Below tools you can use to audit your site speed. These tools will provide a detailed report where you can be done for improvement for the site speed.
  • GTmetrix
  • Pingdom
  • Google – PageSpeed Insight
  • Web Page Test
Let’s see in detail about each tool.
GTmetrix is a simple online tool that can be used to test website load time. You can enter your site url and click on Test your site, it will analyse the site and show you report. GTmetrix offers details on which aspects your site is taking more time to load and provides a detailed report with the recommendation. By referring to the recommendation report you can work out and apply fixes.
As soon as the page is scanned by the tool, you will get a summary of key performance indicators and website monitoring. Furthermore, this powerful web speed test tool also includes more useful functions:
  • Keep track of page performance with monitoring, graphs, and alerts
  • Test pages from different regions

Gtmetrix audit report will focus on Core Web Vitals. As per google update these web vitals are very important to rank the site in google. So you have to understand that and improve. You can refer to our blog for more information about core web vitals and why it is important?
As per GTMetrix report there are three core web vitals.
  • Large Contentful Paint(LCP)
  • First Input Delay (FID)
  • Cumulative Layout Shift (CLS)
The three Core Web Vitals are:

1. Largest Contentful Paint

LCP measures how long the page takes to load from a user perspective. Generally it refers to the time to take the load with the largest image or text block visible to the user. As per google standard LCP should load within 1.5 seconds, if it takes more than that then definitely you should workout to improve the LCP.
LCP is decided by factors such as the render time and the largest video, image, and text in the user’s visible area of a web page.Google looks at this metric to find out how long it takes for the largest piece of content to load, regardless of the size of the device or the type of content on the page. LCP can be impacted by your CSS, your server time, and client-side rendering.
LCP of: As per above image, LCP of Less than or equal to 2.5 seconds is regarded as fast.Between 2.6 seconds to 4.0 seconds needs optimization. Greater than 4.0 seconds are considered slow.

2. First Input Delay

First Input Delay measures how responsive your website is, once a user clicks on a link, taps a button or any other interaction with the page. What is the delay between the interaction and the result of the website actually doing something. Anything less than 100ms is considered good, anything over 300ms is poor and should be addressed with priority.

3. Cumulative Layout Shift

CLS measures the visual stability of a webpage. Does the page shift as you scroll, do you go to click a link for it to move before you’ve clicked it. This usually happens because things are still loading in the background. Visual stability is a frustration for users as it can cause confusion – or worse – incorrect use of the site, form, or application. CLS is a score between 0 and 1 based on the element’s moving distance and visual impact in the viewport. A score of 0.1 or less is good, and anything over 0.25 is considered poor.
LCP of: As per above image, LCP of Less than or equal to 2.5 seconds is regarded as fast.Between 2.6 seconds to 4.0 seconds needs optimization. Greater than 4.0 seconds are considered slow.
