So how are we fixing the INP issues
Hmm, so LoAF will tell you what's causing them and then you go from there. Seeing a third-party script? Check if you need the third-party, check if you're causing the delay or if it's the vendor's fault, contact the vendor to ask them to optimize it or switch to a different vendor. You own code causing delays? Work with your dev team to see if they can optimize it. Whether that's just by avoiding unnecessary work or by using techniques like bundle splitting or scheduler.yield to reduce the impact of the processing on INP.
@@debugbear Got it. So usually with thrid party scripts it is probably going to be the vendor that is causing the issues with code that doesn't have performance in mind. How would we check if we are causing it?
@@danielstrongin8525 Hmm, there are two scenarios. 1. You do a DevTools profile and check what code is running at that point (i.e. at the bottom of the call stack rather than the third party at the top). Is that your own custom code that's triggered by the third party, or is it code that's directly caused by the third party? 2. Sometimes code will run because of how you've configured the third party, so there'd be shared responsibility. Either you can change the settings or talk to the vendor to see why a specific setting is slowing the code down.
Hi Matt! It’s Alla
Hey! Thanks for checking out the video!!
@ it’s very good and informative as always
hmm, the first thing I thought of was multistep form animation step transition without JS
How much of this do you think is attributed to server time such as shared hosting vs dedicated hosting rather than on page optimization or is it both?
Glad someone is creating single page without any framework! New versions of JS are totally different from JS 15years ago, with features like templates you don't really need any framework and you skip massive bloat of JS tooling and all the problems that comes with it.
Thank you, this hasms been incredibly useful for me

it's work all browser

what is it that you uploaded? for what purpose?
Do you mean the override? It basically replaces the file for the website on your side when a webpage loads. You can use it for mock fetch data
Thank you 😊

@umarHansa I can only see LCP by phase tab. Can't see that LCP request discovery tab. Any ideas why?
What if the lcp is affecting a background image will I do the same thing?
Hi there. Great tutorial. I'm looking to make these changes for my webflow website. At first I thought I needed to add the fetchpriority attribute to my hero (which contains the image) but that doesn't seem to work according to debugbear (still showing as low priority on analysis). Do you know how I can make these changes? Is it as simple as dropping this <link/> in my header? What if the LCP is a different image (such as a background that varies depending on the blog post I'm viewing)? How can I have a fetchpriority for a different image for each page?
which version of chrome are you using ?
This works in Chrome stable v128, but you'll still need to enable the experiments, as shown in the video at 11:25
@@UmarHansa Using 128, I do not have the "enable performance insights" experimental flag he enables at that timestamp.

It depends, but in simple words, maybe you can do code optimizations, see the html elements you render in Doom, logic and javascript code..., etc...
Thanks for this insightful video on CWV. Would be great if you could make one video focusing on mobile as well. Can this be done?

Hi mate. Thank you for the content. I use Elementor on WP. Would you be able to make a video explaining how you would change each of these things in my case please?
It would be really helpful to see how you implement the fetchpriority. I can see it's helpful, but none the wiser how to implement it.
Hello James, we have a short video on how to implement fetchpriority. You can also find more information on our blog.
Thanks for the great explanation 👍👍
Thank you, Joey!

Hello, which tools did you use to view the request list?
This is a DebugBear request waterfall, you can create one for your website with our free site speed test: www.debugbear.com/test/website-speed
The fetchpriority worked perfectly, thank you!!
Can it be done to WordPress also?
Awesome!
You should be able to add fetchpriority with a WordPress site.
@@debugbear what is fetch priority, How could it be done within WordPress?
Breaking it down like this is really clever. Great vid!
Thanks a lot!
nice demo! reminds me it is about time I make a demo video of decareto…!
