Open a new browser window: Use this link syntax to force a new browser window to open the new page in. It's often used when linking off the site; it will insure the current site is not actually clicked off of.

<a href="http://www.yahoo.com"target="_blank">yahoo</a>

Add a "no follow" tag:This the link syntax used to create a no follow tag. This tag tells the search engines you are not "vouching" for this link. The code prevents page rank "leak" from occurring. It is often used in forums, blogs, and for affiliate links.

<a href="http://www.example.com/" rel="nofollow">discount pharmaceuticals</a>

Add a "no index" tag: If you don't want a certain page indexed by the search engines, such as privacy pages, insert this code into the meta tag area.

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