Meta Tag in HTML

The <meta> tag in HTML is a tool for providing metadata about a web document. It is consistently positioned within the <head> element and serves the purpose of specifying crucial information like the character set, page description, keywords, author details, and viewport settings. It’s important to note that metadata supplied by the <meta> tag doesn’t appear on the actual webpage; rather, it plays a significant role in guiding browsers, search engines, and other web services on how to interpret and handle the content. In essence, it acts as a backstage guide for enhancing search engine optimization (SEO), improving user experience, and facilitating the integration of external resources.
