Digital Marketing » Blog » Search Engine Optimisation Coming in 2021, Core Web Vitals is Google’s latest change to its ever-evolving algorithm. Unlike other updates, what sets the Core Web Vitals update apart from the regular core algorithm updates, is that Google has given us over 6 months to prepare for this one, raising the stakes as this is often an indication of how important Google would consider this update. Core Web Vitals essentially looks at user-experience metrics determining how user friendly a page is, it consists of three main components: This simply refers to the time taken for the page to load from the perspective of the user. In simple terms, it is the time taken for the bulk of the content of a particular page to load for the user. What, perhaps, sets LCP aside from other pagespeed measurements is that it only considers loading time of page elements that directly impact the user experience, e.g. images, videos, background images with CSS, plain text etc. One of the easiest ways to measure your LCP is through Google’s PageSpeed insights tool or through Google Search Console itself. The following tools from Google give us a pretty good understanding of site performance. Although good scores vary from site to site it has been made clear that anything under 4 seconds would be considered acceptable whereas 2.5 seconds would be the ideal time for LCP. First Input Delay measures how interactive a page is, Google is essentially aiming to measure how quickly a page can produce an outcome from interaction with the user. For example, interactions may include choosing an option from the navigation menu, clicking a link on the homepage or signing up for an account, amongst others. Google determines a poor experience as on whereby we click on an event button, and there is a significant delay in terms of load time. For sites that are purely content-based such as news articles and blogs the importance of FID is somewhat reduced as there is little interaction to be made on the page, however, for E-commerce sites, this is a crucial ranking factor. Google has made it clear that FID First Input Delay (FID) measures the time from the users’ first interaction on your site (e.g. upon clicking or tapping on a button ) to the time when the browser is actually able to respond to that interaction. The ideal time is >100ms with anything above 300ms as a response time considered poor. Minimize (or defer) JavaScript: By parsing or deferring your JavaScript, we can enable users to interact quickly with our site, thus helping keep our FID low. Remove any non-critical third-party scripts: Just like with FCP, third-party scripts (like Google Analytics, heatmaps etc.) can negatively impact FID. Leverage Browser Caching: Through caching, we allow users to save and reuse files included on our sites. This would significantly reduce load time and positively impact FID. CLS measures how stable a page remains after loading. Google considers unexpected changes in the page layout, such as the page shifting or image sizes changing as very poor user experience. By ensuring the page loads in a stable manner, users are able to act quickly and reduce errors in terms of incorrect clicks. This is particularly crucial on mobile devices where unstable elements can cause a very poor user experience and with the limited screen size, the impact of this is amplified on for the user. This would result in a higher bounce rate, lower interaction, as well as a poor CLS score. CLS can be measured through PageSpeed Insights as well as other lab tools such as GTMetrix which give us a clear indication of site performance on this metric. Google has indicated that a good score is >0.1 seconds with anything above 0.25 seconds being considered poor. With around 6 months to go for the Core Web Vitals update to be rolled out, it is crucial to analyse your current site performance with regards to LCP, FID and CLS. The changes outlined in this article can go a long way in terms of improving site performance and ultimately user experience. One thing is for sure, Core Web Vitals will be one of the most significant updates in terms of ranking factors, and it is crucial to take this into consideration going forward.
