Hi @kuknus,
Thanks for contacting us, my name is Fellyph and I will help today. I saw that we started another thread previously.
About the page experience guide, it is a tool to provide ways to improve your application in general there are items related to the plugin, but also there are items outside of the AMP plugin scope. It passes 27 checks on your website and as we can see the web core vitals are good, but there are a few improvements that can be made.
The list you can see at the bottom of the page, I will try to go one-by-one:
– Font “eicons” needs to use optional for the font-display property, I have a look here and this font is called by elementor, this is outside the amp plugin scope to control it, but you can check on elementor settings if there is a option to change the font-display to optional
– About the data-hero I would check if it is possible to include this property manually but is not critical your LCP is passing as Good.
– Preload AMP runtime is not applicable, as the AMP plugin will automatically preload it if needed.
– Initial server-response, this is the most critical Item, it is taking 3498ms to respond. It is related to the performance from your hosting, you could check if your hosting is using a recent version of PHP and enabling some caching on the server side. But I saw your website is using WP Rocket to mitigate this problem and cache this response, the report is still getting the response without caching.
The wording “poor” needs a better description, I will report to the AMP framework team. It causes confusion. My website passes all web core vitals and also appears the same message.
And please could you share some of the errors you are getting at search console and the pages that are related to them?
