Answer 3

What you have on the screen is called a "snippet". You can't control them directly. Depending on the search query, the search engine substitutes the most relevant (that is, the most relevant to the user's search query) part of the text of your page into the selected part of the snippet. And it doesn't have to be text from decription or og:decription. Working with snippets is important because a good snippet is the most attractive to the user, which means that the user is more likely to go from search to your site.
