With the rapid development of the Internet, more and more information on the Internet, the Web site is more and more, and we all know that search engines can not crawl all the site page information, Baidu official also made clear that spiders will only crawl to as many valuable resources and maintain the system and the actual environment of the page consistency, The goal of search engines is to find resource links as quickly and completely as possible, and to improve crawl efficiency, only so that spiders can satisfy most of the sites. Because of this so for different web search engine crawling collection situation is not the same, this will be the quality of the site rating.
A high quality site for crawling will certainly be able to obtain more quality resources, can save a lot of time. Baidu for Sina and the crawling of small sites is certainly not the same, so to the quality of the site rating, through the level to determine the extent of the site needs to crawl, thereby improving the efficiency of spiders. This is equivalent to a business to recruit talent, can not be a person to visit, in order to save time, many enterprises will attach importance to diploma, and this is a job-seekers of a rating, there are middle school, high school, university, graduate students and so on, high rating of nature will be more business interview opportunities, Even higher ratings do not have to interview directly. Search engines are also like this for the new station rating is certainly low, included also less, for the general station, the level will be high, crawl frequency and quantity will gradually become more, and for some large well-known stations, the basic is constantly in the crawl, and basically no audit, directly included, which not only improve the efficiency of search engines, but also meet the vast majority of user needs.
How do search engines rank?
Obviously this rating is not simple by artificial can be completed, some sites will be artificial judgments, and most of the need for more intelligent methods, through data calculation in the station automatically found the law to complete the quality rating.
First of all, search engine combined with artificial mining a batch of excellent quality site, as a basic set of database system, reduce the cost of anti-garbage cheating, improve the stability and authority of the system search results, reduce the adverse reactions of users, select a set of user experience to extract the characteristics of these pages. Like what:
1, Baidu Weight
Baidu weight for the site quality rating is a very important factor, is a site important degree and the degree of user demand a direct experience, but also the overall situation of the site is a condensed, so the general weight of the high value of the site represents high credibility and authority, which is critical to the site rating.
2, included speed
Some of the information is very rich Web sites, especially some of the integrated category of news sites and even such web sites such as blogs, forums and other products. Once the new information is rich, in a few seconds will be Baidu crawl, and released through the keyword can be retrieved. An occasional second is not a statement, but if a Web site published content, has been accustomed to a second, that means that the search engine has been trusted to this site, the rate of habitual high performance not only in the search engine value, but also to explain the quality of the site's article, the frequency of the update for a long time good, Description The website is a qualified news source.
3, relative included quantity
Relative to the number is the actual content of the site and the search engine to retrieve the content of the ratio. The total number of a Web site, indicating that the content of the site is rich, but the relative amount of more direct response to the quality of the site is good or bad. Only the quality of the site is relatively high, the search engine on the site more attention, the relative amount will be relatively high. For a website, the ideal state is the relative amount and absolute collection is very high.
4, outside the chain quantity
After the continuous filtration of Baidu, the remaining site outside the chain of quality more and more high, at present, the site has a relatively large number of outside the chain directly indicates that the third party site for your site recommendation, although the role of the chain in the decline, but you can go to see those large sites outside the chain is certainly not less, the site is the need for effective outside the chain recommended.
5. User Participation Amount
User participation, and the interaction between the site more and more by the search engine attention, including user Content participation, user clicks, user sharing, comments, collection and so on, including 360 "My Search", Baidu is now in the search results page to increase the user behavior is the search engine for the user vote attention, And a good user vote will be more and more involved in Baidu's quality rating of the site.
Of course, there are many features of this quality site, wood seo here is not one by one examples, according to these characteristics, the search engine will give different sites for intelligent rating, distinguish between quality sites and inferior sites, which and search engines to the site to sort the process of scoring is very similar, through the comparison can distinguish between the level of different sites , of course, the middle of the process will certainly not be so simple, need very complex data calculation, which does not have the same industry different characteristics of the site rating standards will not be the same.
Secondly, in the distinction between the quality station and inferior station, is not finished, good or bad, there is a need to continue to hierarchy quality sites and inferior sites continue to subdivide, that is, continue to the first step of the process extraction features, continue to be based on the standard quality score, and then constantly repeat the rating. Or for example, middle school, High school, university degree that also has the difference, the university degree has the inferior student, similarly the junior high school degree has the top students. So the search engine for high-quality stations and inferior stations need continuous subdivision, this is a very complex process, the process is ongoing, the most inferior resources are excluded, just as a search engine crawl imperfect when necessary supplement, belong to the back-up.
Search engine will be quality site and inferior site subdivided into a number of grades, these levels to distinguish between the quality of the site, so as to affect the spider for different levels of the site's collection control, but also affect the selection of low quality web pages. And this rating is ongoing, so in the optimization process needs to continuously improve the quality of the site features, and to learn from the advantages of other sites, to complement each other. Once the characteristics of the site gradually become high-quality, the search engine will give the site a good quality rating, so that the search engine will pay more attention to your site, so no matter the inclusion and ranking are beneficial.
