A Practical Guide to Website Speed and Core Web Vitals
Slow websites lose customers and rankings. Here is a plain-English guide to making yours fast.
Speed is not a technical nicety. It is part of the experience. Visitors form an impression in the first second, and a sluggish page costs you sales before anyone reads a word.
Why speed matters
Faster sites convert better, rank better and cost less to run. Google measures real-world experience through Core Web Vitals, a small set of metrics that capture how quickly a page becomes useful and stable.
The three numbers to watch
- Largest Contentful Paint: how long the main content takes to appear. Aim for under 2.5 seconds.
- Interaction to Next Paint: how quickly the page responds to clicks and taps.
- Cumulative Layout Shift: how much the layout jumps around while loading.
Quick wins most sites can make
You do not need a rebuild to get faster. Compress and correctly size images, remove unused scripts, cache aggressively and serve assets from a content delivery network. These steps alone often cut load times in half.
A one-second improvement in load time can lift conversions more than a month of ad spend.
If you are not sure where your bottlenecks are, a short performance audit will tell you exactly what to fix first.
