FID measures how many background tasks are causing a user’s first action (such as clicking a button or typing a character) to be delayed. Therefore, the FID measures the delay before the event and not the delay in the user’s first action. In other words, a user’s interactivity is delayed because the browser is busy Dom building or executing other background tasks at the time of the interaction.


CLS measures the amount of re-flow on your site to reduce any unintended user clicks. A re-flow is an immediate change in the appearance or layout of a page. For example, if you’re on a site where the header banner hasn’t been loaded yet, and you click on a link, the header image gets loaded and pushes all other content down. If you clicked during the reflow, chances are you ended up clicking on a different link than the one intended.


This LCP measures when a good part of the screen is visible to the user. Often, for eCommerce sites, this is when the hero image starts to appear or when the carousel image appears.

While these new metrics may be important for UX and Google Search, attention should be paid to other performance metrics that also impact user experience, and ultimately more business-driven metrics, such as conversion rates.

There are a few tips and pointers that you must follow so that you can get the most out of your website’s optimization needs.

1. Site performance metrics should be continuously evaluated

You should always be constantly evaluating the philosophy of your website. Small things sometimes indicate big problems and by bringing the image to mind quickly, you should think about solving those problems before they develop. This can become a serious concern for your users’ experience. In addition, you’ll also need to track gradual improvements to your site’s metrics.

Of course, your website cannot be changed overnight. But if you keep track of regular improvements, it can help you decide whether your efforts are paying off, or whether you need to change your approach or do something else.

This will help boost sales for your site, as well as its main, Can also improve metrics and overall performance.

3. Content size should be kept low

One should try to keep the ingredients to a minimum. We don’t mean to say minimally that you should remove images from your side, but you should try to minimize them where possible. The bigger the image on your website, the slower your website will run large images of yours, especially for mobile devices. For this, trying to reduce the size of the images can help. Compacting the file sizes for images can also be a great help in this regard.

4. Organize your web page layout

You should always be sure that your website is loading the content in the order that the readers see the content. If the content at the bottom of the page takes a few seconds longer to load, there’s a good enough chance that it won’t affect your site visitors, they won’t see it right away! However, if the content at the bottom of the page is loading before the content that is immediately visible to your visitor, you are looking at a problem that needs to be tackled as quickly as possible.

5. Can postpone your scripts

This should let you determine in advance which scripts do not need to be loaded immediately. It is likely to be some third-party libraries, trackers, etc. However, also be aware that they are not associated with a function that would give you runtime errors.

You can also use ‘sync’ to run libraries asynchronously, which are executed after download. It differs slightly from deferring in that it does not wait for the page to be fully parsed before running.

6. You can use lazy loading

Lazy loading will certainly help reduce your initial loading of images by delaying initialization until necessary. This conserves the user’s bandwidth and will allow for faster page loads. Most modern browsers support lazy loading natively. You just add a loading=”lazy” to your <img> tag.


<img src=”your-image.jpg” alt=”your-image” loading=”lazy”>

Also, note that not all browsers support the feature, so you can consider LazyLoad or Blazy or any other library. They are both lightweight libraries that will work in all browsers.

7. Must use CDN

A lot of your well-known tools and libraries will already have links to a CDN. More often than not, these tools will provide you with a link. There is a good chance that the library may also be cached on the user’s end by visiting other sites. This will greatly improve load times.

8. Make your site mobile friendly

A common problem with adapting a site to mobile devices is the responsiveness of site structures and images. Therefore, you should also keep your website mobile friendly and its score should be good so that even if a buyer gets the website loaded on his mobile phone, he gets a good experience.

9. Fix security issues

Security issues can manifest in many ways, so after running a security issue report in Google Search Console, you should follow any necessary checks via google for this.

10. Should remove annoying intermediate

This can be corrected easily. If your pop-ups are covering most or all of the page’s content, make them smaller. If they are unresponsive and block content, remove them. Do not include interstitial ads above the fold that impede access to the content.
