Which is the best way to get the knowledge panel schema for my website ?
Google has not been showing the metadata description for a while now. I guess Google is trying to test it on selected domains or something like that. The thing is that Google has too many factors for deciding the ranking of a page and meta description is only one factor. One reason for low ranking could be because of a poorly written meta description or a bad user experience. I am not fully sure, but I am guessing that is the reason Google is doing this. If you have any more info that is related to this, do let me know.
