may be senior webmaster know rel= "nofollow" meaning, but I still want to write out. According to my Exchange http://www.aliyun.com/zixun/aggregation/8495.html "> Links experience, there have been some exchange of links between the" thief "molecule! List the following:
1, to link the links into the JS code inside;
2, to link into the embedded page links;
......
Anyway the trick is endless. As I focus on today, rel= "nofollow", his intention is to prevent search engines to search those blog sites spam, do not want to be indexed comments. Because a lot of people in order to get to their own site to import links, so a lot in the message board, BBS posts, which for search engine is a spam link. If the station owner sets such a limit, the search engine knows not to index those links.
Because it has to prevent the search engine to search the attributes, so many webmaster "bad" adoption, which links the most widely used parts.
For example, an ordinary friendship link if this is:
<a href=http://www.365xxg.cn>365 fantasy Novel Network </a>
Then add the label to this:
<a href=http://www.365xxg.cn rel= "nofollow" >365 fantasy novel Network </a>
The general colleagues, you think, such links still have meaning?
No, there is no point to prevent search engines to search, to crawl, this is simply a thief behavior, shameless to pick the fruit of others.
