We divided the article into 5 levels, the popularity of the original article level of 5, the general original article level of 4, highly pseudo original Grade 3, and so on. Search engine will correspond to the article into the corresponding position, the popularity of the original article to give the highest weight, which will give you the page of this article to bring rankings (of course, but also through some simple optimization, such as to do around a word, etc.).

The whole process is so simple, then the spider can come to your page.

Reply also graded and weight, so why many people like to rob the building, first and to third place the signature anchor text weight is the highest. Is there no weight on the back of the signature? If this article replies more than 100, there are 5 reply pages, the first page of the signature weight is the highest, the second one slightly lower, and so on. If this article gets 4 PR value, then the first page of the first name of the reply weight is at least 2! Equivalent to a one-way friend chain! The last one on the first page is at least 1. If this article replies more than 500,PR value to 5, the first page of the first name of the reply weight is at least 3, the first page the last one of the weight of at least 2. At the same time, the higher the weight of the previous pages. The second page can get 5 PR value! If this article replies more than 1000,PR value to 7, then the first 500 reply signatures benefit the most! The more people you reply to, the more your signature is, the higher your signature PR value is!
