Google 2021 Core Web Vitals Update Complete

Core Web Vitals Update now fully rolled out

Google has announced that its latest core update is complete. The company said the update was implemented between July 1st and 12th.

Google has preliminary reports that the July 2021 core update is now “effectively complete.” Google wrote on the Search Liaison Twitter account”.

Core Web Vitals Update

The core web vitals cover different aspects of the user experience, including page load speed and visual stability. Core web vitals metrics include LCP (largest contentful paint), FID (first input delay), and CLS (cumulative layout shift).

Hundreds of changes are made every year to the way websites interact with Google’s algorithms and how these changes affect end users. This not only has a positive impact on customer experience but also encourages businesses to look favourably at improving their content and delivering it in a better manner.

Google started to roll out the July 2021 core update on Wednesday, July 1, at around noon. It finished rolling out today at around 1 pm ET

International global updates are not specific to any region or language. They affect all websites and systems with Google software installed worldwide.

It is a classic “broad core update” that Google releases several times annually. The most recent one before the back-to-back June and July updates were six months ago.

Based on what we’ve seen, it seems this July update was felt in a big way on July 2, 2021, and then again on July 9, 2021, and July 12, 2021. So if you saw big changes to your rankings between July 1 and July 12, 2021, especially on July 2nd and 9th – it was likely related to this July 2021 core update.

In our previous article, Why Is The Speed Of Your Website So Important we discussed why this is an important consideration.


With no universal tool to track core web vitals, you need a variety of tools- PageSpeed Insights, Search Console, Chrome UX Report, Lighthouse and Chrome DevTools. Furthermore, test the page experience by using several key signals:

  • Understanding and resolving any core web vitals security issues through the search console (security issues report).
  • See if your website is using HTTPS instead of HTTP.
  • Use online tools to gauge how mobile-friendly your website is. The more the better as this ensures a great user experience across different platforms.
  • Get rid of any interstitials by following the required interstitial guidelines.


According to research from SimilarWeb, “page experience signal” is the quality of how efficient a website is with interactivity. Websites that are fast and responsive give users a better user experience.

Google Page Spped

Google rates the speed of a site largely based on how many visitors are browsing it. Improve your page loading times and Google will see an improvement in your rank.

The report concluded that core web vitals will be combining with existing signals like safe browsing, mobile-friendliness, HTTPS security and interstitial rules to give you a better way of optimizing your site.

As per recent reports “core web vitals” will merge with these other factors such as well-known web browser security rating systems.

This is not to say that the new core web vitals metric will replace the relevance and quality of your content, as it remains one of the most important ranking factors. However, moving forward Google takes into consideration how well you keep your customers happy by looking at a wide variety of signals while assessing where to rank your site in search results.

What to do if you are hit. 

In the past, Google has offered advice to sites impacted by a core update, namely that no one knows what caused the loss of rankings and any areas for improvement are likely tied more to overall site management rather than just their ability to recover. In reality, there’s not much you can do as some sites see an increase in ranking after a downgrade.


The Core Web Vitals update will require optimizing your site for the best business experience. However, this also presents a perfect opportunity to see an even wider audience for your content.

Latest interactive websites provide a user-friendly experience for their visitors and improve the stability of the site.
