In another improvement to snippets, Google is rolling out list snippets over the next few days. Typically snippets contain a couple lines of text under the search results to give users an idea how relevant a page is in regards to their query. List snippets will differ by reflecting “the structure of the page, rather than just showing two lines of text.”
For example, if a result’s page consists mostly of a structured list, Google will show “a list of three relevant rows or items underneath the result in a bulleted format.” Google also plans to include an approximate count of the total items listed on the page.
In the past week, Google has launched rich snippets for music and +snippets for those using Google+ and the +1 button. Keep an eye out as Google plans to make more improvements to snippets in the future.
