Meta Tags are snippets of HTML code that contain information about the content of a web page. They do not appear on the web page itself but exist in the code, providing search engines with crucial details about the page's content, such as keywords used, authorship, or character encoding.
While not all Meta Tags directly impact search engine rankings, they play a significant role in helping search engines understand a page's content and how it should be presented to users. For example, the "description" Meta Tag can provide the text for search engine result descriptions (SERPs).
