Core Web Vitals are a set of essential factors specifically observed by Google to check the global user experience of a web page. Core Web Vitals are formed with four measurements related to the page speed and user interaction. These include: First Contentful Paint, Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.
To reflect real-time user experience, Core Web Vitals are applied to all web pages. These must be measured by all site owners and will be surfaced in all Google tools. Each Core Web Vital indicates a distinct side of the user experience.
Core Web Vitals do not work alone, as there are many other measures. After making a lot of research, Google determined a new set called Web Vitals. It is a combination of existing and a new set of measures. The three Core Web Vitals are highly important, and Google specifically asks website owners to keep an eye out for these scores and improve them where they can.
When you click on the open report in Mobile or Desktop, you can see the issues which caused a bad URL. And resolving those factors can lead you to the improvement of your URL.
There are two types of errors generated in Core Web Vitals
- CLS issue more than 0.1s (desktop)
- LCP issue longer than 2.5s (desktop)
You can see only 20 URLs in the Core Web Vitals report.
After clicking on the “CLS issue more than 0.1s (desktop)”, then you can see which URL affected the CLS issue. We can discuss these issues in FCP, LCP, CLS, and FID section.
You can see the issues that caused a bad URL by clicking on the open report in Mobile or Desktop. And resolving those issues can lead to an increase in the quality of your URL.
There are two tools used for URL improvements
- Page Speed Insights
- GT Metrix
Page Speed Insights
You can write this URL https://developers.google.com/speed/pagespeed/insights/ in your address bar
Once you enter your URL in the textbox, click on the Analyze.
After click on analyze, your report would get generated and you can simply check your URL if it is poor or good and where it needs an improvement.
Here, this URL has turned out to be a good one.
However, on the flip side, you can improve your URL considering the steps of the FCP, LCP, FID, and CLS sections.
The GTmetrix works as similar as page speed insights but GTmetrix follows different algorithms for Core Web Vitals. You can write this URL https://gtmetrix.com/ in your address bar
If you log in to the GTmetrix, you can compare your previous URL performance with recent URL performance. Now, enter that URL in the textbox and click on Analyze.
You can see a generated report with various grades such as A, B, C, D, E.
Here, this URL is on A-grade, which steps we can follow for the improvement for our URL, you can be following in the FCP, LCP, FID, and CLS section.
As we can see this URL is of A grade. Now let’s discuss in detail the four improvement steps of Core Web Vitals i.e.,
- First Contentful Paint (FCP)
- Largest Contentful Paint (LCP)
- First Input Delay (FID)
- Cumulative Layout Shift (CLS)
