Friend chain traps are very many, because a lot of people in order to their own site rankings, in the exchange of friends when the chain is not so kind, but we are sometimes not see clearly, here let the website optimization company to take us out of this bureau, to see eight friends chain trap bar.

1> Generating static camouflage practices

Exchange links, you link to the other side of the index.asp, but this. asp file in the URL is not the first suffix, the real suffix is index.html then your link will become one-way. So the exchange of links to multiple check suffix.

2> advertised PR is hijacked

Although the role of PR in the end, we disagree, but high PR link no one refused. To be careful of some sites PR is hijacked through the PR, the site does not really have so high pr.

3> doesn't link you.

This is often used in the cross connection, because you made a cross connection, the other side seems to be done, but after a while you probably forget to cross the station, the other side will delete your link

4> secretly Delete links

In general, you do a good friendship link, the other side in a certain period of time secretly deleted, so you become a one-way link, so to regularly check links

5> reduce the weight of links

Links have a unique page, but this page only has a portal on the home page, other pages do not, so the permissions are very low. Normal website structure, generally each page has this link page entrance.

6> Use robots.txt file

Some of the links to the site seems very normal, but the use of robots.txt, so that search engines do not include links

7> does not pass weight

Links Use the nofollow attribute, or use the script to turn, such links are actually not a normal link, and can not pass any weight.

8>JS Script Steering

Some links are the use of JS script to turn, seemingly normal surface, in fact, if you do not check the page code, you can not find the script is actually JS

For the above eight-point trap, the site optimization company said that in addition to the day-to-day inspection, if found in the exchange of friends in the chain after a period of time rankings and other problems, it may be further examination, perhaps, we are in the Bureau can also be broken out of the bureau.
