Many web development and mobile app development companies are following this method for optmizing their content, in order to heighten the website demands among users.

In this, we will explore how to optimise web apps for each of the core web vitals. There are three core web vitals, which include: Largest Contentful paint(LCP), Interaction to next paint, and Cumulative Layout shift(CLS).

1. Largest contentful paint (LCP): This measures how long it takes for the largest visible content on the website to load. The LCP count should be less than 2.5 seconds for a better user experience and enhancement.
2. Interaction to next paint (INP): This helps in understanding how quickly the website responds to user interaction. Interaction to the next paint should be 200 milliseconds
3. Cumulative layout shift (CLS): Cumulative layout shift measures visual stability if the page by calculating the sum of all unexpected layout shifts that happened during the lifespan of the page.  The good score for a Cumulative layout paint is less than 0.1.

Now, let's look in more detail how we can optimize the each of the three main elements.  These elements when optmized is sure to bring you the best results with better SEO rankings.

Optimization for Largest contentful paint (LCP):

1. Image optimization: for optimising images use modern image formats such as webP and compressed images which have good quality. Along with it implement lazy loading for images and also ensure the images are appropriately sized for different devices.
2. Server response time: In this,  utilize a content delivery network (CDN) to deliver the content from locations closer to users, reducing the latency. Optimise server configurations and upgrade the host plan if necessary. Implement server side caching solutions to speed up the response time.
3. Minimise render blocking: render block can delay the process of rendering the page. To minimise it, identify and eliminate unnecessary CSS and Javascript.

Optimization for Interaction to next paint( INP)

1. Javascript optimization :  javascript needs to be optimized for better performance. Heavy javascripts can slow down the interactions. Break down the tasks into smaller chunks.
2. Remove unnecessary unused plugins that may create unwanted bloat to all the applications.
3. Simplify the HTML structure by the reduction of the number of elements.

Optimization for cumulative Layout shift (CLS)

1. Set a size for the ads and the images: set an explicit dimensions for the images and the ads.
