Google’s latest algorithm update focused on the user experience introduced the Core Web Vitals as an SEO positioning factor. These new metrics focus on improving aspects that facilitate the use of websites, such as page loading speed, as well as the stability of all its elements when loading.
With the recent changes, Google’s algorithm ranks better those pages and websites with fast loading times that offer better user experience.
Core Web Vitals are made up of three distinct metrics: Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS). All of them are metrics dedicated to the user experience, specifically to the loading speed of pages and websites, as this is one of the main factors that Google will be looking at from now on when it comes to positioning on the search results page.
How to improve the loading speed of a web page
-Dynamic content and ads: CLS measures the time it takes to load dynamic content (embedded YouTube videos) and also ads. For these elements to load correctly and not affect performance, it is necessary to configure the size and aspect ratio of the “boxes” that contain them using CSS.
-Do without plugins: While plugins can be the solution to many problems, too many can cause long load times and poor performance (even leading to 500 errors). Excessive use of plugins can increase server response time, which will affect the FID score. It is important to review the use of plugins and remove all unnecessary plugins.
-Images: Images uploaded at full size and not optimized affect the LCP score, as they are very heavy elements that take a long time to load. When uploading an image, the best thing to do is to resize it to the indicated size and reduce the “weight” as much as possible.
