Use the homepage featured image to be the image on social cards

Hello,

I apologize for the issue you are facing. Currently, Rank Math does not support dynamically changing the social card image or title based on the latest featured image or post title from the homepage. The social card image and title need to be set manually for each post or page.

However, you can set a default Open Graph Thumbnail for all pages on your website, and if your homepage is set to display your latest posts, you can change the homepage Open Graph thumbnail under Rank Math SEO → Titles & Meta → Homepage → Homepage Thumbnail for Facebook. This will allow you to set a specific image for the homepage that will be used when shared on social media.

If you would like to have different images or titles for individual posts, you will need to configure them in the Rank Math Metabox for each post.

For more detailed guidance, you can refer to the following resources:

• Set Open Graph Image for Homepage Using Rank Math
• Open Graph Meta Tags

If you have any further questions or if this does not address your needs, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.

Hello,

Thank you for your patience.

You can use this filter to dynamically use the featured image set on your homepage as the og:image tag every time it changes on your site:

add_filter( "rank_math/opengraph/facebook/image", function( $attachment_url ) {
    if ( is_front_page() && has_post_thumbnail() ) {
        // Get the featured image URL
        $attachment_url = get_the_post_thumbnail_url(get_option('page_on_front'), 'full');
    }
    return $attachment_url;
});

Here’s a guide to adding the code to the website:
