"Outside the chain", this is often referred to the majority of webmaster words, I believe that we listen to the ear on the cocoon, but it is undeniable that outside the chain of the site in all aspects of the role that is beyond doubt. Snapshot update frequency by the chain, the site keyword rankings outside the chain, the site included in the number of pages or to rely on the chain, but I want to say is not what the chain on the site are good, on the contrary, do a low quality of the chain is better not to do. So how to judge the quality of the site outside the chain?

Method One

We all know that a lot of sites, just opened the site once the search engine is included will have a considerable weight. This is mainly in the education industry, the medical industry, the industrial sector and government industry sites. Webmaster in these industries on the site to do outside the chain, although the relevant degree does not necessarily conform to the content of the site, but once included, it is also definitely a high-quality outside the chain. The reason why this kind of web site weight is relatively high, the reason is very simple, because the content of these sites are original, the main reason is because this kind of site is related to the country, of course, it is not our personal webmaster or other webmaster can match. Web engine to meet the country's policy will even artificially increase the weight. For example, such as gov.cn such a government domain name only government agencies can register, personal webmaster is in any case can not register, this from another aspect of the government's Web site weight affirmation is relatively high.

Method Two

From the point of view of time, the longer the chain of time to retain the quality of the chain is higher. Search engine every day to review the content of each site update frequency, the site's construction of the chain, the time is long, those low quality external links will certainly be slowly removed. Those who keep six months, a year or even two years of the chain is undoubtedly the search engine recognized the outside chain, which is undoubtedly high-quality outside the chain. But this kind of judgment method is not very easy, this need stationmaster long-term observation, accumulate. Through the daily observation of their site's external chain snapshots, the number of chain, to determine what is high-quality outside the chain, which is low quality chain.

Method Three

Method two mainly from the site itself as the starting point, through the observation of their own site snapshots and quantity to judge the quality of the site outside the chain, and method Three is the extension of two, which is through the study of similar competitive web site chain. For example, we do "mobile phone purchase" This keyword, we can look at similar sites, especially those with weights more weight than their own site, through webmaster tools to analyze their site outside the chain, to see where they put the chain building, through the comparison of snapshots, we are very easy to determine what is high quality outside the chain.
