    Hi,

    I have 3 issues with AMP pages:
    1. Duplicate JS – All are AMP JS – How do I prevent these scripts from loading?
    2. Unused JS – Again all are AMP JS – Should I load them in footer?
    3. LCP – Image issue:
    Hush 2016
    I have preloaded the image, but still is not loading fast. Do I have to cache the image separately in AMP Cache and load it from there?

    Regards

    The page I need help with: [log in to see the link]

  • With regards the duplicate JS from inspecting your site these these seem to be ad related. As this is more specific to the AMP Framework feel free to open a GitHub issue on the AMP repository for further insights.

    In relation to unused JavaScript there was a discussion in the AMP GitHub repository. From there you’ll find that there is work being done to reduce the amount of “unused JavaScript” from AMP documents. There is also an open GitHub issue on the Lighthouse repository. This isn’t something we can address on the plugin side unfortunately. From one check on your site the unused JavaScript is also in relation to ads, which may be understandable if ads were not served at some point.

    Note that I don’t see any issues with the image from my side, it’s served as a webp image taking us 54ms.

    Hi James,

    Thanks for the revert. Will follow it on Github.

    Note that I don’t see any issues with the image from my side, it’s served as a webp image taking us 54ms.

    Sorry for the confusion, I meant on PageSpeed – https://www.awesomescreenshot.com/image/6323556?key=94fdf4fb81e9df00e7a96eec2fc3a99a

    I don’t see anything in particular from your provided PageSpeed Insights screenshot of concern. Your site performs very well when performing a check on web.dev, which uses the same Lighthouse technology as PageSpeed Insights.

    You may find better support regarding the different metrics on your site when using the Search Central Help Community.
