What is the importance of meta tag?

Hello,
What is the importance of meta tag?

Meta tags are part of the HTML tags that describe your page content to search engines and website visitors. The Meta tags appear only in the page's code and anyone can check them via source code (Ctrl+U).

Meta Tags are important because they can have a big impact on your click-through-rate. This is because most search engines will pull your Title Tag and Meta Description to form the snippet of data when your pages are listed in organic search results.

Meta tags are important since they help contribute to user experience and are an important part of building a website.

A meta tag is a tag (that is, a coding statement) in the Hypertext Markup Language (HTML) that describes some aspect of the contents of a Web page. There are many meta tags and html-tags and obviously they don't all influence the search result.
