It is important to know what kind of outside chain is valuable in search engines. For example, you write an article, add a good link, flat and in high weight forum release, after the article integration, hyperlinks can be directly linked to a related article or website. This increases the user's experience, and can also increase the user's reading value, this link is necessarily very good. But if you post an article about a mechanical station in some forums, finally, add a link or anchor text on it. This is relative to the search engine, very simple to be seen. Such benefits are obvious, so they are not of high value.
2. The role of link transfer:
Links that exist in the Web site or in the article as the network changes, or add or subtract, this is affirmative; the site or the address of the article, in the Internet, like water ups and downs of the fluctuation of transmission. This is the law of the Web site, which can be recorded by statistical tools to the database. We can look at it from another way: the spread of the Internet, the URL appears against the law, even if the day before yesterday there are 35 single chain, may be lowered to 25 today, tomorrow will suddenly become 0, maybe today is 15, the day after tomorrow is 0; there may be a concentration of address links for these sites, Especially like blogs and forums. This is a very obvious interest event. Such events occur in less cases, for the search engine may not be punished for the time being, if there are too many abnormal events will be triggered, the site will be the search engine down the right, serious will be K.

From the point of view of the search engine will know that the network to promote the optimization of the forum, if there are several links to tourism articles, such as the case, what can be explained? In Search engine view, the construction of the site some problems, in the SEO forum to see, Just find a way to optimize or solve some of the problems in the website. This can be explained that if there is a link near the word about tourism, there are some reasons. In fact, we appear in the vicinity of the relevant word is this principle, this can not explain what, do not think I was deliberately doing outside the chain. If the site left a large number of URLs, are not related to the site, but did not leave a link in the travel site, it can only explain one thing-the benefits.
