Yoast SEO shows " No images appear on this page " for a particular page which contains images in my website. I already updated Yoast SEO plugin, but there is no change. How can I solve this problem?
From my experience, Yoast only seems to pick up images that are either on the theme's Featured Image function or in the default post editor content itself.
You haven't included a link to your website. My own website relies heavily on Advanced Custom Fields and PHP functions/shortcodes that produce images, and Yoast doesn't always pick these up.
Presumably, because they're not rendered on WP-admin therefore Yoast doesn't see them.
