Need Expert Suggestion: How Google collect this data?

Hello guys,

Please find the attachment. If you are search with some keyword "kale benefits" in google, it is automatically collecting inner data of some biggest blogs, I have seen some medium blogs data also. How google collect this data from our website. Are we use any scripts? to indicate about our data.

If you have any idea, please reply me.

 

When something of extreme authority has something written on a topic, Google automatically scrapes the content and puts it on the front page, that's as much as I understand about it.

 

Search engines generally tries to understand the 'Intent' of the users through search keywords they use. And tries to give direct solution instead of just listing the URLs to details.
For example, Google THINKS people searching for "US time" really want to know what's current time in different USA timezones, not which websites are listing them. Same case if someone is trying to find meanings, definition of words etc. Google algorithm tries to pick crux of information from authoritative sites like wikepidia, webmd, imdb, dictionary.reference.com, etc. and show them.

 

Same goes to snippets. I believe information like this depends on Google.
They said that if it is worth displaying on SERP then they will pull the information within a certain site and display it on SERP.
