How to pass Core Web Vitals?
Core Web Vitals is the latest screening process that websites have to achieve a higher ranking in the Google search.
It will officially be active by May 2021, and every website will get ranked either “Good,” “Needs Improvement,” or “Poor.” All this is done by analyzing the CRUX reports' data (Chrome User Experience Reports).
Google launched core web vitals after conducting in-depth research on the industry. It was seen that users inclined towards sites that offer them a better user experience. Keeping the results in mind, Google came up with three metrics that every website has to go through, and these are:
- Largest Contentful Point (LCP): It is the aggregate of time a page takes to render itself and load all typical elements like image, video, or large block text. The LCP should load at least 75% within 2.5 seconds. I’ve written a detailed guide on Largest Contentful Paint WordPress, which helps anyone achieve a good score without the need of developers.
- First Input Delay (FID): This metric focuses on the interactivity of your page. It measures your website's total time to respond after the user has clicked on a link. The ideal FID should be less than 100 milliseconds.
- Cumulative Layout Shift (CLS): This focuses on how much your page layout shifts in the process of loading. It is measured in either 0 (no shifting) or 1 (most shifting). The pages should score less than 0.1 seconds to qualify the CLS metric.
Core Web Vitals Case studies
Tokopedia- It is among the biggest e-commerce companies in Indonesia. The page has over 50M+ monthly page views.
According to the latest Google algorithm, the company has revamped its website and has achieved 35% more Click Through Rate (CTR) with an 8% increase in conversions.
They have used an extensive framework to achieve these results. The updates have immensely improved the performance of its website.
NDTV- It is a very famous Indian news channel that has over 200M users. It was essential for NDTV to upgrade to the standards of CWV metrics.
After this, the website received a boost of 55% in their LCP, followed by a decrease in the 50% bounce rate. They used tools like the web.dev/measure, WebpageTest and PageSpeed Insights.
It increased the consumption and engagement of content and hence increased their revenue. The LCP score went down from 3 seconds to 1.6 seconds after the optimization.
Shopify– This case study analyzes the CWV scores of all Shopify themes by doing multiple tests in a day. The results are fascinating to read.
Core Web Vital metrics' launch is essential to help website owners understand the user experience while browsing your website. These were some of the latest stats that could help you better understand the necessity of CWV and why you should implement it.
