It is common for search engines and directories to provide a snippet of information next to each and every listing in order to bring about some context to the title. Highly regarded and successful directories generally prefer the description to simply provide a brief description of the nature of the website rather than take a more promotional stance. Search engines have been known to commonly utilize a description from a well-trusted directory, make use of the meta description tag or simply try and fetch a description from the actual contents of the page.
