SEO that thing how to avoid to do an unqualified seoer

Yesterday accidentally saw Baidu Webmaster forum Lee answered a few questions, of course, some well-known reasons, he did not give a very clear answer, we all know. Most of his answers are fine, but there are a few questions that I need to experiment with to verify the observations.

1, the text link URL address, Baidu will find that he is a URL address and through the address to the corresponding URL to crawl.

If Baidu will crawl the text of the link address, then according to the regular to judge the URL, then I can through the text URL to let Baidu crawl some I do not want users to see the page, there are some in the obvious can not find the link. According to the user experience point of view, as well as Baidu itself that hypertext computing method will not set up, this if the link for the text URL address will go to the corresponding crawl is very questionable.

2, we should transfer the weight of the link, the only criterion is: this link whether the user or the other site really recommend your site, this recommendation, whether the user has value.

Do SEO for a long time friends should know, Baidu official position is to support the nofollow label, then say whether the link transfer weight value self-love and this link for the user is valuable this estimate can only be calculated according to the pertinence. If the chain of words I believe can be judged by this way, so here's a rhetorical question I ask Lee station links plus nofollow How to interpret the link is valuable to users?

3, for the domain name changed hands, we have a set of judgment mechanism, the normal domain name changed hands, domain name will be treated as a new domain name, regardless of whether there has been cheating before, the former bill.

This is quite far-fetched, the domain name of the normal turnover of this Baidu can not judge, the domain name registrars will not provide data to Baidu's official this judgment can not calculate. The second is based on the search engine sandbox principle, then the behavior of cheating will be left a record, then the domain name from the new fight out of this time will be long and long.
