The Robots META tag is used to tell a web robot whether a Web page can be indexed and to track links on its pages. The tag element already occupies an increasingly important position. Also, it applies to not having control over the robots.txt files in the top-level server directory, and some search engines are now fully compliant with the robots Meta Tag, such as Inktomi. The format of the Robots meta tag: The robots meta tag is placed in the header area (head area) of the background HTML source code in a format similar to the following: (uppercase and lowercase)
<html>
<head>
<meta name= "ROBOTS" content= "Noindex,nofollow"
<meta name= "DESCRIPTION" this PAGE ... ">
<title>...</title>
</head>
<body>
...
Robot meta tag option:
There are four instructions available in a single robots meta tag: INDEX, NOINDEX, follow, and NOFOLLOW, separated by ",". Where:
Index directive: Indicates that robot can index this page;
Follow directive: Indicates that robot can track links to this page;
noindex directive: To deny Robot index this page, but to track links on the page;
NOFOLLOW directive: Reject robot Tracking link on this page, but can index this page.

<meta name= "Robots" content= "Index,follow"
<meta name= "Robots" content= "Noindex,follow"
<meta name= "Robots" content= "Index,nofollow"
<meta name= "Robots" content= "Noindex,nofollow"
