RE: what is meta tag?
Meta elements are tags used in HTML and XHTML documents to provide structured metadata or information about a Web page.Generally they are part of a web page’s head section. You can use <meta> tag to specify keywords related to the web page and later the keywords are used by the search engines while indexing your webpage.
Here I am adding Learn,Skills,Knowledge Share as meta keywords about the webpage.
<!DOCTYPE html> <html> <head> <title>Meta Tags Example</title> <meta name = "keywords" content = "Learn,Skills,Knowledge Share" /> </head> <body> <p>Thank you for visiting my page.</p> </body> </html>
