A Little More Detail On Google Snippets
There is a lot of discussion about what exactly a Google snippet is, as Google makes very clear that the term snippet applies solely to the description.
Nevertheless, in general if online marketers talk about the Google snippet they see the snippet synonymous with the search listing, and therefore include the Headline, URL, Description, and other additional information that is shown in the search result.
Besides snippets, you can also create rich snippets. These rich snippets give detailed information to help users with specific queries, and help users recognize when your site is relevant to their search, and may result in more clicks on your page.
