A meta description is a brief summary or snippet of text that describes the content of a webpage. This description is embedded within the HTML code of the webpage and is often displayed beneath the clickable title in search engine results pages (SERPs). Meta descriptions serve the purpose of providing users with a preview of the webpage's content, helping them determine its relevance to their search query. Additionally, a well-crafted meta description can influence user click-through rates by compelling users to click on the link. It's an essential element of search engine optimization (SEO) strategies aimed at improving visibility and attracting traffic to web pages.
