Write good meta descriptions

The meta description is generally used by search engines to show a descriptive snippet of your site to users in search results. Unlike a title, which should be concise, a good meta description can be a couple sentences long. The sentences should accurately summarize a page’s content. They should not be generic, filled with keywords, or contain an entire page’s content. If Google thinks the meta description of your page is relevant, it will often use it as the search result description found below the title.
