Using a Silent Meta Description with Search Engines
Search Engines automatically highlight display snippets of matched text from web page content to the search user to attract their attention and their clicks.
In many cases this text may occur in the body and not in the meta description or title. For specific cases it might be wise to have no meta description at all. When competing for adjectives such as best, good, top – a silent description allows user generated content to bubble up to the search engine result page.
