A snippet is a preview of the title and description that Google and other search display for URLs on their results page. A "rich" snippet is therefore an enhanced version of the standard snippet.

Some rich snippets can be incentivized using markup , such as review markup displayed as star ratings next to those URLs in search results.

Rich snippets are structured data.

Structured data can be added to HTML to provide information to search engines during crawling.

This information can then be displayed in SERPs, resulting in an enhanced listing known as a rich snippet.

Rich snippet in SEO

The highlighted excerpts appear in a special position at the top of the search results with a description above the link.

Most of the highlighted sections contain only a summary of information, and the highlighted sections include:

• Information from a third-party website;
• a link to the page;
• the page title;
• The page URL.

The content quoted in the highlighted sections can be a paragraph, a list, a series of steps, or a table. In some searches, Google provides a quick answer or summary with the content snippet from a relevant website.

These highlighted excerpts are more likely to appear when your search is in the form of a question.
