How to Use Meta Robots Tag For SEO?

Meta robots tag example

When it comes to search engine optimization, most website owners only pay attention to rel=nofollow attribute for links. They seem to forget how to use robots meta tag for SEO and to provide specific directives to search engines on which pages should be indexed and which pages should not be indexed.

If your website has lots of pages, it is not necessary that every page on the website has to be indexed by search engines. There are situations when you would want to prevent search engines from indexing a page (or a bunch of pages) on your website. There are situations when you would not want search engines to crawl any link on a specific webpage.

In all these situations, a robots meta tag comes in extremely handy as it can be used to tell search engines not to index a specific page or not to crawl any link on a given page on your website. Think of Robots meta tag as a common directive given to all search engine bots about a specific page on the website which should be treated in a special way.

How to Use the Robots Meta Tag?

Like any <meta> tag it should be placed in the <head> section of an HTML page on your website, before the </head> section. A sample example is given below

Meta robots tag example

This is just a simple example of the usage of Robots meta tag in a webpage. Depending on your requirements, you can modify the content of this meta tag and achieve desired objectives. But before we discuss that, let’s see all the directives which are supported by the robots meta directive.

DirectiveWhat it does
noindexDo not index this page and do not show this page in search results for user queries
nofollowDo not follow any links placed on this page (both internal as well as external links)
noarchiveDo not show a “Cached” link in search results.
nosnippetDo not show a text snippet or video preview in the search results for this page. A static thumbnail (if available) will still be visible.
notranslateDo not offer the translation of this page in search results.
noimageindex Do not index images on this page.
unavailable_after: [RFC-850 date/time]Do not show this page in search results after the specified date/time. The date/time must be specified in the RFC 850 format.

So if you are using the following code in the head section of a webpage, you are actually telling search engines not to index the content of the page and not to show the page in Google search results


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

Similarly, if you are using the following code in the head section of a webpage, you are actually telling search engines not to follow any link (both internal and external links) on that page and not to pass Google pagerank through these links.


<meta name="robots" content="nofollow" />


Note that you can combine multiple directives into a single code and tell multiple things at once. For example, the following code tells search engines not to index the content of the page and at the same time, not to follow any links on the page.


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

Similarly, the following code tells search engines not to index the content of the page but to follow all the links on the page.


<meta name="robots" content="noindex,follow" />

Now depending on the requirements, you can use these directives in the meta robots tag of your website.
