In the Webmaster group, these two dates what happened, undoubtedly became a hot discussion, I do this line of time is not long, this is what I saw Baidu the largest scale of a change, when their site suddenly K, I actively look for the reason, the different line of peers, careful analysis, careful observation, but also to the major forums to see everyone's feedback. Here are some of my own ideas:

1, Baidu Forum Bulletin

Believe that a lot of webmaster in the notice of Baidu Forum has read this text, the text of the braid time is 5.23

About the quality of the news station, the principle of the search engine on the low quality of the demarcation line, and will give the treatment, which is written very clearly, and even examples of what kind of low quality news content.

2, Google changed, Baidu changed

Google 2011 "Panda algorithm", an anti-spam search engine algorithm, designed to reduce the quality of the content of the site ranking algorithm. This March, Baidu Seo appeared Baidu remind you: SEO is a very important work, please refer to Baidu related SEO suggestions. In March, Baidu has been to some stations.

Following the "Panda algorithm", April 24 launched the first algorithm "Penguin algorithm", this algorithm is intended to reduce the power of those flooded with this ad site. At the beginning of May, Baidu in Baidu Webmaster platform released the "Web2.0 Garbage detailed strategy", and then is "Baidu will improve quality news station show, out of low quality news station."

Through the above two points, personally, this site is the biggest reason for the K, is the content of quality problems, webmaster will find that the site of K, the medical industry's site accounted for 80%, we know that the medical industry's website is the pursuit of quantity, Baidu included, the chain is full of tens of thousands of, hundreds of thousands of, But the real value of things are not much, the content of the site are you copy me, I copy you, Blind pursuit of quantity. I have met a network director, directly to me, you see the same industry site included, outside the chain, which is not tens of thousands of. Yesterday in the Webmaster station wandering, see someone launched the "6.28 Baidu K Station, the reason to decrypt" a vote.

Voting results, most sites by K webmaster, feel very innocent, feel that they did not use any cheating means, not collection, not false original. I do not know is K station Webmaster have no serious, careful analysis of your site is k reason, now do the site, especially the medical site, you say you are all original, no one letter. So wake up, those paralyzed classmates. Want to be reborn in this destruction, you must re-examine the quality of your site, no confusion is the content of the station or outside the link, now the quality is the only way to save the site.
