This will make your website load much faster. On websites hosted away from the user, it is worth opting for a CDN. It is a service to which any website owner can subscribe to bring together, in the sense of the server, the user’s information. Over long distances, the server behaves much more efficiently . In cases where the larger content is an image, compressing and shrinking the image greatly helps to achieve a lower LCP score . On some content, it is even preferable not to display an image at the start of the page. This is especially true on mobile for blog posts . In this case, favor purely textual content (much faster to load than an image) to possibly place an image later, lower on the page.

Converting images to current formats also offers good performance and saves you a few milliseconds of loading time: so opt for JPEG2000 or WebP . The FID indicator: for responsiveness A page that quickly displays its elements does not Djibouti Email List necessarily mean a responsive site . Indeed, the reaction of the page “to the very first click” made by the user is another element that must be taken into account to judge the responsiveness of the site. This is precisely the raison d’être of FID. FID experience pageThe FID is also called TBT for Total Blocking Time. This is particularly the case on Semrush. but that does not change the indicator itself! The purpose of the FID (for First Input Delay) is to calculate the time it takes for the site to react to the very first stimulus when the user arrives on the page .

The CLS indicator: for visual stability

More precisely, it calculates the delay between the moment when the user interacts with the page just after arriving there (in full loading time, therefore) and the moment when the site is able to respond to this interaction. This interaction can take several forms: click on a button, click on a link, click on an image to enlarge it … By analyzing the very first input, this metric focuses on the “first impression” value. Indeed, a website rarely has response latencies to clicks after loading. So it makes sense to analyze what happens in the user’s very first moments on the site. In addition, it is often the user’s first impression of the site that will determine whether he likes it or not . Google has understood this well and therefore focuses on this first impression value in its calculations.

To be green on this metric, a site must have an FID of less than 100 ms. Improve your FID score The JavaScript which occupies the main thread is the major cause of inactivity of the site in the face of user clicks. Indeed, it is when the main thread has to manage JavaScript requests that it is unable to respond to the Internet user. In this case, it is at the level of JavaScript that you can act. FID experience score page representation of the activity of the main thread (in yellow). If the Internet user clicks while the thread is handling a server request, then he waits for the thread to finish its calculation so that the latter takes into account the Internet user’s request. The first solution is to reduce the weight of JavaScript files as much as possible .

To conclude on the Google Page Experience: always think globally.

This is a process that cleans up the code by removing anything that is superfluous: code that does not refer to anything, developer comments, line breaks, and other unnecessary layouts … In addition, defer loading unused JavaScript at the start of the page or for plugins. This is often the case for WordPress sites which are very heavy on JavaScript, due to the many plugins installed. If there is one point on which all users agree, it is that jumping frames and moving elements on a web page are extremely annoying . This is all the more true on mobile! In order to take this disruptive element into account, Google created the CLS indicator , standing for Cumulative Layout Shift.

page experience key visual stabilityThe CLS is not a time indicator like the other 2, but an index based on a very simple calculation, detailed just a little lower! The latter focuses on how often elements move unexpectedly, causing great discomfort. Such shifts occur during the page loading phase and come from the fact that all the “components” do not have dimensions known in advance during the development phase: the responsive in particular forces many elements to adapt to screen dimensions. Therefore, when an element loads and is displayed on the screen, it moves all the other elements under it and which were loaded before it. The layout shift score is calculated from 2 measurements of movement: the Impact Fraction measurement , which calculates the total area that an element occupies on the screen in the initial position and in the final position.
