Baidu algorithm upgrade Why the medical site frequently recruit

Recently found a problem, whenever a group of people complained that "my site has been K" "" site was down the right, there is always a first time to ask "Do you do medical?". It seems that the medical site has become the target of criticism, Baidu to the medical site as the focus of attention to the target. However, there is a reason for everything, why the medical site frequently recruit, each upgrade is a large area of injury, today I would like to analyze the specific reasons.

The image above is a right to drop the site, Baidu included 1304, the core keywords all in hundreds.

　1, the credibility of the site

The medical profession is most concerned about is the brand and the Prestige, after all, the hospital profit is very high, each patient medical treatment's reference basis mainly is according to the hospital prestige to choose. Now, the medical industry's network marketing is extremely confusing, as long as there are a few qualified hospitals in the network marketing in the integration of the two, there are many trickery, is clearly a small clinic, but the strength of their own blowing as God generally, leading to patients with medical treatment when deceived. Therefore, Baidu's natural search for the medical profession of manual audit more stringent, is the nature of the industry caused. However, Baidu bidding in dealing with this problem is also a mistake, just the site is down right, but in the auction still have rankings, which is completely contrary to the principle of natural search.

　2, the content of the site

The false original and plagiarism in the medical industry is the most serious, because the disease only those, a specialist hospital disease type is not much, so the article is nothing more than about symptoms, treatment methods, so plagiarism traces everywhere visible, such a site itself to the search engine on the list of junk sites.

In addition, the site contains a large number of floating window ads, banner ads, article content page inserted ads, seriously affecting the user reading experience. Too much advertising is an important factor affecting search engine judgment. We do not think that search engines can not be so intelligent, from your PV, from your browsing time, from your reading screen will be able to analyze.

　3, outside the chain problem

Medical web site generally has a professional SEO team operations, these commercial SEO, in order to quickly get rankings, the construction of the outside chain has its own set of "methods." Out of the chain list, dozens of out of every day out of the chain is not a problem. In order to be in the forum, the classified information website not to be deleted, but also can add a lot of keywords, the post content is often the title and the content does not match, copies some rubbish content. Raise a large number of blog accounts posted outside the chain. These outside the chain is very few soft outside the chain, high weight outside the chain, because time-consuming and laborious.

4. Medical Station Group

A hospital rarely has only one website, for example, the Tongji hospital in the picture above, Baidu searches out the website to have more than 10. Do station group, the same keyword, the same outside the chain method, the same friend chain method, SEO operations are the same. This approach, even if there is a ranking, but also let search engines difficult to judge, even more so that users can not determine which is the official website. The website that is unfavorable to the user, all is violate the search engine rule. Moreover, the station group SEO method is similar, cause a fall right, all sites are implicated.

Today's search engine industry has diversified, each search engine is trying to develop their own search experience, therefore, the site SEO needs to make a careful plan, do not do the user objectionable things, comply with the search engine rules to make the site for a long time.
