Google PageSpeed Insights is a free tool from Google that analyses how quickly and efficiently a webpage loads.It measures website performance on both mobile devices and desktop computers and provides recommendations for improving speed, user experience, accessibility and technical performance.
A slow website can frustrate visitors, increase bounce rates and reduce the chances that users complete important actions such as contacting your business, making a purchase or submitting an enquiry.
Why Website Speed Matters
Visitors expect websites to load quickly.
If a website takes too long to display content, many users will leave before they even see what your business offers.

Visitors are more likely to:
- Read your content
