HTML Meta Tags

 

Meta tags in HTML are special elements placed within the <head> section of a webpage that provide metadata, or information about the webpage itself. This metadata is not visible to users on the webpage, but it plays a critical role in how browsers, search engines, and social media platforms interpret, display, and interact with your site. .

Common Uses of Meta Tags

  1. Search Engine Optimization (SEO):
    Meta tags help search engines understand the content of your page, influencing how your site appears in search results. Properly written meta tags can improve your site’s visibility and ranking on search engines like Google.
  2. Browser Behavior:
    Some meta tags control how browsers behave when loading your page. For example, you can set encoding formats or tell browsers how to adjust the page layout on different devices (such as desktops or mobile phones).
  3. Social Media Sharing:
    When users share your webpage on social media, meta tags can determine what content gets displayed in previews, such as the title, description, and image.
 

 

Basic Structure of Meta Tags

<!DOCTYPE html>
<html lang=”en”>
<head>
    <meta charset=”UTF-8″>
    <meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
    <meta name=”description” content=”Meta Tags”>
    <meta name=”keywords” content=”HTML, CSS, JavaScript, tutorial”>
    <meta name=”author” content=”Your Name”>
    <title>Page Title</title>
</head>
<body>
    <h1>Hello, World!</h1>
</body>
</html>

 

Common Meta Tags

1. Character Set: Defines the character encoding for the HTML document.

<meta charset=”UTF-8″>

 

2. Viewport: Provides instructions on how to control the page’s dimensions and scaling. This is useful in making the responsive websites.

<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>

  • width=device-width: Sets the width of the viewport to match the width of the device’s screen.
  • initial-scale=1.0: Sets the initial zoom level when the page is loaded (1.0 means no zoom).



    3. Description: Gives a brief description of the page. This description often appears in search engine results.


<meta name=”description” content=”A brief description of the page’s content”>

 

4. Keywords: Lists keywords relevant to the page’s content. Though not as important for SEO as they once were, they can still be useful.

<meta name=”keywords” content=”HTML, CSS, JavaScript, tutorial”>

 

5. Author: Specifies the author of the HTML document.

<meta name=”author” content=”Your Name”>

 

Advanced Meta Tags

1. Refresh: Automatically refreshes the page after a specified number of seconds.

<meta http-equiv=”refresh” content=”30″>

The page will be refreshed after 30 seconds

 

2. Robots: Instructs web crawlers on how to index the page.

<meta name=”robots” content=”index, follow”>

index / noindex: 

  • index: Tells the robot to index the page, making it searchable.
  • noindex: Tells the robot not to index the page.

follow / nofollow:

  • follow: Tells the robot to follow the links on the page.
  • nofollow: Tells the robot not to follow the links on the page.

 

3. Open Graph: Protocol developed by Facebook, it allows web developers to control how content from their website is displayed when shared on social media platforms like Facebook, LinkedIn, Twitter, and others.

<meta property=”og:title” content=”Example Title” /> 
<meta property=”og:description” content=”This is an example description of the page.” />
<meta property=”og:image” content=”http://example.com/image.jpg” />
<meta property=”og:url” content=”http://example.com/page.html” /> 
<meta property=”og:type” content=”website” /> 
<meta property=”og:locale” content=”en_US” /> 
<meta property=”og:site_name” content=”Example Site” />
