As a webmaster, the exchange of friendship links became our compulsory homework, this is also as a very important site publicity, a lot of webmaster friends through the Friendship Link Group QQ, active application, advertising cooperation and other means of hard to exchange links to get a higher weight, higher PR, but there are always some people, Just want someone to link to them, do not want their own site links to appear other site links, so the brain, through a variety of means to try and others to exchange the friendship link, if the good webmaster do not check, it is easy to recruit and unaware, here all the way to read the work of several common link scam, Share, according to the common degree and the difficulty, listed in sequence so seven kinds of common link deception:

A, the site was blocked by Baidu, there are still PR

Many webmaster exchange links of friendship, only consider a Google PR factor, as long as the PR to meet the requirements on the exchange of links, but some sites, due to excessive SEO and other reasons, was Baidu blocked, in Baidu search not to this site, but in Google's index still exist, and has pr. Many such sites, are crazy to apply for links to the expectation of being indexed by Baidu, however, there is an article "uncover the problem of search engine" has mentioned, and such a site exchange links do more harm than good, it is easy to suffer associated punishment. At the same time, the need for the vast number of webmaster attention is that there are some sites, although not blocked, but has been blocked by Baidu dangerous, it is best not to exchange links with it, such as the page has obvious keyword piling up, and other servers and so on.

Second, do not use the form of direct URL link to use a jump link

A lot of online self-help friendship link system, his links are not directly to the cooperative site, but link to a page of their own, through the page to jump to other sites, so most of the practice is to monitor the number of links clicked, however, this approach to the cooperation of the site may pose a risk, First, the quality of the link is inferior to direct link, second, if not using 301 jump, but also may cause search engine rankings unnecessary trouble. Therefore, if you encounter such a site, the webmaster must strive to use direct links, rather than using jump links.

Third, use the JS statement output link Code or use I contain link page

Because the vast majority of search engines do not crawl, analysis of the ability of JS statements, so, through the output of JS link code, search engines can not crawl to, at the same time, search engine and can not be very good to crawl the content of I, so the use of I contains links to the link between the form of Both of these links are invalid links, a simple way to Judge view the source file of the other link page, if you can not find your page address, it should be the above 2 ways to output the link, there is an exception, the page directly using the JS statement output link, such as write ' [a href=http://www.yiludu.cn/ref= nofollow] "all the way to read [/A] ' such a form, is also a JS statement, but the page can be found, such links, in theory, search engines will crawl to, but will it be equated to the ordinary link, is still unknown.

Iv. Friendship Link Area use Nofollow property

Google launched the Nofollow label is intended to better control the page's external links to create the loss of the page's PR, but at present, this attribute is also an ulterior motive applied to the friendship connection, these people's friendship links at first glance no problem, but view the source of the page, You will find that the link code is such a form [a href= "http://www.yiludu.cn/" ref= nofollow] all the way read [/A], more this one nofollow attribute, the page's PR will not be passed, although Baidu currently does not support this attribute, But the value of this link has been greatly reduced. As in the third case, the way to prevent this kind of deception is to look at the source file and see if there is such a property in the linked statement

V. Link code outside of HTML

The normal Web page starts with the [HTML] tag, and the [HTML] tag ends, forming a complete Web page. But, at present, found there are some stationmaster, write the linked code outside the [HTML] end tag, because [HTML] represents the end of a page, if the link code written in [HTML], can not guarantee that the link will be the search engine normal crawl, this situation also requires us to do a number of links in the mind.

Six, page export too many links

Google's Guide to webmasters specifically advises webmasters to control the page's export links within 100 too many export links will dilute the weight of the page and PR, thereby reducing the meaning of the friendship link, to PR as an example, if a PR5 page only 1 outside the chain, So passing the past PR may be 5, and if a PR5 page, there are 100 outside the chain, then passing the PR may be only 0, 05 or even less, the PR calculation is not as simple as above, but a principle is known, the more outside the chain, the less the distribution of PR. This requires our webmaster in doing the link, do not simply look at the PR itself, but also should consider the number of pages outside the chain.

Seven, the PR deception

Here to tell you a case, one day, a domain name for peopledaily dot com point cn site, suddenly find the door to exchange links, PR is 6, but, as a site to do SEO, domain name to get so strange, it is inevitable that people suspect, at first I thought it was PR hijacking, Then in the WHOIS query registration time, found that the registration time is still very long, later, this site Baidu, found that the original site is to do photography, and in the domestic small famous, PR is so high, just do not know what the reason, this domain name was bought away, made a new station, and PR did not update in time. Because the site theme changes, such a site, his PR will not hold

Long, it is likely that the next update cycle will be zeroed out. So, encounter PR too high website, suggest you two times check, first check registration time, too short le PR too high may be the PR hijacking, second check the site outside the chain source, whether with the current site with a theme to prevent deceived.
