The logic intuition and detail of SEO case diagnosis

SEO is not math, and most places have no precision. SEO is closer to the art, many times by the indistinct logic and intuition and experience, and details are very important.

cited two websites that have recently been looked at.

, a friend’s Web site, inexplicably disappeared in search engines. Previously included normal, I do not know from when, web pages less and less, until completely disappeared.

I looked at the website. It was a simple personal website. Logic tells me, commercial website cheats the possibility that is gotten by K often is not small, the likelihood that individual website cheats is very little, without interest drive, do not deserve to do so at all.

another problem is the English website. In google.com search keywords, ranking first in every two or three days to four or five pages between tiaolaitiaoqu. But ranked steady in google.cn. Because it is English station, so in the google.cn ranking meaningless.

The

logic tells me that this is related to the site language or server location. Looked at the site, is pure English, there is no Chinese characters, server in the United states. Check the reverse link of the site, there are a lot of Chinese Web links. Therefore, preliminary judgment, these links have been judged to be suspected of garbage.
