May progress Report - Page Speed Improved and AMP validation

The WA community is so amazing to me. Before I can ask a question, someone already asks for me. In my progress of improve my page speed, I have gone through the following.

• I try to look for the suitable themes. I learned from the community answer, needs to look for responsive theme. But I cannot improve with the new responsive themes.
• Someone highlights generate press in the community but I saw some members said cannot work for him, so I do not try to use the generate press theme.
• I heard some plugins can help, like WP optimizer, Kraken Image Optimizer but the page speed does not improve at all.
• I asked to site support why my page speed is low. The advice is look into my image optimization for improvement, cache and speed can be taking care by the WA server.
• For image optimization, I have tried many times but not success. I test my page speed and look into the insight report, the report told me to compress my images, embed my videos and change my site theme.
• First I replace all my images from my pages one by one, with proper compress and saving in library to ensure the compression is completed successfully before insert to my pages. Page speed for mobile improve a little.
• Second I try to embed video one by one follow the procedure, page speed improve a little but still in red zone.
• Third I replace my embed videos with URL text link only, my page speed increase to yellow zone.
• Fourth is I have to change my theme. On this day I read in page speed question, one member said generate press work well for her. I think I should give generate press a try. Once I replace the theme with generate press, my page speed improve a lot to green zone.
• After a week, Kyle presentation come with all page speed at full points. A perfect page speed to push me work harder. I saw Kyle using EWWW image Optimizer in his presentation videos. I found the plugin but too advance for me to use. Later the page speed test lead me to use WP Imagify.
• Imagify can compress my image in the library more aggressive but take long time. When I install a new image, this Imagify compressing like no ending, I just don't care and continue my work but finally it do complete the compression process for me. WP asks for rating for Imagify, I give three stars only asking them to improve the compress speed.
• Now my page speed is in green zone but still cannot reach 100 desktop and 100 mobile.

At the same time, I am looking for AMP validation which is more difficult than mobility friendly.

• First I was asked to clear Java script by Google Search Console which I read in page source is pointing to emojis image. I add a free plugin called Really Disable Emojis.
• Second I was asked to improve structural data, I re-write my content to emphasize my keyword in each paragraph which is my title.
• Once done, I take live test for my URL in Google Search Console, the error is clear. I requested for re validation.
• The next day I found AMP valid becomes more and more valid, still have one error pointing to emojis because of my website maintenance for few hours with site support. I try new plugin causing my site frozen. Later site support advice me to remove it.

Attached is page speed result and Google Search Console validation result.

I have little knowledge about SEO/Plugin/Theme/Page Speed and many others. But I am happy learning from the community questions and answers, I managed to solve my site issue. Of course quite often, my site freeze or error many times, site support is my fire fighter to save my site.

Thanks you to all community members giving me a lot of good questions and solutions.
