Google announced a feature they’ve been testing for a few weeks, Structured Snippets.
I am pretty much sure, Most of them is not aware of it what is that feature and what is use of it in search results.
Let me tell you what Structured Snippets:
Structured Snippets is a form of knowledge graph that incorporates facts into individual result snippets in Web search results. It looks like this:
Many of you surely wonder how this data works and how Google is extracting it or may be which algorithm they are using to extract the data so here is your answer :
The WebTables research team has been working to extract and understand tabular data on the Web with the intent to surface particularly relevant data to users. Our data is already used in the Research Tool found in Google Docs and Slides; Structured Snippets is the latest collaboration between Google Research and the Web Search team employing that data to seamlessly provide the most relevant information to the user. We use machine learning techniques to distinguish data tables on the Web from uninteresting tables, e.g., tables used for formatting web pages. We also have additional algorithms to determine quality and relevance that we use to display up to four highly ranked facts from those data tables.
Another example of a structured snippet for the query “superman”, this time as it appears on a mobile phone, is shown below:
