Tools to Measure Core Web Vitals
Internet is the deep sea where you can find anything but you need to give some effort to get the best result. Google also helps us by providing various tools to improve user experience. We categorized the testing of any website in two terms one is Lab Tools and the other is Field Tools.
Lab Tools: It provides the performance of any website during the development phase.
Field Tools: Its main work is to displaying the data to the website owner to improve the results.
Below are some tools from which you can easily measure your Core Web Vitals and improve them according to the suggestions given by the tools.
How To Optimize Core Web Vitals
As you know CWV is used to measure the user experience on the website. So we need to work on improving the user experience in these 3 vitals that play a major role in user experience.
Largest Contentful Paint (LCP) – Loading
LCP is how long it takes a page to load from the user’s perspective. It means it is the time when you click on a link to see the content on the website. LCP is a bit different from other page speed measurements. LCP majorly focuses on page speed to see and interact with your page. You can also check your LCP score using Google Pagespeed Insights.
- LCP refers to the largest piece of content on a page(Featured Image, Videos, etc)
- An image or video that takes the maximum time to render as page loads.
- 2.5 sec (good) & above 4sec poor.
Ways To Improve LCP Score
- Upgrade your web host
- Remove any unnecessarily third-party script.
- Minimize your CSS and set up lazy loading.
- Remove large page elements.
First Input Delay (FID) – Interactivity
FID is Google’s second core web vital. FID measures the experience of a user when trying to interact with a partially loaded page. FID is important for Google because it gives accurate data on how real users interact with websites.
- Responsiveness of the page when the user first tries to interact with it for example clicking the read more link.
- FID is less than 100ms
Ways To Improve FID Score
- Minify Javascript
- Use browser cache.
- Remove third-party scripts.
Cumulative Layout Shift (CLS) – Visual Stability
If the elements on your page move around as the page loads then the CLS is high and it is bad for the overall user experience. It happens when a user experiences a shift in the layout after a page loads the CSS You have stable your page elements as it’s loads up.
- Images and Videos without dimensions
- Ads embeds, and iframes without dimensions
- Dynamically injected content
- Web Fonts causing FOIT/FOUT
- Actions waiting for a network response before updating DOM
Ways To Improve CLS Score
- You have to ensure that the ads element has a reserved place.
- You have to edit new elements below the fold.
- You have to set the size, dimensions for a media (GIFs, video, images, etc. )
