Conversion and website optimisation
How website speed affects engagement and conversion
Use performance evidence to locate slow pages and evaluate the impact of improvements.
Slow or unstable pages can interrupt a task, but analytics alone cannot diagnose the technical cause. Connect visitor outcomes with performance measurement and direct testing.
Find the pages and devices to investigate
Compare key outcomes and engagement clues by page and device, then check performance metrics from real-user monitoring or browser tools. Lab scores help reproduce conditions; field data describes a wider mix of networks and devices. Averages can hide slow experiences for a particular audience.

Prioritise pages on valuable paths such as product details, signup or checkout. Work with developers to identify large assets, render-blocking work, layout shifts or slow third-party code. Avoid adding a script for measurement without considering its own performance cost.
Validate speed and outcomes separately
After a release, verify that performance improved under comparable conditions and that event tracking still works. Watch progression and completed outcomes over a suitable period. A simultaneous campaign or seasonal shift can affect conversion, so avoid crediting every change to page speed alone.
