The loading speed of a web page is a key factor in natural referencing . Google favors, in its results pages, sites that provide the most intuitive and easy user experience possible. If several metric indices are used to calculate the display speed of the elements of a site, they do not allow to understand the interactivity of the site. The search engine has thus deployed a new metric: Time to Interactive (TTI) . Many sites tend to value the visibility of content to the detriment of the ease of interacting with it. Still, it can create a pretty frustrating user experience . In particular, when the Internet user has the impression of being able to act on the elements of the page, but that nothing happens.
Google therefore now takes into account in its referencing algorithm the speed index, but also the “Time to interactive” . The time to Qatar Email List interactive is a measure which thus makes it possible to calculate the time between the start of loading your page and the moment when the user will be able to fully interact with your site; and this for at least 5 seconds! Google defines, in fact, this interactivity as the moment from which: the page displays the first useful contents, which is a data defined by the First Contentful Paint. it is possible to interact with the most visible elements of the page, that is to say the moment when you can click on visible content.
What is the “Time to Interactive” measurement?
the page responds to the user’s interactions within 50 milliseconds, that is to say the moment when an event is going to occur, reactively, when the Internet user clicks on the element. In other words, the interaction time is calculated between the display of the first significant element (such as a text, a title or an image) and the moment when an action can take place quickly on the screen when we click on an element. . For example, a new page opens or an animation starts. The shorter this delay, the more satisfactory the experience will be for the user. On average, according to the search engine, the delay before interactivity should not exceed 2 to 3 seconds .
The delay to interactivity is a new metric that still needs to be refined. Human perception of a site’s loading speed is not an exact measure. It relates to each user depending on the device used as: his browser, its internet connection, its own appreciation of the loading speed. It is therefore difficult to correlate the indicator given by the TTI and what is really happening on the user’s screen. The TTI is therefore not yet integrated into all measurement tools. Google’s new tool, Page Speed Insights , still allows you to access this data. However, do not interpret it literally, because it is not a standard measurement.
How to measure the delay before interactivity?
Rather, it should guide your SEO optimization work . As the TTI is a difficult measure to observe in practice, some developers and SEOs prefer the First Input Delay . The FIP measures the time between when the user first interacts with the site and when the browser responds to this interaction . In other words, this metric only allows you to measure the page reaction time to a request from the Internet user. This data depends on fewer factors than the time to interactive, it is therefore more precise and more reliable. However, it does not give the actual time within which a website is ready to receive an interaction AND respond to it. How to optimize the Time to interactive of your website?
