INP & CLS Improve

[Jayesh Patidar]

Hello,

We have implemented all possible optimizations to improve the INP and CLS scores on the website below, but the mobile performance metrics have not improved.

We have completed all the recommended fixes, yet the Core Web Vitals are still not showing as Good (green) for mobile.

Could someone please help us identify the root cause of this issue and determine what is preventing the mobile metrics from improving?

We know some JS are loding on this domain but this also loding on category page and product listing page but there is everything is fine. Only problem exist on home page.

Any help will be appreciated to fix it.

Hi,

I think you should inform these issues with the theme development company. They can tell you the reason.

After that you can make the changes as per by that theme development company.

For CLS, we give some advice here: https://web.dev/articles/optimize-cls

In particular I notice CLS is fine on load, but if your scroll, you clearly see a CLS issue:

This is usually a classic sign of lazy loading without reserving the space.

It looks like the Beauty Blog section loads late (even though it is in the original HTML?) and this shifts the call to action down if that happens after you've scrolled to this section.

For INP the search bar looks slow when I throttle my PC and start typing:

Usually that means you need to debounce to prevent a queue of search results building up as you type.

Michal Mocny covered this exact use case here: https://www.youtube.com/watch?v=KZ1kxzsJZ5g&t=222s. The technology you use might differ, but the techniques and principles will still be valid.

The best was to diagnose Core Web Vitals issues (particularly for INP, and late CLS, which depends on user interaction and so are difficult to diagnose with a tool) is with a RUM solution. They can provide details as to what pages, and what elements on the page are causing issues. This can take a lot of the guess work out of diagnosing performance issues.

There are many great, commercial RUM solutions which not only collect the data for you, but also present it in dashboards to understand it. I see you're using Cloudflare and believe they have an analytics solution available for sites running on their infrastructure so that might be the easiest solution, especially as I think it's even available on their free tier.

Once you have narrowed down the issue, it's a matter of repeating it locally and trying to identify the cause. And in some cases it might be a matter of contacting the third-party provider (if it's their widget causing the issues, like it might be with your Search widget if that's third-party provided?) and seeing if they're aware of issues and have any advice or plans to fix it.

Hi Barry,

We have fixed the blog issue, but we're still not sure about the exact root cause of the INP problem.

Is there any free tool available that can help us identify the exact issues affecting all Core Web Vitals metrics? It would be really helpful for diagnosing performance problems more accurately.

Based on your suggestion, we've already started investigating the search functionality, and we'll continue to monitor it. If you have any additional recommendations or insights based on your analysis, we'd really appreciate them. They would be very helpful in identifying and fixing these kinds of issues in the future.

Thank you!
