On the 10 principles of the Construction of outer chain

I believe that the friends who have contacted SEO have heard the "content for the king, outside the chain for the emperor," said that the most important SEO two factors, then, what kind of chain is good outside the chain, in the choice of what principles?

1, outside the chain source page itself weight, a chain equivalent to other sites to their own site cast a vote, but the score is different from the high weight of the page from the chain of the score is relatively high, the ranking of the site more good. Specifically speaking, including the external chain of the source of the site's PR, included in the number, whether the directory is open, domain name age and the first time included in the site and the theme is often changed, and so on, the longer the history, the more stable site search more trust.

2, the external link source website update and snapshot situation. Site pages in the search for snapshots update faster, snapshot date is very new, indicating that this page of spiders often patronize, then means that you add to the link will soon be detected, and produce results. If the snapshot is a few months old, it may take several months before the link is detected.

3, the number of export links to the external link source page. The more links that are exported on the page, the less weight each link can be divided. Sometimes do friends when the chain will find that some sites, although the weight is very high, but export links as many as hundreds, from such a page and the effect of the chain will not be good where to go.

4, outside the chain source page and the relevance of the site content, outside the chain source page and the content of their own site more relevant, the ranking of the site more benefits.

5, the anchor text outside the chain, the choice of keywords related to the site as anchor text will be more favorable than the anchor text irrelevant to the ranking, in addition, the external chain anchor text adjacent to the text, but also affect the effect of a factor outside the chain.

6. Generally speaking, the larger the number of the chain, the more votes, the ranking of the site more helpful, except for the junk link.

7, outside the chain appears position, generally speaking, the body appears in the outer chain is the most natural and best.

8, outside the chain source page also points to which sites, the content of these other sites with your site pepper, how quality is also an influential factor.

9, to avoid being considered a spam link, if the site's links are mostly from the forum signature, blog comments, etc., and the lack of text or posts in the more meaningful referral links, but also unfavorable, easy to be considered a spam link, serious words may be punished.

10, from the authority of the outside chain. Many of the friends who do optimization think that the Edu to gov suffix this kind of General people registered domain name outside the chain effect is relatively good. In fact, according to the official law of search leads, these domain names are not inherently higher than other domain names. Just because the use of these domain names are most of the government and educational institutions, the quality of the website content is generally relatively high and authoritative, from such a site link general effect is also relatively good.
