自从看了国平对nofollow的文章后,Yourself is a basic idea of nofollow。Personal understanding,Nofollow is more from the station to guide the spiders to crawl。Himself on the company's Web site a large number of applications the nofollow tag,Under a small summary。

新站在优化好之前一直是用robots屏蔽掉了所有的搜索引擎蜘蛛,But once basic optimization,Began to let spiders crawl。This means that,In Spider opening crawl when the new station,Many pages are nofollow。UseWeb Log Explorer cracked versionObserve a month of Web log,Found be nofollow out of starting a page,From beginning to end is not Google's spiders,Of course are not indexed by Google。
