Hello @mohanadas,
Thanks for using the Yoast SEO plugin. Can you let me know how images are added to the posts? Yoast SEO analyzes the default WordPress content areas like the title, URL, and the main content box (WordPress editor). If you are adding your content through other plugins or theme content boxes (as most page builders do), Yoast SEO may not be able to detect it by default. Currently, we are compatible with the Elementor page builder. The?Yoast SEO Elementor integration?is free to use for everyone; no premium or add-on is required for core functionality.
Although our plugin does not detect your content and shows an incorrect analysis report, this does not affect how search engines crawl and analyze your site. Search engines process the front end of your site and will detect your content.
