Meta descriptions are HTML attributes that provide concise summaries of webpages. They commonly appear underneath the blue clickable links in a search engine results page.

The Meta description is the short description of the webpage that is mostly crawled by the crawl.

The meta description is a ~160 character snippet, a tag in HTML, that summarizes a page's content. Search engines show the meta description in search results mostly when the searched for phrase is contained in the description. Optimizing the meta description is a very important aspect of on-page SEO
