Baidu will manually tamper with these search results.

Recently, Baidu search engine is having problems again. Lulu, a well-known writer, denounced Baidu Search on Weibo, bluntly stating that Baidu Search has become a scam platform. The reason is that when Liuliu searched for "Shanghai American Consulate", there were many advertisements for visa agencies in front row of main page.

As a website building and promotion company, we are keeping a close eye on news and developments in Baidu search field. When I was informed of this information, I searched for "Shanghai American Consulate" and found that there were no ads on home page. Not only that, but search results for long tail keywords and consulate related words, all advertisements have been removed. . Obviously, Baidu artificially interfered with search results.

Using this as an "introduction", I want to systematically analyze what measures Baidu has taken regarding manual intervention in search results?

Brand Protection

Because of medical advertisements of private hospitals, Baidu was once brought to fore, especially so-called Putian Department, which caused many search users to suffer. After many vicious incidents, Baidu's search launched "brand protection." It is mainly intended for businesses and webmasters with registered trademarks. Such businesses can apply for brand protection in Baidu Search and Baidu will consider them. After passing review, on one hand, competitors cannot use "brand name" for bidding, on other hand, after passing review, official website of brand protection company is often first to appear.

The author entered "Putian University Affiliated Hospital", and hospital's official website ranked first, and there was no advertising. It is one of three hospitals in Putian. It can be seen that brand protection has a significant impact on search results.

Initial Protection

In 2017, Baidu launched original protection. As long as it is original content, Baidu will display it first. In addition, Baidu also launched original protection in Baidu Baijia.

By presenting original protection, you can improve your website's ranking in keyword searches. Obviously, this is also a way of artificially interfering with search results.

Delicate interference

Compared to Google, Baidu clearly engages in manual interference with sensitive keywords. However, Google doesn't seem to want to do this. Trump recently accused Google of being politically oriented because a lot of negative news about Trump came up when searching for Trump. So Trump blamed Google.

As far as we know, back in 2013, Google launched an interference detection tool. With this tool, webmasters can check if Google has intervened and if web pages have been taken down. It's actuallyshowed Google's "neutral" stance and no human intervention.

Sending a broken link

What if I don't want any content on website to appear in Baidu's search results?

If it's Google, method is very simple. Just use webmaster tool and submit broken link to have it removed. Usually within a day or two. It can be seen that this is a processing algorithm.

But Baidu search is different: many broken links often still exist after a few months. The webmaster needs to fill out a "Dead Link Submission", once submitted, a valid market often takes up to three days. It can be seen that artificial sons will very likely intervene behind this.

The above four points represent Baidu's manual intervention measures and practices in search results that author has observed. Whether some of these are actually manual interventions requires further verification.
