Robots Meta

About the Robots <META> tag

In a nutshell

You can use a special HTML <META> tag to tell robots not to index the content of a page, and/or not scan it for links to follow.

For example:

<html>
<head>
<title>...</title>
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
</head>

the NOFOLLOW directive only applies to links on this page. It’s entirely likely that a robot might find the same links on some other page without a NOFOLLOW (perhaps on some other site), and so still arrives at your undesired page.

Don’t confuse this NOFOLLOW with the rel=”nofollow” link attribute.

The “NAME” attribute must be “ROBOTS”.

Valid values for the “CONTENT” attribute are: “INDEX“, “NOINDEX“, “FOLLOW“, “NOFOLLOW“. Multiple comma-separated values are allowed, but obviously only some combinations make sense. If there is no robots <META> tag, the default is INDEX,FOLLOW“, so there’s no need to spell that out. That leaves:

<META NAME="ROBOTS" CONTENT="NOINDEX, FOLLOW">
<META NAME="ROBOTS" CONTENT="INDEX, NOFOLLOW">
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
