Advantages and disadvantages of friendship links and avoidance of deception measures

Links are also outside the chain of the form, but is to both sides of the link, but this form of the chain is long-term effective, the general webmaster approved the number of links is about 30. Some friends say more than 30 will cause unnecessary trouble. Now do most of the links webmaster are still reference to the PR to measure, the general PR high site to find friends chain are relatively easy, this should be said to be a traditional web site culture, because of PR and change. Links also have advantages and disadvantages.

　　One, friendship links have what benefits:

Links can quickly enhance the weight of the site, if it is a high weight of the site to give you a one-way link, so the effect is more obvious, take the new station to say, the new station on the line that day, there are a few sites to you a one-way link, then you can also achieve the online collection of the situation, of course, the premise is the other side of the station weight is very good, There is no suspicion of cheating or anything. Links have other benefits, that is, when a site snapshot update speed is too slow, to find a few snapshots of new links to make a friend, so you can also take advantage of the flow of the snapshot of their own site, to achieve with other sites snapshot synchronization. Links can also help to improve the rankings Oh, how to say? If your site does a friendship link is a snapshot every day or the next new, then when the spider climbed to their site, can be the homeopathic climb to the friendship link this piece, found your site, it will climb down, found that most sites have your links, You will feel that your site is very friendly, will naturally give a better ranking.

　　Second, the lack of links:

1, easy to get into trouble, just like in ancient times to sit phenomenon. Because if you're down with a reason for being too optimized or otherwise, even be k off, you can not find the first time, then your site may also be compromised, friendship link equivalent to the campaign, you and each other to do a friend chain, the equivalent of your endorsement of each other's site, voted him a vote, then when his site appeared down right , you vote for him is considered the accomplice, and your website is also being compromised.

2, easy to make both sides of the link into one-way import. Friendship Link is one of the easiest places to cheat, if the other party in the link there set the nofollow, then the meaning of the word everyone knows, so that it will become their own site to each other a one-way import, while the other party hangs their own links, but he has been screen, The weight that leads to your site becomes zero.

3, the use of robots screen, a lot of webmaster are trying to make bidirectional into one-way, then remove the link is too obvious, the use of screen to do, through the screen of the relevant documents to link links to prohibit the index of spiders, this will also lead to a one-way link to each other, their own site does not have the weight generated.

4, the use of JS code, jump, picture function. I don't know if we've met, I have encountered, with others to change the time, change, I used to his station to see, many like to play the exciting webmaster friends like to use the form of JS code to do friendship, because the current search is not very good index JS code, It is also possible that he through the screen JS file to achieve one-way import.

5, easy to be removed, become a one-way link. I met a lot of reasons to remove the link friend, ask the reason, the answer is not, some say is mistakenly deleted, some say wrong, some say code problems, and some directly do not reply. Frustrating.

　　Thirdly, how do we avoid:

1. Check the links frequently. This really takes a kung fu, but in order to post friendly development of the website really want to do, every day to spend a few minutes to check their website Friendship link is safe, there is no change one-way, have not been to the chain and so on.

2. Look at each other's website source code, to see if the other source code has a nofollow attribute tag, that label is not a friendship link this piece.

3. The other side of the template, the interface is popular, because the general do garbage station are too lazy to change these, are directly with the original, the program with the template interface, so you can more clearly know whether the other side is doing garbage station.

4. See the other side of the site's friendship link block is not the use of JS code to write, JS code cheating cases A lot, directly lead to one-way link of the situation is very large.

Friendship links do well, can bring weight. Did not do well, can make the website to be compromised. Clearly understand the advantages and disadvantages of friendship links, so that we exchange friends in the chain when more handy. This article is exclusively provided by http://www.7254.com.
