Page speed is part of the experience Google measures through Core Web Vitals, and it shapes whether visitors stay long enough to enquire or buy. A slow website can quietly cost you both rankings and revenue.
The good news is that most speed problems come from a short list of fixable causes.
What to measure
Use PageSpeed Insights and the Core Web Vitals report in Google Search Console to see how real visitors experience your pages. Look at loading time of the main content, responsiveness to taps and clicks, and visual stability while the page loads.
Common causes of slow pages
Oversized images, too many scripts and plugins, render-blocking files, slow hosting and missing caching are the usual culprits. Mobile connections magnify every one of these issues.
How to improve it
Compress and correctly size images, serve modern formats, defer non-essential scripts, enable caching and a content delivery network, and remove tools you no longer use. Re-test after each change so you know what worked.
