No one knows exactly how algorithms work. After all, if everyone had access to this information, the digital landscape would look very different. The factors that the world's most famous search engine uses to index pages are the Core Web Vitals. These are a kind of guidelines that you, as a website owner, must 'adhere' to in order to achieve a higher PageRank. The Core Web Vitals change every year. It is high time to kick off the new year with a blog about the Core Web Vitals of 2021!
Loading Speed (Largest Contentful Paint)
Google has introduced three Core Web Vitals: the LCP, FID, and CLS. The Largest Contentful Paint (LCP) focuses primarily on loading speed. The choice to address this first is a logical one. Just ask yourself: how likely are you to linger on a particular website if it takes too long for the homepage to appear?
Pages that load within 2,5 seconds are considered good, between 2,5 and 4 as mediocre, and anything above that is bad. By far the most well-known tool you can use to check how well your website scores on this is Page Speed Insights.
Interactivity (First Input Delay)
Another factor that is part of the 2021 Core Web Vitals is First Input Delay. In this context, however, we are referring to a completely different form of interactivity than the one you know from social media. Interactivity on websites means that something actually happens on the page. A button that lights up when you hover your mouse over it is a good example of this.
Generally, the faster a user takes action (clicking through, clicking an element), the better you perform according to Google. Reducing JavaScript files is one way to improve the First Input Delay score.
Visual stability (Cumulative Layout Shift)
Unlike the previous Core Web Vitals, the Cumulative Layout Shift is expressed as a number rather than a number of (milli)seconds. The less the various elements shift on a website, the better the Cumulative Layout Shift score becomes. The CLS is easy to reduce. You can achieve this by specifying the height and width dimensions of your content.
