Rich snippets are additional pieces of information that Google uses to to enhance a searcher’s understanding of the value of that page.
Review Rich Snippets are an average of the combined rating scores from reviewers. They appear in organic Google Search results either under the search result itself or in the Google Knowledge Cards. When Google finds valid reviews or ratings markup, they show a rich snippet that includes a star rating (on a scale of 1 to 5) alongside other summary info. This makes your reviews visible in search results.
With Rich Snippets you can:
- Improve your visibility on SERPs
- Increase your webpage's click-through-rates
- Increase customer trust in your organic search results
