PageSpeed Insights

  • When checking the speed of amp pages, I encountered two problems:
    1.

    Preload Largest Contentful Paint image
    1.08 s
    Preload the image used by the LCP element in order to improve your LCP time. Learn more.

    This applies to featured image. I use CDN Akamai.
    2. “Remove duplicate modules in JavaScript bundles” – must of they from cdn.ampproject.org

    `Remove duplicate modules in JavaScript bundles
    1.05 s
    Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

    Can you please add the Image URL in DNS Priority URL(s) using preload from the dropdown at which you are encountering the issue, Follow this

    In regards to “Remove duplicate modules in JavaScript bundles” We checked your issue. This is not an issue with our plugin. This is an issue from google PageSpeed tools authors. This issue is globally present on every site.

    But the featured images are different on each posts ??
    This must be done “on the fly” for each post.
    After all, this problem now exists for every user.

    The site has thousands of featured images. I can’t write all of them manually in head.
    What should I do?

    Plugin Author Ahmed Kaludi

    (@ahmedkaludi)

    Can you please let us know are you bringing images from any CDN? Or directly from the wp library. And are you using any caching plugins or any cache from the server??

    We have the same issue with high LCP from our Featured Images and slow AMP pages overall.

    We use Cloudflare as a CDN and I just installed AMP Cache. We are using the Swift template.

    This is not true, because if you use the AMP Plugin, this issue doesn’t come up when you use the Pagespeed Tool.

    I too use AMP for WP but I’m considering changing back to the AMP Plugin because of these kind of problems with Core Web Vitals

    Yep. Both of them.

    Plugin Author Ahmed Kaludi

    (@ahmedkaludi)

    It is happening because of CDN as images are needed to be fetched from a different domain. if images come from the same domain then it will take less loading time and speed up the performance

    I noticed one important thing.
    Previously, the image was rendered in webp format. Now jpg.
    Something’s not working.
    You can see the noamp post – https://edieta.org/en/quizzes/iq-tests/can-you-score-5-10-in-this-difficult-iq-test The image is rendered as webp. In https://edieta.org/en/quizzes/iq-tests/can-you-score-5-10-in-this-difficult-iq-test?amp as jpg.

    And one more thing. The image itself is 1280*720. But the amp thumbnail is smaller.

    Plugin Author Ahmed Kaludi

    (@ahmedkaludi)

    We observed that on your site, you have JPG image format on NON-AMP pages too. Can you please check it once?
