Presumably do optimization friends are very clear links in the whole site optimization process played a role, friendship link is to attract spiders and transfer weights of very effective skills, is a high-quality outside the chain. But do you know how to change links? Friend Chain Exchange seems simple, but in fact there is a lot of knowledge, there are many details need us to pay attention to, today summed up nine is not suitable for the exchange of friends chain:

No.1: Improper swap snapshots are not normal. Snapshots are one of the best data to check the overall performance of a site. Snapshots are preferably the next day, followed by snapshots within three days. If more than 7 days, or even a snapshot is a long time ago, then you'd better not exchange, of course, we do not do too stringent snapshot requirements, take 6.28 Baidu's K station events, a lot of normal high weight of the site may have a snapshot of abnormal situation.

No.2: It is not advisable to exchange cross links. Unless you have this demand, otherwise the author is insisting that we do not recommend this friendship link. If your site has a large number of cross links, it is easy to be detected by search engines, and think you are doing station group, or purchase links. The impact you know. For this point, the author's suggestion is to use the Excel document to make a link record, as shown in the following figure, we can clearly record the exchange of friends chain.

No.3: not suitable for exchanging inside page link. This is not absolute, if the other side of the site's internal page weight is very high, it can also be considered, if the other side of the site when the weight included in the page and so on, so even if the other party said much better, I do not recommend you to exchange.

No.4: It is not appropriate to exchange the link with JS code. This is a lot of friends to change the link when neglected. Check the side we can put the mouse to the other side of the site's friend chain, look at the status of the address is a jump address, and we can view the site's page code to see if there is a jump code, as shown in the following figure.

No.5: It is not appropriate to exchange export links too many links. According to the cake principle. The more people you divide, the less you get. Even if the other person's weight is 9. But he has a good hundreds of links. According to Google PR formula: PR (a) =d+ (d) * (Web a PR value/page a export link) + ... (d) * (Web page n PR value/page n export link). According to this formula, from this site you pass over the weight of less, on this we exchange friend chain, do not just focus on the other side weight is how high, export links often affect more.

No.6: It is not advisable to exchange links containing nofollow labels. Nofollow label to do optimization people should be aware of its usefulness. He would stop spiders from tracking and also prevent the transfer of weights. The Query method is also very simple, we simply open the other side of the site page of the source file, to see the nofollow things. Of course, is not necessarily not to change, if it is some large flow of the site can be changed, although the label, but this can also bring our site a certain amount of traffic. As we know Baidu experience of the chain has nofollow tag, but Baidu experience of the chain can be very good for us to bring traffic, we can also be appropriate construction.

No.7: It is not appropriate to exchange the link of the rules limit. The specific example of the following figure, we know that the robots file can be shielded search engine amount of spiders, if the whole Friendship link page will be blocked, then you change the link is to do a one-way link to him. Of course, if you are in order to obtain a certain amount of traffic, but also can be exchanged.

No.8: It is not appropriate to exchange frame frame structure links. Frame frames are now rarely used, but they are not absolutely useless, and this structure is very unfriendly to search engines. You should also pay attention to the exchange.

No.9: It is not appropriate to exchange unrelated industry links. Today's search engine algorithms have been very intelligent, and search engines are more concerned about the relevance of the link, if the other side of the site and your site is not relevant, then the quality of links will be greatly compromised. Don't repeat it.

The exchange of friends seems simple, but it contains a lot of knowledge, we need to pay attention to a lot of the details, otherwise, not only is wasted effort, but also may cause your site to be unnecessarily punished.
