First, to determine whether the chain is a problem outside the chain of principles-Real recommendation

Baidu to determine whether the chain is a problem outside the chain of the only principle: whether the user or other sites of the genuine recommendation, whether the specific quality of the recommendation significance.

Here is a key point: "Really recommended" what is the true recommendation? Similar to the convenience of the pages linked to some of the weather forecast train timetable such a page, but this is not very good to judge, the only criterion is to carry out the characteristics of key words, to determine whether there is an active exchange of links in the page trend. For example, to judge some commonly used link exchange words and so on. Here do not elaborate, the specific characters should be a lot.

2, cheating outside the chain

In order to deceive search engines, deliberately interfere with search engine sorting for the purpose, by the beneficiary website led, man-made intentional or machine-made outside the chain. including but not limited to: Anchor text cheating, buy high weight outside the chain, black chain, bulk mass increase of low quality chain, sprocket and so on. For this kind of outside chain, we carry on the Recognition filtering Foundation, simultaneously will link to the website to carry on certain processing, has the direct negative influence.

Here are a few key points is the "Purchase link" "Black Chain" "mass large-scale low quality chain" "Sprocket." How do I identify the purchase link? 1. Capture feature style, or feature HTML tags, specific tags can go to a large number of Taobao to sell links to find features, while in the keyword coexistence matching, such as gold chain, such as Golden chain, caught these links directly to 0 recommended degree.

"Black chain" recognition has always been a problem, as long as the 80% black chain characteristics of the basic even if successful, then how to do it, the first link in the following does not make weight calculation, as a cheat link, the style of the existence of CSS hidden in the calculation. Hidden and background colors are not calculated.

"Mass low quality outside the chain" to deal with large-scale first link relationship processing, let a single site multiple pages of the link to merge or only calculate 1 or 2 or a little more. Then you can calculate the link under the main domain, such as www.sina.com.cn only calculate slin.com.cn link then can eliminate the blog mass or a large number of two-level domain name accumulation of garbage links brought by unfair vote. Even if you send 10,000 Sina blog then calculate slin.com.cn the main domain name under the 1 links, this can let the blog mass failure, of course, is now so.

3, the garbage super chain example detailed

(1) The link from the search results page. Without an example, there are a number of links generated on the Web page of search results. This kind of outside chain will be filtered by Baidu, do not calculate link weight;

Search results page issued by the link, from the development point of view, these pages basically contain parameters, such as the equal sign "=" question mark "?" Parameter Pass "&" and so on, by filtering out these links can filter out 90% of the search results page issued by the link, then if your station is a dynamic page, then your inner chain in addition to the discovery of links should have no other use.

In addition, the article also talked about the forum signature cheat, this already is old cannot again old algorithm the search engine through the analysis style to get the link style, for example some user name adds the link behavior all is does not have the weight transmission. Search engines can distinguish between link attributes such as invisible links, hidden link border links, and so on, and nofollow and more cheating links. From a development perspective these things are strong, for the search of justice and customer experience has brought a rare benefit.

Of course, the current better algorithm or from the user's recommendation, is in the search results page of the page to click, of course, some black hat webmaster also use this for cheating. The first 24-hour ranking, Baidu Click on what is the use of this algorithm to the search results dare to intervene to simulate user behavior to improve the credibility of the page.

The high weight of the site normal links why than the weight of the normal link to improve the ranking effect is better, because in the Search engine internal link table has a page weight.

So the analytic algorithm model is like this:

Page weight x page recommendation x Link Nature = Final recommendation. The final recommendation + the weight of the page itself, that is, in the search engine inverted index through the calculation of the word stop words, TFD fid and so on these things obtained score. Then the weight of the user's behavior is ultimately equal to the ranking of the page.

Page Construction + External recommendation + User Behavior Recommendation = Final ranking.

Yes, forget an important thing is the time stamp of the page, the more time the new ranking the better.

Page Construction + External recommendation + Snapshot time Recommendation + user Behavior Recommendation = Final ranking.

This is the article. Of course, the more perfect search engine algorithm to bring people's welfare more, but also hope to improve as soon as possible.
