I focus on one article describes about the outer chain network optimization in the role and outside the chain of some basic common sense, then a good achievement outside the chain in the end is how he scores in the network optimization it? As a webmaster you how it is to truly implement network optimization to it? With these questions, we enter today's lesson --- how to do some of the high weight of the chain, the chain will determine the quality of our web site in the search engine weight, the weight of which is to increase the site's most direct way, It is also the site Baidu search engine keywords entered both before twenty the necessary conditions. The role of the chain is self-evident, presumably webmasters are aware it is in the importance of keyword ranking among. About the role of the chain, I will not trespass with big chapter to pay more to say, we all know very well. Since this year, Baidu launched a green dill algorithm after dealing a serious blow outside the chain, garbage outside the chain. The algorithm is Baidu search engine algorithm is an anti-cheat, the purpose is to purify the Internet environment, to promote natural link. The advent of green dill algorithm also increased the threshold for site optimization, relies entirely on the way to the outer chain accumulation keyword ranking make up is gone. Webmaster personnel engaged in more than one year, there will be such a complaint, "the role of the chain is now getting smaller and smaller," in fact not the case, outside the chain in keyword ranking which still serves as an important role, but where the outer specifically refers to the natural chain outside the chain, the so-called natural connection, by definition, is a naturally occurring link, the user will go to click on the link (not including deceptive connection), also called extended to meet user needs. Among the search engines outside the chain, as is the role of the site voting, and now the Baidu search engine on the first page of each keyword and the second page as a large platform, only the site into the top 20 in order to enjoy Baidu Click to calculate law rights, and promote the website keyword ranking in the top 20 fast the most effective way is outside the chain. So, each site needs to be done in the early outside the chain, and it must be natural connection, garbage or traded outside the chain connection is not only not improve website ranking, but also seriously affect the keyword ranking. www.xinsiwei.net.cn natural link production methods: 1, Links: Links are voting sites and between sites, Baidu did not include it among the rubbish outside the chain, but the chain is not easy to make friends too, small and medium corporate website, maintained at 30 or less is more appropriate, and Friends of the chain, though not the scope of garbage outside the chain, but it will be implicated in down the right, Friends of the chain, the more the greater the risk. 2, the promotion of connection: First, Baidu drop-down box, Related searches, word and other tools to identify sectors chase long tail keywords, and then analyze them for these long tail keywords explicit and implicit requirements demand: such as: (1) "2013 Hunan Self Zhenti" implicit demand of the word must be "2013 Hunan Self Zhenti answer"; (2) "Pork practice" is the word dominant demand and production of raw materials production steps, purchase of raw materials where it is implicit needs. (3) summer go to the supermarket to buy a bottle of water, latent demand is of course ice water. The release of the page outside the chain plus the implicit demand that keyword link, the user will not hesitate to click on, and is continuous clicks, will not only increase the steady stream of website weight, but also increase the site's audience, in fact, a good way for the best of both worlds, Chongming course you know the various relationships, well, today's lesson is temporarily high a paragraph on the chain there are a lot of things, of course, the above is purely personal point of view, if insufficient, please understand, and I are constantly seeking to do outside the chain of promotion of some inspiration, I do not know how Tell me what advice, but as a good push hands, this can indeed help novices joined the line quickly find inspiration, so you become a stand long on the road fast driving. Come on! My colleagues, so that network optimization into the era of rapid development. And the king of mutual encouragement.
