HTML Meta Tags

17. HTML Meta Tags

HTML <meta> tags provide metadata about the HTML document, such as description, keywords, author, and more. Meta tags are placed inside the <head> section of an HTML document and are primarily used for SEO and improving web accessibility.

What Are Meta Tags?

Meta tags are elements that provide information about a web page to search engines, browsers, and other services. They help describe the content of a webpage and influence search engine rankings, social media previews, and more.

Common Meta Tags

Here are some of the most commonly used meta tags in HTML:

1. Meta Description

The <meta name="description"> tag provides a brief summary of the page content. Search engines often display this description in search results, so it's crucial to make it concise and relevant.


<meta name="description" content="Learn HTML meta tags and how to use them for SEO and web development.">

2. Meta Keywords

The <meta name="keywords"> tag contains a list of keywords related to the page's content. Although it's no longer used by most modern search engines, it can still be beneficial for some niche search engines.


<meta name="keywords" content="HTML, Meta Tags, SEO, Web Development">

3. Meta Author

The <meta name="author"> tag specifies the author of the document.


<meta name="author" content="John Doe">

4. Viewport Meta Tag

The <meta name="viewport"> tag is crucial for responsive web design. It ensures that your page scales correctly on mobile devices and that content fits the screen size.


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

5. Charset Meta Tag

The <meta charset="UTF-8"> tag specifies the character encoding for the document. UTF-8 is the most widely used character set and supports almost every character in all languages.

6. Robots Meta Tag

The <meta name="robots"> tag is used to control search engine crawling and indexing. You can instruct search engines not to index a page or follow links on a page.


<meta name="robots" content="noindex, nofollow">

Common values include:

noindex: Prevents search engines from indexing the page.
nofollow: Prevents search engines from following links on the page.
index: Allows search engines to index the page (default behavior).
follow: Allows search engines to follow links on the page (default behavior).

Other Meta Tags

There are several other meta tags that serve specific purposes, such as:

Social Media Meta Tags: These include Open Graph and Twitter Card meta tags to control how your content appears when shared on social media platforms (e.g., Facebook, Twitter).
Content-Type: Specifies the media type and character encoding of the document.
Refresh: Automatically refreshes the page or redirects the user after a certain period.
