We all know that the effect of friendship links has been weakened by Baidu, but the friend chain still has a certain role. In the current Web site optimization process, the exchange of links is the indispensable task. Although a lot of people already know the meaning of friendship links, but for the novice here I still have to long-winded, friendship links is the site and site cooperation between the way, can generate resources in the peer advantage. Practice is a friend of the chain in their own site in a specific location on each other's website logo, name, and so on, plus the link to the other site. The role is to allow users to enter a Web site through the link into the friend chain site, so as a friend chain site to bring a certain amount of traffic, but also from the friends of the chain site to obtain a lot of traffic, friend chain can also play the role of weight transfer.

Gayou chain must be in the Web page source code can find the URL and the name of the site, some outlaws in the exchange of friends chain through some cheating cheat friends chain, such as the friend chain site just write into the JS code, this approach can not bring friends chain effect. Friends of the chain is two sites to do each other's site links, can be text links, picture links, mainly to allow users to click on this link to enter the friendship site.

What are the benefits of that friend chain?

The most direct advantage is to get the flow from the friend chain, another, can make spiders easier to crawl your site so as to improve the site included. Web site traffic is the largest access to search engines, only by friendship links is not to bring much traffic. To obtain traffic from the search engine, we must let the site include more, friendship links is to improve the best method included. Here has to introduce a word: 17891.html "> Popularity." That is, the number of sites in the link to do, your site backlinks, the popularity of high, Baidu ranked relatively high, but the junk friends chain will affect the ranking, which is considered a factor.

The choice of friend chain also consider the following aspects:

1, PR value, this is a Google algorithm, the equivalent of Baidu's weight, a lot of webmaster in the choice of friendship will refer to this value, PR value to the higher the better.

2, link relevance, do link two site content must be relevant, can not be a station to sell fruit, a station to shoot the bar.

3, Friends of the chain of quality, the other side of the site can not be too many of the chain, because that site has been for so many site transfer weight, give you less, even if the other side of the weight is very high.

4, cheating on the site, in the exchange of the chain, found that the friend chain site is through cheating to get the weight, decisively deleted, otherwise it will affect your site.

The friend chain has the weight to be certain than does not have the weight the good?

Now many webmaster have a misunderstanding: is the right weight must be better than no weight? In fact, here I suggest that you do not have the view of the recognition, the right to the weight if the snapshot is not new, personally feel that there is never a snapshot of frequent updates to the good. For example a website weight 1, snapshot is September 2, 2013, a website weight 0, the snapshot is updated the next day. If I had chosen, I would have chosen the site for the next snapshot.
