personal view: Shanghai dragon industry development direction in China is absolutely not healthy, 10 Shanghai dragon basic will be 9 black hat Shanghai dragon, the user truly customer experience is the first Shanghai dragon basic is very difficult to find, because of the low price, quick, many business owners are the black hat Shanghai dragon suddenly, the black hat Shanghai dragon can improve website ranking in a short time by cheating, but in the long run these sites almost can not survive, the search engine will give drop right, or even permanent blacklist, for non-technical business owners, can not see the nature of things, even out the real Shanghai dragon, I take a few sites for everyone to sit down black hat commonly used means of cheating.
3, the article burstkeywords, no matter what the article will appear keywords, this is obviously cheating, the white hat Shanghai dragon will never take the risk.
summary: in fact, the black hat Shanghai dragon are mistake is that they think about keyword density more favorable for ranking, it is not, as long as your picture clear description, keywords appear reasonable position, you are a healthy site, the ranking will be in front of the site, if you do not believe,
