Hello @voodoochill

It’s warning so you can ignore it, It is recommended to use at least one image with 1200px width, the cover images are best suited for this kind of images.

Ref : https://developers.google.com/search/docs/data-types/article#amp

If it adding large image mess with your site layout add a default image only in Structured data.

If you are using any SEO plugin check if you can add default images for all posts with filters for example Yoast SEO provide wpseo_schema_article filter.

Hello @voodoochill,

Sorry I do not understand what are cover images.

You can add a cover image for a blog post with Cover Block as shown here in the screenshot

Or you can choose a featured image as shown in this screenshot.

Let me explain how you can use wpseo_schema_article

first, upload a generic image that represents your site
goto Dashboard -> Media-> Add New
Now open the image and check copy it’s ID as shown in this screenshot

Use the copied ID and replace the below code with 1234, now copy the whole code add it in your themes functions.php or in custom plguin.

add_filter( 'wpseo_schema_article', 'example_change_article' );
add_filter( 'wpseo_schema_webpage', 'example_change_article' );

/**
 * Adds images to Article Schema data.
 *
 * @param array $data Schema.org Article data array.
 *
 * @return array Schema.org Article data array.
 */
function example_change_article( $data ) {
	// This is the attachment ID for our image.
	$attachment_id = 1234;

	// We're going to create a graph piece for our image. Every graph piece always needs a Schema ID, so it can
	// be referenced by other graph pieces, best practice is to base that on the canonical adding an ID that's
	// always going to be unique.
	$schema_id     = YoastSEO()->meta->for_current_page()->canonical . '#/schema/image/' . $attachment_id;
	$data['image'] = YoastSEO()->helpers->schema->image->generate_from_attachment_id( $schema_id, $attachment_id );
	return $data;
}

This will code will add an default image in structured data for every post.

I will also recommend contacting Yoast SEO support as the sturctured data is generate from Yost SEO plugin.

Are you saying I can make all my featured images 1200 x 1200. I can maybe do that as I do not display them on the article, they are only ever used as thumbnails.

Yes, but please check with your SEO plugin support to make sure those are included in the schema

It seems a bit silly to use such a large image for a thumbnail, but who am I to argue with Google?

Images will be used for displaying Google Search result cards as shown in this screenshot.

For the pages without featured images I am still a bit confused. Am I correct in saying that the default image in structured data will only apply when there is no actual feature posts specified?

No, the code snippet I provided will add default images to all the Posts and Pages despite having featured images. I will recommend contacting Yoast SEO support regarding the same as I can not advise you further as your site is using their plugin to generate structured data.

So I don’t understand how a default image that shows on all pages fits the criteria of directly belonging to an article.

Yes this is correct we are just hacking our way to add image I think Yoast People will be best to advise you for SEO related stuff

I will mark this topic as resolved, As your issue is not related to the AMP plugin. Feel free to open a new support topic if you require any further assistance.
