These days in the QQ group to know a few better optimization aspects of the station, feeling to see the article is simply a enjoyment. Like many of the webmaster who are reading this article, I am about to graduate, but I haven't graduated yet. Since the decision has been decided to work in the network after graduation, so at present is the experience of optimization and promotion of the evil. Hope to meet more friends in the industry, we communicate together. I always thought that everyone has their own strengths, of course, there are their own shortcomings, through a wide range of exchanges, we can achieve a total win.

I have just read an article:

The following refers to the content: honesty, especially as webmaster, do not be scolded

/html/4/2/20070316/37702.html

Just the day before yesterday saw a similar article, now sent out, aiming to deepen their understanding of their degree and for your reference.

I've seen this code before and I don't know what it means. It turns out that Nofollow was a new label, led by Google, a year or so ago, aimed at minimizing the impact of junk links on search engines.

Matt Cutts said 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. The search engine sees this tag and may reduce or completely cancel the voting weight of the link. This tag is usually used in blog comments or forum posts because these are the places where the most junk links appear. Now mainstream blogs and forum software automatically add this tag to the comments and posts link. Another effect is that if you sell ads on the website, you can use this tag. Because the original intention of buying and selling web ads should be traffic, not PR value or try to influence search engine rankings. Adding this tag does not affect traffic at all, but it may reduce the impact on search engine rankings.

Although GOOGLE,YAHOO,MSN expressed support for the label, but did not necessarily say that the weight of these connections down to 0, other search engines such as Baidu may be less affected by this.

Quote Master words: Not for SEO and SEO is doing a good job of SEO, the key is to do the content well, the appropriate optimization.
