Snippet term explained

When searching in any search engine the results are shown in the form of titles, descriptions and some other information with link to the found resource.

Description of the resource in the SERP is called a snippet and may include not only link to site, but also depending on the type resource contain additional information:

• additional links from the website; 
• the creation date of the post on the forum and number of respondents. 
• preview of vide and its duration; 
• description from DMOZ; 
• the physical address of the company.

In recent times search engines tend to place the control buttons in search results and sending comments.

Extended snippet in the search results will give more clicks than uninformative.
