原来以为在页面中加了rel="nofollow"，gg就不会去读，其实这种想法是错误的。

如某网站有这样一段代码：<a href="http://www.9enjoy.com/" rel="nofollow">This is a nice site! </a>
gg不会因为有nofollow，就不理会这个链接，而是照样会去索引此页，但是不会因为这种链接而增加www.9enjoy.com这页的PageRank。

下面是Google官方对于rel="nofollow"的解释：
Together with Yahoo! and MSN, Google introduced the "nofollow" HTML microformat a few years ago, and the attribute has been widely adopted. Any link with the rel="nofollow" attribute will not be used to calculate PageRank or determine the relevancy of your pages for a user query.
