What is a meta description, and does Google use it in search results?
What a meta description is, when Google shows it, and how to write one
A meta description is the <meta name="description"> tag in a page's HTML that summarizes what the page is about, and Google sometimes uses it as the snippet under a search result. Google builds most snippets automatically from the page's own content and uses the meta description only when it describes the page more accurately than the content does. Site owners cannot set the snippet by hand, so a good description raises the odds of being shown rather than guaranteeing it.
What it is and where it shows
A meta description is a tag in the head of a page, written as . Visitors never see it on the page itself. It matters in search results, where Google may use it as the snippet, the short summary under the page title.
Google does not promise to show it. Its documentation says snippets are created automatically, mainly from the page's content, and that the meta description is used when it describes the page more accurately than that content would. Because snippets are built around the search that was typed, the same page can show different snippets for different queries. Google also says site owners cannot change a snippet by hand.
Length
Google sets no length limit on the tag. Snippets are cut off in search results as needed, usually to fit the width of the device. If you want to cap how long a snippet can be, the max-snippet:[number] robots meta tag does that. The nosnippet meta tag stops a snippet being shown at all, and the data-nosnippet attribute keeps a specific part of a page out of it.
Writing a good one
Write a different description for every page. Google's guide says identical or similar descriptions across a site are not helpful, and suggests a site-level description for the homepage and other aggregate pages with page-level descriptions everywhere else. If there isn't time to write them all, start with the homepage and the most popular pages.
The description does not need to be sentences. It is a good place for facts scattered across the page: the author and publication date of an article, or the price, age and manufacturer of a product. Google's examples contrast a bare keyword list with a description of what a shop sells plus its hours and location, and a one-word description with a specific one that names features, colors and a shipping offer.
At scale
Sites built on large databases cannot write each description by hand. Google calls generating them programmatically appropriate and encouraged there, as long as the results are readable and varied. Descriptions that are long lists of keywords are less likely to be shown, because they don't tell a searcher what the page contains. On Wix, WordPress, Blogger and similar systems, Google points to the CMS's search settings rather than editing the HTML.

Questions
Will Google always use my meta description?
No. Google builds snippets mainly from page content and uses the meta description only when it describes the page more accurately. The snippet can also change depending on the search.
How long should a meta description be?
Google sets no limit on the tag itself. Snippets are truncated in results as needed, mostly to fit the device width.
Can I stop Google from showing a snippet?
Yes. The nosnippet meta tag blocks snippets for a page, max-snippet:[number] limits their length, and the data-nosnippet attribute hides specific parts of a page from the snippet.
