Meta tags are snippets of text placed inside the
<head>section of an HTML document.
They provide metadata about your web page to search engines, browsers, and social media platforms.
While meta tags aren’t visible to users, they play a major role in SEO (Search Engine Optimization), social sharing, and page indexing.
Basic Syntax
