Links in the outside chain is a relatively high weight of the import link, very effective to provide promotion rankings, transfer the role of weight. In short, the link refers to you to my site with a link, I give you the site with a link. So very novice in the friendship link this piece is easy to ignore, very easy to be deceived, for example: Other people's website down right, all may implicate to own website or appears the keyword rank drop and so on question. A lot of veterans want to be in the friendship link this piece wants to take advantage of the novice, because the chain can bring a very high effect of the chain; then I will explain a few points for friendship links:

Clear Links Categories: Single link, mutual links, cross links

1. Down the right link: if someone else's site has down the right, then we have to consider whether to change with it; because someone else's website really has the right to drop, then we have to consider two: ① down the right will not implicate us, ② 11545.html "> we have any advantages;" First of all, we have to understand the Baidu algorithm said: If a site appears to drop the right is very large may be implicated in other sites above, resulting in a large area of the right to drop the problem but they can not find the right to reduce the problem; We know and reduce the right of the site to change friends chain is implicated in the role of the right, then we need to change it;

2. Garbage site: There are a lot of web sites need to change friend chain, novice are not paying attention to the situation and others have changed, then the garbage site will bring us what harm? Their website is to do black hat optimization, the occurrence of keyword accumulation, the page in a large number of irrelevant content, hidden links and so on. If we and he changed our site will appear down the right, keyword drop ranking, K station and so on some problems, we do not need and they exchange for friends chain.

3. Code Shield: Some very bad people use some code to block your links from losing weight, such as adding the nofollow attribute, or using some black hat technology to screen. This way they do not give your site a good transfer weight, simply you bring them a single link.

4. Withdrawal: General and others change friends when the chain will check each other to have their own links, then some people on the side with you in exchange for a few minutes immediately delete your link, let your site to bring him a one-way link. Suggest everybody drinks others to exchange the friend chain after one hours check the website has not been recalled the link.

5. Check: Someone to change the link with you then must look at the other party's information; for example: site: Home page does not, include the situation, the chain situation, PR value, weight, key words have wood rankings and so on information need our detailed observation. If each other is high weight, included very good, keyword rankings are good, and these to their own very helpful friends chain to change will certainly bring good results.

6. Insist: We all need to check the links every day, there is no one to withdraw, the other side has the right to drop and so on information; this is what SEO personnel must do.

Summary: The link is the highest quality of external voting links, can make the site to gain weight value to promote ranking role. Then we need to check the chain of friends to see if there is any problem to exchange with others. (To do the number of friendship links Wei Wei advice: We do the best friendship link 20 or less, is because the 20 are controlled within their own)
