no image found Yoast SEO

Hello,

We have installed Yoast SEO and it shows the following message (check the attachment):

“No image found on this page. Add some!”

I think that WPbakery is fully compatible with Yoast SEO. Why is it displaying this message?

Do i need to do anything else?

Note: I would like to leave this topic open for future questions. We wanted to improve the SEO from our Client Site and this will be the first time for us.

Thanks for yout help.
Best Regards.
