12:25 - Point where the practical advise starts 18:19 - Real website case study

Extremely simple and helpful explanation. I could bring the LCP that used to stay between 3.5 to 4s, down to 1.5 to 2s. Thanks a lot for creating this video!

Thank you so much. You gave me the tools that I need to learn, apply the learning, and combine other functions and information.

thank you for simple and practical advices. i hope you have simple and practical guidance along your way.

Really clear, well done Philip!

What a really good talk Phil. Sending it to everyone. :P Thank you.

Thank you for the video; I really liked the practical example at the end and the various breakdowns. 🙂

This was brilliant! Loved the structure of the video and the optimization of the demo at the end!

I miss your content @YouCodeThings

I can't exaggerate how helpful this type of learning- and practical material is for us to improve our user experiences and ultimately improving the bottom line (for all you PM's out there). I would strongly urge and request (beg?) that the same format is made but for INP, as we're getting closer to March 2024 and INP becoming de-facto part of Core Web Vitals. Thanks for the extremely well produced and explained material. More of this will make the web a better place for everyone.

Amazing, such a great video... Thanks for the insights on this topic

Thank you for this video its very interesting, but i hava a qestion where I can get perf.js file????

Can you give basic instructions to non-coders on how to install the perf.js code with a wordpress site? Thanks

Wonderful illustrations and much appreciated. Are there tools within the Performance test that can help track down the element_render_delay? Looking to pinpoint the javascript files or functions could be causing a long LCP? A stack trace leading to the LCP?

Very helpful. Thank you Phillip.

Wow. So helpful. Thank you very much!

anyone knows when this bug "LCP_SUB_PARTS.forEach(performance.clearMeasures);" can be fixed?

Hi is there a video for optimizing website banner images to pass the page insight?

תודה רבה, הטיפ הזה על טעינה מראש של תמונות הביא לי לפחות 10 נקודות. כל הזמן הזה ניסיתי לעכב את הטעינה של תמונה בראש הדף במקום לנסות לטעון אותה יותר מהר. 👍

For those looking for the perf js file, you'll need to type it out yourself which is shown fully on the screen The file is only 36 lines I searched on the linked article, the author's github, and the co-author's github and I was unable to find this file

I typed in verbatim the code and it didn't work for me. I'm pretty sure I had everything right; I even put it in chatGPT to make sure I didn't have any typos. Realized that the Web Vitals Extension on Chrome already does this anyway, so no need for the script.

How do we fix LCP Preload Largest Contentful Paint image when using native web components I have an example when using the picture tag also using the fetchpriority = hgih which works when its just on the dom, but my question is without using the preload in the how do we fix this issue? as you don't want to preload the image on every page?

Thank you for your excellent advice! Is LCP computed only for the landing page or for every page a user visits during a session?

Sir this amazing but how to do in WordPress without plugin?

At 27:43: 1. Why is london.jpg still loaded? 2. Why are there only 5 max concurrent requests in flight? I thought Chrome can handle 6 connections to a domain at a time.

Could you please share code example?

Awesome video, how can we optimize wordpress websites?

is it possible to have access to a project you've been working on as a demo? I'd like to follow your steps just to make I can reproduce and see similar results. Thanks

How can I improve the Load delay?

I'm unable to replicate the 'document_ttfb", 'resource_load_delay', 'resource_load_time' in the inspector/Performance - where do you see these features? Thanks.

See the Optimize LCP article for the code that outputs those marks: web.dev/optimize-lcp/

Can we have a source code to practice?

Very useful, Thanks.

It can, especially if you have a lot of content in the prior to the tag. But on most pages it makes very little difference.

Sorry if this was mentioned in the video (I didn't listen to the whole thing). What type on connection do those times target? Is it 4G, 3G?

The thresholds for all the Core Web Vitals metrics are based on UX research, so they target all connection types. See: web.dev/defining-core-web-vitals-thresholds/

يا صديقي العزيز هل هناك ترجمة لمحتوى الفيديو باللغة العربية

As amazing this was, the only issue is that nobody codes in plain HTML anymore where we have absolute control to apply optimisation the web standard way. In Next 12, it's annoying to optimise these things when it still fails in mobile after all the best standard framework practices.

youtube's mobile LCP? 6secs :P

In my eyes everything about LCP is not about the image itself but all the other aspects.. sadly.. And sadly everybody is just talking about the hero image.
