Page speed is far more than a technical or aesthetic detail — it has a direct impact on your sales, conversions and overall growth. Studies show that a delay of just one second can cause a significant drop in conversions, making it clear that meticulous optimisation is essential.
Drawing on my own experience, I’ll explain how improving page speed can help you scale your business and outline the specific actions you can take to achieve it.
Why is it so important to optimise page speed for SEO and conversion?
Google officially treats page speed as a ranking factor. Amazon’s research revealed that every 100 ms of additional load time led to a 1 % fall in sales. Optimising page speed therefore boosts customer satisfaction, conversion rates and your ability to scale.
What tools are best for measuring page speed?
At Root we rely on three key tools to assess performance and uncover bottlenecks:
- Google PageSpeed Insights – shows how Google rates your site.
- Vercel Speed Insights – ideal for sites built with Next.js and hosted on Vercel.
- GTmetrix – provides detailed analysis and tailored recommendations.

How do we use image formats efficiently?
A cornerstone of our bespoke development is the correct use of modern formats such as .webp to replace heavier .png or .jpg files. Clients often upload images at unnecessarily high resolutions; to solve this we developed automatic resizing routines that adapt each asset to the user’s device via Sanity Studio.
