Set the nofollow tag forum, it is clear that spiders are not allowed to crawl, this time webmaster left posts outside the chain and http://www.aliyun.com/zixun/aggregation/30698.html "> personality signature outside the chain is invalid, Because spiders do not crawl words inside the page how to include, it is not possible to increase the number of your outside chain. Even though these forums allow you to add a chain, all work is done in vain because of the label.

2, low weight of the forum is not suitable for the addition of the chain

In general, the high weight of the site pr>4 above the forum is the main webmaster to add the chain, because the high weight of the site not only spider crawling frequent, Second harvest phenomenon, more key is included in the page will not be deleted, high weight site, Baidu likes. However, if the pr<4 below the site that in the quality of a big buckle, and Baidu included after the possibility of deletion is not larger.
