I noticed that every post (but not pages) on my website has more or less three sections of meta tags related to images:
- a proper meta set of og:image, og:height, og:width for the featured image of the post,
- an empty set of og:image, og:height, og:width,
- and a proper meta sets for either photos or videos in the post.
I wonder what might be the reason for the empty values to appear in the second position? And whether they have any adverse effect?
I checked the debug option, but cannot see any additional info coming from that.
