A meta description is a short description of a web page. The meta description is not visible to the visitor: it is only in the source of the website, but it plays a large role in getting visitors to your site.
Meta descriptions are an indirect ranking factor. A good meta description will not automatically make your website rank higher in Google, as they announced back in 2009. It does, however, have a big effect on your SEO performance.
Google often shows the meta description in the search engine results page (SERP). It's one of the first impressions of your website for searchers.Back
