What changes when a website is slow
Speed is part of the experience: it affects access to content, especially on mobile and imperfect networks. Here we separate what can be measured from what can only be hypothesised.
QUESTIONS & ANSWERS
How much does a site's speed actually matter?
It matters because it comes before the content. Loading time, visual stability and interaction response can be measured with real data and tests across devices. No universal threshold guarantees conversion; the useful comparison is between pages, traffic and goals on the same website.
But my site works. Why should I worry?
Working means being available; being effective also means making the journey readable without avoidable waits. Commercial impact should not be assumed: compare drop-off, form completion and performance before and after the intervention.
What causes the slowness?
Common causes include unoptimised media, third-party scripts, fonts, unused code, caching and infrastructure. A serious diagnosis begins with measurements and a network waterfall, not a culprit chosen in advance.
How do you fix it?
We set performance budgets, optimise assets and test key pages on mobile. At launch, we document measurements and test conditions; third-party tools, future content and the user’s network remain variables to monitor.
How do I know whether the work helped?
Compare the same pages before and after: technical metrics, errors, journey completion and mobile behaviour. A technical improvement does not guarantee sales or rankings, but it removes an observable friction and makes the next experiment more reliable.
