What is a meta description used for?

A meta description is a brief summary or snippet of text that provides a concise description of the content of a webpage. It is typically displayed in search engine results pages (SERPs) below the title tag and URL. The purpose of a meta description is to give users a preview of what they can expect to find on the webpage and entice them to click through to the site. It should accurately reflect the content of the page and be written in a compelling and concise manner. Meta descriptions are important for search engine optimization (SEO) as they can influence click-through rates and improve the visibility of a webpage in search results.
