HTML - Meta Tags

HTML <meta> tag lets us specify metadata, which is additional important information about a document, in a variety of ways. The META elements can be used to include name/value pairs describing properties of the HTML document, such as author, expiry date, a list of keywords, document author etc.

HTML <meta> tag can be used to provide extra information. It's a self-closing element, meaning it doesn't require a closing tag but carries information within its attributes. You can include one or more meta tags in your document based on what information you want to keep in your document but in general, meta tags do not impact the physical appearance of the document so from the appearance point of view, it does not matter if you include them or not.

Examples of Adding Meta Tags

You can add metadata to your web pages by placing <meta> tags inside the header of the document which is represented by <head> tag.

   <meta name="keywords" content="HTML, Meta Tags, Metadata" />

   <title>Meta Tags Example</title>
   <meta name="keywords" content="HTML, Meta Tags, Metadata" />

Document Refreshing

A <meta> tag can be used to specify a duration after which your web page will keep refreshing automatically.

If you want your page keep refreshing after every 5 seconds then use the following syntax.

   <meta http-equiv="refresh" content="5" />
</head>
<body>
   <p>Hello HTML5!</p>
</body>
</html>

Page Redirection

You can use <meta> tag to redirect your page to any other webpage. You can also specify a duration if you want to redirect the page after a certain number of seconds.

Following is an example of redirecting current page to another page after 5 seconds. If you want to redirect page immediately then do not specify content attribute.

<!DOCTYPE html>
<html>
<head>
   <title>Meta Tags Example</title>
   <meta name="keywords" content="HTML, Meta Tags, Metadata" />
   <meta name="description" content="Learning about Meta Tags." />

Setting Author Name

You can set an author name in a web page using meta tag.

<!DOCTYPE html>
<html>
<head>
   <title>Meta Tags Example</title>
   <meta name="keywords" content="HTML, Meta Tags, Metadata" />
   <meta name="description" content="Learning about Meta Tags." />
   <meta name="author" content="Mahnaz Mohtashim" />
</head>
<body>
   <p>Hello HTML5!</p>
</body>
</html>

Specify Character Set

You can use <meta> tag to specify the character set used within the webpage.

By default, Web servers and Web browsers use ISO-8859-1 (Latin1) encoding to process Web pages. Following is an example to set UTF-8 encoding.

<!DOCTYPE html>
<html>
<head>
   <title>Meta Tags Example</title>
   <meta name="keywords" content="HTML, Meta Tags, Metadata" />
   <meta name="description" content="Learning about Meta Tags." />
   <meta name="author" content="Mahnaz Mohtashim" />
   <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
   <p>Hello HTML5!</p>
</body>
</html>

To serve the static page with traditional Chinese characters, the webpage must contain a <meta> tag to set Big5 encoding.

<!DOCTYPE html>
<html>
<head>
   <title>Meta Tags Example</title>
   <meta name="keywords" content="HTML, Meta Tags, Metadata" />
   <meta name="description" content="Learning about Meta Tags." />
   <meta name="author" content="Mahnaz Mohtashim" />
   <meta http-equiv="Content-Type" content="text/html; charset=Big5" />
</head>
<body>
   <p>Hello HTML5!</p>
