The outer chain is not everything.

Although now a site outside the chain, you can increase your ranking, but, because the chain is now a lot of man-made, so the search algorithm has been changing, excessive outside the chain, but will make you be punished by the search, so please grasp a degree, enough.

If the keyword is likened to a car, the outer chain is the driving force of the car, I have a friend's station (www.920574.cn), early outside the chain added a lot, ranked straight up, of course, the site's user experience is also very high, the game speed is also fast, but when the power is too high, that is, when the rollover, this one degree, In fact, we often say that weight.

Who do you believe most in this world? Family, friends, or yourself? Who do the search engines trust most? users, outside the chain or your site itself? The answer is obvious, you in more times believe in yourself, and search engine is the same, it determines the ranking of a site, more is based on your site itself, Instead of how powerful your outside chain resources are, how high you have access to the user.

Do not trust users, because there is a word in the programming World "never trust user input data", for search engines, the instability of user behavior is far beyond any program and algorithm can describe and imitate the extent, and in more times user behavior can be artificially simulated, For example, some time ago was fired fiery Baidu Click, and a lot of hackers manipulated by the chicken and so on. For me, I prefer to believe that search engines study user behavior for business purposes rather than for the purpose of increasing the user experience. For example, Baidu's data center, a large number of users search data to sell at high prices; Google's AdWords, what do you think it relies on to match the keyword ads exactly? Based on the above point of view, user behavior is not enough to improve the site rankings, then outside the chain?

The foundation of Internet existence is hyperlink, outer chain is a form of hyperlink. Search engine's original algorithm is based on the site's import links to determine the theme of the site, weight, but the quality of the import link is beyond control, so there has been Google's PR value and other technologies. However, the disadvantages of simply importing links to rank are obvious, and the current buzz of linking deals is enough to illustrate this point.

Although this is the case, the import link can still affect the search engine rankings in a big way, but only if the number is huge. But the huge amount of the chain is like a large number of cabbage, although now can eat, but also very fast, so you need to constantly eat, and finally directly lead to eating dehydration. Outside the chain is the same truth, relying on the chain to get a good ranking of the site will inevitably fall into such a vicious circle, is bound to continue to increase the number of chain, until one day outside the chain to increase speed with the weight of the chain of decay speed.
