Recently, due to Baidu frequently qj, in the domestic SEO industry has caused a very large response, especially the "left-carnitine" has been a few artificial intervention Baidu, several times again. In fact, "left-carnitine" used is the station Group + sprocket Black Hat technology, sprocket strategy has long been used by foreign SEO people, just because of the recent "left-carnitine" has aroused people's concern, so the sprocket will be in the domestic so fire; In addition to their own main station, the other is a third-party blog or Web2.0 website But to China, because the Chinese people's wisdom, we carry forward, sprocket station is also set up their own, became a station group + sprocket strategy.

I saw a variety of chain models on foreign websites, but basically did not break out of the following several models, are in the following several sprocket model changes, evolution.

The first sprocket model:

This sprocket model is the most basic, money site is our own main station, outside the sprocket station are the use of third-party blogs, the advantages of this model is more cost-effective, sprocket station number can be unlimited expansion; The disadvantage of this model is that the model is simple, easy to be found by search engines, because it is the use of other people's website, So ownership is not in itself, 8630.html "> Sometimes the blog is easily deleted, causing the sprocket instability."

The second sprocket model:

The second chain model on the first model has a certain change in the outside of a ring sprocket station joined some Web2.0 Web site, so that the sprocket looks more natural, but also to the station group to bring a certain weight.

The third type of sprocket model:

The third model is more complicated than the second, in fact, not much different from the second, but the sprocket station and the main station submitted to a different bookmark site, because the bookmark site can improve the weight of the site. This makes the Sprocket station group more complex, so that the station group more natural, reduce the chance of discovering the sprocket by search engines.

Fourth Sprocket Model:

The fourth model is small sprocket composed of large sprocket, each sprocket chain to the main station, in fact, the constant changes in the chain, the most important one is to keep our sprocket complex, reduce the search engine to find the probability of sprocket.

Fifth Sprocket Model:

Finally, the sprocket model is constructed according to Hamilton Path, which belongs to the NP complete problem. In fact, is an irregular link, that is, a small model of the Internet, so for the search engine is to judge the probability of the station group is almost zero.

The last model, there may be a lot of people want to follow this model to build their own station group, I will be in the next article in detail this model, introduce the meaning of different color button representatives. I hope you will continue to pay attention to the studio (www.passseo.com)
