INP – a new indicator in Core Web Vitals
According to the latest news from Google, they are preparing to make changes to Core Web Vitals as early as March 2024. The changes include the introduction of a new INP indicator, which measures how quickly a site responds to user interactions. This is an important parameter that reflects the fluidity and responsiveness of a site, which is crucial to a user’s experience on a website.
Differences between INP and FID
Here it’s worth noting that INP (Interaction to Next Paint) and FID (First Input Delay) are two important Core Web Vitals metrics that measure website interactivity, but they differ in many ways. INP takes into account all user interactions during a session and then selects the worst response time per interaction to better reflect the real user experience, while FID focuses only on the first user interaction, not taking into account any subsequent actions taken by the user. INP, on the other hand, measures a site’s response time to user interactions throughout the entire user experience, while FID is limited to the response latency time to the first user interaction. INP gives a more comprehensive view of a site’s interactivity throughout its use, taking into account all actions taken by the user, unlike FID, which focuses on the initial response latency to the first user interaction
How to measure and improve performance?
The INP score is measured using website performance monitoring tools such as Google PageSpeed Insights or browser developer tools. The INP score is expressed in milliseconds and should be as low as possible to ensure an optimal user experience. To improve INP, a number of steps can be taken to optimize the interactivity of the site. JavaScript code should be optimized, resource requests should be minimized and delayed, blocking of the main thread should be avoided, and asynchronous loading techniques should be used.
The importance of INP for SEO
INP is important for SEO because Google is increasingly emphasizing user experience as a ranking factor. Websites with a fast and fluid user interface will have an advantage in search results.
Summary
INP, or Input Timing, is a new Core Web Vitals indicator that measures how long a site takes to respond to user interactions. It is an important parameter that affects the user experience and can have a significant impact on a site’s position in Google search results. Therefore, it is important to monitor and optimize INP to ensure the best possible user experience on a website.
