Page Speed Insights not recognizing optimization

    Hi there!

    I ran the plugin at Aggressive optimization, which two a solid 24 hours cause we have a lot of images and I’m still getting this warning from Google Pagespeed Insights: Serve images in next-gen formats. I didn’t realize there was an Ultra option to begin with and I can’t figure out how to get it to to rerun at the Ultra optimization. I’m assuming this will help?

    Do you have any advice for me?

    Thank you!! ??

    Okay, I figured out how to change them to Ultra and there’s no change to my score.

    Oh wait! It appears it’s actually starting over with the 1,200 files. I’ll let you know in 24 hours if it worked. ??

    Hi @kskelton!

    This is Joseph from Imagify, and I’ll gladly assist you here!

    This is actually not an issue that has to do with the compression level. Sorry I wasn’t able to answer this in time before you went through the trouble to do that!

    Your images do have WebP versions generated. You can check this by adding a .webp to the end of any of your images’ file name and view in your browser. As long as you don’t get a 404, then you know the WebP file exists.

    Given that, this is most likely an issue having to do with Imagify’s “Use <picture> tags” option for displaying WebP images. I checked your homepage, and actually 6 of your images there are displayed in WebP format. It seems the images that are not being displayed in WebP format is because they are CSS background images. Imagify’s “Use <picture> tags” option works by replacing your tags with <picture> tags. Since there are no tags to be replaced when it comes to CSS background images, this option cannot work to serve them in WebP format.

    A quick option to resolve this is to switch to the “Use rewrite rules” option in your Imagify plugin settings page as long as you don’t use a CDN, Cloudflare, or certain cache services like Varnish (as these conflict and may cause image display issues, especially in Safari browsers). This option will work for images displayed as CSS background images.

    It’s worth noting that using the rewrite rules option will result in your HTML code appearing to display the JPG or PNG versions of images, though the rewrite rules work to ensure the WebP images are actually being served to users’ browsers. You can follow this guide for ensuring WebP images are being served: https://imagify.io/documentation/how-to-check-if-webp-image-is-displayed-on-your-site/.

    Please let me know if you have any further questions on this and I’ll be more than happy to assist!

    Best regards,
    Joseph
