Trust crisis approaching search engine

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Search engine (engine) means to collect information on the Internet according to certain strategies, to use specific computer programs, and to provide users with retrieval service after organizing and processing the information.

From the user's point of view, the search engine provides a page containing the search box, input words in the search box, through the browser submitted to the search engine, the search engine will return to the user input information related to the list.

In the Search engine classification section We mentioned the full text search engine from the site to extract information to build a Web database concept. The search engine's automatic information collection function is divided into two kinds. One is a regular search, that is, every once in a while (such as Google is usually 28 days), search engine actively sent "spider" Program, a certain IP address range of Internet stations to retrieve, once found a new site, it will automatically extract the site's information and Web site to join their own database.

The other is to submit web search, that is, the site owner actively to the search engine to submit the Web site, it in a certain period of time (2 days to several months) directed to your site sent "spider" Program, scan your site and the relevant information into the database, in case the user inquiries. As a result of the search engine indexing rules have changed a lot in recent years, unsolicited Web site does not guarantee your website access to the search engine database, so the best way is to get some external links, so that search engines have more opportunities to find you and automatically your site included.

When a user searches for information with a keyword, search engine will be in the database search, if found with the user requirements of the content of the site, then use a special algorithm-usually according to the page of the keyword matching degree, the position/frequency, link quality, etc.-to calculate the relevance of each page and ranking level, The links are then returned to the user in order, depending on the degree of relevance.

Data show that at present, our country at least nearly 200 million people use search engines, big to see a doctor to go to school, small to eat shopping, many netizens have formed in the decision when the first Internet search habits.

But today, a number of companies offering search services, driven by commercial interests, are either intervening in search rankings or doping ads in content rankings, leaving search content far from just, and companies themselves experiencing a crisis of confidence.

Most people who use search engines have had such an uncomfortable experience, clearly they have to search for a knowledge of something to introduce, the results of the search for the content are ads, have to wade through several pages before the relevant content.

For example, using different search engines to search for the word "diabetes", netizens may get different search results on the home page, some of the first dozens of are all kinds of links to treat diabetes hospitals, some of the first information provided is the recent focus on diabetes news, or the medical explanation of diabetes. In fact, even if the public is looking for a hospital to treat diabetes, it is disconcerting to find that the top few hospitals are obscure.

In the context of the search engine's impartiality, the Chinese Internet Association held a forum today, hoping that the industry could reach a consensus and provide impartial search results. Lulin, vice president of the association, even said that the search engine's objective and fair has become the key to the healthy development of China's internet industry, because search engines are 200 million or 300 million of Internet users query the main window of mass information, directly affect the way people perceive the world.

Search companies have been repeatedly questioned

As long as you pay, the company that provides the search service is likely to screen or delete negative information that customers dislike, as long as you pay, no matter who you are, no matter where your company is, and how big it is, you can be ranked top of the search rankings for relevant keywords.
