Fuqing SEO Blog Exchange friend chain principle has three. One is a peer or industry-related; the other is to talk very Huan, meet the bosom friend, three is the weight is quite, taller than me of course good, low that is not good to say.

Fuqing SEO Blog Online Two months time, every day adhere to the original, pen. Now love station query to reach the weight of 2, webmaster tool query Weights 1, according to the background monitoring flow, the author thinks webmaster tools data. Now Fuqing SEO blog Each regional keyword ranking is the first, the article released almost seconds, the snapshot is normal the next day, of course, also see two times 1 minutes of snapshots, just met Baidu update.

Yesterday afternoon when the time to work Yantai SEO sent me QQ message, said that I put his friendship links to Nofollow, but also sent a screenshot. A question is through webmaster tool inquiries, I ADO immediately own hands-on query, the results show the other side of the link in the author's SEO blog inside was nofollow, but also picture links. The other tool query, the result is the same.

Yantai SEO is the author for the first friendship link, then I wonder, how is this? Open your own SEO blog to see the source file, locate the links, found no exception. As soon as the work was not carefully checked, a home immediately turned on the computer to make two inquiries.

Query each other's friends chain, does show my SEO blog to his links to Nofollow, but also strange picture links. The author's friend chain currently has 5.

Query the author blog friend chain, in the filter nofollow link situation only shows 4 links, and Yantai SEO links are indeed not in the list. Choose not to filter nofollow links, there are 8 links. In addition to Sina Weibo and Tencent Weibo, found that the link to Yantai seo is a picture link in the form of the query results show, but also an additional picture link.

So I carefully again the first page of the source looked, found in the link source of the above is the latest comment source, which has yantai seo comments. This source is an img alt= ' yantai seo ' src=gravatar avatar form appears, and did not appear in his link, but go to the corresponding comments page, Yantai SEO did leave a description of the link, but the link to the message I all in the form of nofollow filter.

So I suddenly realized that Yantai SEO message deleted, everything is normal. Through this accident, I still have some sentiment.

1, webmaster tools are analog search engine for the source code from the top to the analysis;

2, the Friendship link display result is the first link appears the situation to be whichever;

In addition fuqing SEO remind, we exchange links when we should pay attention to a few points:

1, to see whether the source Link has nofollow properties, 2, to see if the link is included in JS, 3, the form of links into a jump, 4, whether the link within the IFRAME frame.

Of course, there are some advanced techniques, such as through the Code to guide spiders, so that spiders do not crawl friends chain, using the relevant technology to judge visitors and spiders to give different pages.

Actually friend chain cheat a lot of tricks, Fuqing seo just enumerate common, under general circumstances I suggest through source file, webmaster Tools, Baidu snapshot to see whether the normal show friends chain to decide whether to be deceived.
