Support » Plugin: Yoast SEO » WhatsApp thumbnail doesn’t show when shared on iOS

  • Resolved sgrx



    I’m facing an issue with WhatsApp not showing thumbnails for articles when shared from an iPhone. The thumbnail is visible when shared from WhatsApp on Android.

    For privacy reasons, to not share multiple links here, I’ve shared a link to to a Google doc showing the 2 links where I’m facing the issue, along with 2 articles where I was able to fix the issue in the past. The workaround does not work anymore.

    Workaround I applied on past articles:

    Your recommendations here say that WhatsApp uses the last image in the set. Previously the og:image:alt tag was the last one, so as a permutation I tried removing that, which worked. Instead of using an existing image in the media gallery (which had some alt text), I re-uploaded the image without any alt text in the Facebook image area of the post. This worked and the thumbnail started showing up on iPhone’s WhatsApp for 80% of the previous articles. I did this in first week of Feb. Have shared images in the doc (second page) showing the articles where this worked.

    I tried the following so far, unsucessfully:

    • upload a smaller size image. There are some threads on the web saying the image size should be less than 300 KB, contrary to your recommendation where it appears to accept enormous images in terms of file size and dimensions
    • upload a cropped, square image (1:1). This did not work
    • Remove website caching and disable Cloudflare to ascertain a caching/CDN issue. No change

    Some more things I’ve yet to try:
    – Yoast, by default chooses the large size (1024×1024) image size for the Facebook image.
    – Try removing secure url, adding itemprop attribute,

    Any ideas on what could be causing this, and how to fix this what appears to be an iOS-only issue on WhatsApp?

You’ve confirmed that our plugin correctly outputs the image information since it’s working on Android. The best advice I can give you is to contact WhatsApp to find out why it works for Android and not iOS.
