Rich snippets are the additional bits of information that are displayed under search results. Essentially, rich snippets are html tags that help search engines better understand the content of the page. This provides a better search experience for users and helps them find relevant information faster.
What kind of rich snippets are there?
How will you benefit?
While not necessary, they make your listing stand out and help you get noticed! Google doesn’t promise to use your markup code for the rich snippets. It also doesn’t guarantee that your page ranking in search results will be higher because of the rich snippets. But, on the other side, Google tends to reward pages that provide relevant content that users click and share. Obviously getting noticed is a first step to increasing click-through rate which in turn should lead to increasing the page rank.
