement, weaken search visibility and prevent users from converting.
Problems keep returning
Without the right foundations and monitoring, performance declines as new content, features and integrations are added.

FAQ
Common Questions
What is website performance optimisation?
Performance optimisation improves how quickly and reliably a website loads and responds. It can include changes to code, images, fonts, animations, third-party scripts, hosting, content structure and technical configuration.
Why does website performance matter?
A faster website creates a smoother experience for users and can support stronger engagement, conversion and search visibility. It is particularly important for visitors using mobile devices or slower connections.
What are Core Web Vitals?
Core Web Vitals are Google metrics that assess loading performance, responsiveness and visual stability. We use them alongside wider technical and user-experience data rather than treating them as the only measure of performance.
Can you optimise an existing website?
Yes. We can audit and improve an existing website or platform without requiring a complete redesign or rebuild. We prioritise changes according to their expected impact, complexity and cost.
Which platforms can you optimise?
We work across Webflow, headless content systems and custom-built websites and platforms. The available improvements will depend on the technology, hosting environment and level of access provided.
Will performance optimisation affect the design?
Usually, the existing visual direction can be retained. In some cases, we may recommend adjusting particularly heavy animations, media or interface patterns where they are having a disproportionate effect on performance.
Can you guarantee a particular performance score?
No single score can be guaranteed across every page, device and testing environment. We instead establish realistic targets and focus on measurable improvements to real user experience and business-critical journeys.
How long does performance optimisation take?
A focused audit and improvement phase may take two to four weeks. Larger websites, complex platforms or projects involving significant technical debt may require a longer programme of work.
Is performance optimisation a one-off project?
It can be, but performance can decline as content, scripts and functionality are added. We can provide ongoing monitoring and optimisation to maintain improvements over time.
How is this different from SEO?
Performance optimisation focuses on speed, stability and technical experience. SEO covers the broader work required to improve discoverability, including technical structure, content, authority and search intent. The two often support one another.
