Website Speed and Core Web Vitals, Explained Simply
By Website in Gurgaon · · 2 min read
Most visitors arrive on a phone, often on mobile data. If the page takes too long, they go back to the search results and tap the next business. Speed is not a technical nicety; it decides whether you get the call.
What Core Web Vitals measure
Google uses three measurements of real visitor experience:
- Largest Contentful Paint (LCP): how long the main content takes to appear. Good is 2.5 seconds or less.
- Interaction to Next Paint (INP): how quickly the page responds when you tap. Good is 200 milliseconds or less.
- Cumulative Layout Shift (CLS): how much the page jumps around while loading. Good is 0.1 or less.
How to check your site
Search for PageSpeed Insights, enter your web address and look at the mobile result. It shows these three numbers and lists what is slowing the page down. Google Search Console has a Core Web Vitals report covering your whole site.
The usual causes of a slow site
- Large images that were never resized or compressed
- Too many plugins, trackers and chat widgets
- Heavy themes and page builders
- Cheap, overloaded hosting
- Sliders and autoplay video at the top of the page
- Fonts loaded from several different places
Fixes that make the biggest difference
- Resize and compress images, and use modern formats such as WebP
- Remove plugins and scripts you do not need
- Load maps, videos and chat only when the visitor scrolls to them
- Set width and height on images so the page does not jump
- Use a content delivery network
Does speed affect ranking?
Page experience is one of many signals Google uses, and good content still matters more. But a fast site keeps the visitors that ranking brings you, which is the part that pays.
