Hi Brittany,
While it is not essential to have meta descriptions for each page, especially if they are not indexed by Google, there can still be some benefit to having meta descriptions for pages people are linking to. Users can see the meta description if the page shows up during a search query, and sites with strong meta descriptions tend to come across as more professional. There is always a chance the page can show up in other search engines and directories, so you won’t want to worry about random text showing up. There is no real ranking benefit to meta descriptions, but Google does indicate whether meta descriptions are too long, too short, or too similar in Webmaster Tools, so it would seem Google would consider proper meta descriptions to be of at least some value.
