Search engines are used to find Web sites. They usually catalog sites by following links from page to page (known as spidering or crawling) and saving identification and classification information for each page. One way that search engines catalog pages is by reading the content in each page’s meta elements, which specify information about a document.
Two important attributes of the meta element are name, which identifies the type of meta element, and content, which provides the information search engines use to catalog pages. Figure G.8 introduces the meta element.
