What is a Robots Meta Tag?

The robots meta tag is an HTML meta tag that instructs search engine crawlers on crawling, indexing, and displaying a webpage on search result pages. For example, the robots meta tag below instructs search engines not to index a webpage.

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

The robots meta tag is inserted in the head tag <head> of the webpage. For example:

<head>
  <meta naam="robots" inhoud="noindex">
</head>

In the codes above:

Meta indicates this a meta element
De name="robots" attribute indicates it is a robots meta tag
De inhoud attribute contains the instruction the blogger has for the search engine
De content="noindex" attribute specifies that the search engine should not index the webpage

When containing multiple attributes, the robots meta tag is separated using a comma, for example:

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

You can also direct the robots meta tag to a specific crawlerbot. For example, if you do not want Googlebot to crawl your site, you will use Googlebot instead of robots. For example:

<meta name="googlebot" content="noindex">

Google only supports de googlebot (text results) and googlebot-news (Google News) user agents and will ignore instructions directed at other user agents.

Difference Between the Robots Meta Tag, robots.txt File, and the X-Robots-Tag

The robots meta tag is different from the robots.txt file. The robots.txt file tells search engine crawlers how to crawl the entire site, while the robots meta tag and X-Robots-tag tell search engines how to crawl a specific webpage.

In this case, the robots meta tag is usually used for HTML pages while the X-Robots-Tag is used for non-HTML properties like PDF files, videos, and images.

Why Are Robots Meta Tags Important?

The meta robots tag lets bloggers control how search engine crawlers interact with their content and display it on search results pages. This is helpful for bloggers who want to prevent search engines from displaying unwanted or sensitive content on their search results pages.

For instance, the robot meta tag can contain directives like noindex, nosnippet, en nofollow.

Noindex tells search engines not to index the webpage and display it in search results
Nosnippet tells search engines not to display rich snippets for the webpage
Nofollow tells search engines not to follow the links on the webpage

<meta name="robots" content="noarchive">

<meta name="robots" content="max-snippet:15">

8 Max-image-preview: [setting]
