[Content] Page Descriptions [Action] 
Most search services display some text from the matched pages, allowing searchers to learn something about the contents before they click on the link. This can come from one or more of several sources: the contents of the Meta Description tag, written by the page creator matching lines: sentences which contain the search terms first useful text: avoiding navigation information by locating the first header tag and extracting text starting there summary text: uses a special formula designed to find the sentences which best summarize the page content top text: text from the top of the page The first three options are the best: search engines which attempt to find the "best" sentences usually fail; those which extract the first text from the page often display useless navigation information or even JavaScript or CSS.
