1. FCP (First Contentful Paint):–

FCP is the metric that measures the time from the start of page loading until it renders any part of the page content on the user’s screen.

A fast FCP score is like the first ray of hope for your users that helps them believe in what you are going to provide and what they are going to get in the first place. The faster the page loading speed, the better will be your FCP score.

2. LCP (Largest Contentful Paint):–

LCP metric measures the render time of the largest content being visible to the users when the page starts first loading.

A good FCP time is sometimes not enough. For instance, if your website shows a splash screen or loading indicator during the initial phase of loading, it will be not helpful for users. Therefore, LCP plays a more crucial role in retaining users on your website than FCP.

You need to make sure a speedy largest content loading of a web page of around 3-4 seconds to gain your user’s attention.

3. FID (First Input Delay):–

FID is the user interactivity metric that measures the phase between user first interaction with your website such as clicking on a link or tapping on a button until the time when browser responds to the result of the user’s interaction.

CLS is a measure of every unexpected layout shift that occurs during the entire lifespan of a page. A layout shift occurs any time a visible element changes its position from one place to the next.

A sudden change while reading an article or purchasing a product is the worst case that users can expect. Whether you see content text move or you’ve lost your place while clicking a link or a button, a shift at any point of your web page can end up resulting in a bad user experience. Therefore, CLS gives users an assured way of ensuring the visual stability of a web page.

Each website is different and requires different areas of concern. Thus, always analyze your specific problems before implementing any optimizations.

Reducing javascript execution can help you improve FID. If your report shows a poor FID score, that means your users might be interacting with a web page at over 300 milliseconds. This can be improved by reducing and optimizing your JS execution.

It’s also helpful to use as little memory as you can because when your site’s code requests the browser, it reserves a new memory that stops the JavaScript and might slow down the page.

One of the techniques to reduce JS execution according to Google is by deferring unused JS.

Do you use lots of images on your website? Make sure you’ve implemented lazy loading so that your site’s UX and core web vitals score won’t get harmed. Lazy loading allows the loading of images, animations, or videos only when users interact with them or at the moment when users scroll down through the page.

It does not compromise the website’s loading speed and help you achieve a high LCP score.

There are more benefits to lazy loading than just speeding up your page loading, here are some of them:

  • It will improve your site’s performance.
  • It will limit bandwidth usage.
  • will boost your site’s SEO.
  • It will reduce the bounce rate and help retain your visitors on the page.

Pages containing many heavy elements like images, animations, or videos, lazy loading is a must. However, there are no set rules for which pages lazy loading should be implemented.

So, if you are getting poor LCP, try implementing lazy loading and witness the positive results provided.

3. Optimize Your Website Images

Images are the largest elements of the content of some websites that don’t upload videos. Using informative images and designs is worthy of user attention but they must be optimized for fast loading time and better performance.

Image optimization carries huge importance and a variety of practices that make your page significantly lighter, improve LCP score, UX and ranking.

You can also reduce the page size by compressing images using any image compression software. Always consider using jpg format for landscape images and png for graphics. You can also use next-generation image formats such as JPEG 2000, JPEG XR, or WebP.

Apart from compressing your site images, there is another important factor to image optimization i.e. activating Content Delivery Network (CDN) for images.

CDN is a created network of servers all around the world that store your web content. Now that you have implemented CDN, distributed servers will render your images faster from the server closest to users.

4. Set proper dimensions for images and embeds

CLS score over 0.1 is considered poor, and usually, it is caused by elements like images, ads, or embeds without setting proper dimensions in the CSS file.

So, if you want to improve your CLS score, dimensions do matter. By giving proper width and height to your images or other embeds, the browser will help set the correct amount of spacing on the page while the element is loading.

For instance, with improper image size & dimensions, your site may experience layout shift or images may appear later on a page.

Apart from slow loading, the browser finds it hard to understand the needed space of that page. As a result, it immediately reduces the user’s experience.

So, in order to avoid this image shift, set the dimensions and provide a perfect space where the image should be displayed. Also, ensure setting dimensions of other embeds like videos according to what it requires, thereby preventing both front-end and back-end issues.

5. Speed up your server response time

The longer the browser takes to receive content from the server, the longer your site takes to render anything on the user end.

A faster server response time is directly connected to every single core web vital or metric. Google recommends server response times lower than 600 milliseconds.

Most importantly, long server response time not only affects UX but also SEO.

Time to First Byte (TTFB) is one such major metric that indicates the quality of server response time. TTFB measures the time when your user’s web browser receives the first byte of your page’s content.

So, it is good to gather data on your server’s current performance before you start and act accordingly.

Moreover, each plugin comes with additional CSS and scripts that add up to your page TTFB which negatively impacts your site’s performance.

So, take a look at the tips that will help you speed up your server response time, it includes, reviewing your plugins, checking how fast is your web hosting, and using CDN for your site.
