has a lot of people ask me questions, for example, "words in general how many times can appear in the article, or keyword density is how to plan?" the most basic problem, I think it is unbelievable, we have to think, now the webmaster is really understand the basic establishment of law, or that is the real good optimization basis? In other words, a few stationmaster now known as optimization in the company, known as the so-called "technical personnel" (Ps: is the first to correct, for the optimization of personnel, do good technical staff, really no pun intended). They just know the results of handling the labor of others, then simply replace the link to their own things, may feel very glorious, or to make some easy to do the chain of garbage Let the search engine, overwhelmed, for such people, I believe that most are excluded (Ps: I said so much, in fact, is really think we can build a harmonious environment for the search engine. ).
