Nofollow Label Concept
Nofollow is the property value of an HTML tag. Its presence provides webmasters with a way to tell the search engine to "do not track links on this page" or "do not track this particular link." The meaning of this label is to tell the search engine that the link is not edited by the author, so this link is not a trust ticket. Nofollow's correct writing is <a href= "URL" rel= "external nofollow" > anchor text </a>,external nofollow is more professional than nofollow, That is, the link is clearly pointed out as an external link, then everyone has been widely used rel= "nofollow" This format, so the search engine also tacitly this style.

You can also write to the META tag description of the current page.

For Google search engine for a page of all export links whether or not the label will be given the weight of the transmission, then added the nofollow tag link will also be given weight, but will not be passed, then the overall weight of the page virtually evaporated part or all.
Method Two is to write "nofollow" on a link on the Web page, for example: <a href= "http://www.xxx.com" rel= "nofollow" >SEO</A> The effect of this writing is the same as the first method of use, except that the first one is for all outgoing connections on the entire page, and the second is for a particular outgoing link.
