Google is probably one of the undisputed best search engines. One of the reasons for the quality of search engine results on Google is sure of is that the algorithm as well. This algorithm was always kept strictly secret in order to avoid abuse by manipulation and also to give the competition no information about their own work.
Udi Manber, the vice head of department of “Quality Search” at Google, now has nevertheless been at least a small part of the search algorithm known.
The best known part of the algorithm is probably the PageRank, which Page and Sergey Brin, the founders of Google, was developed by Larry. But there are still many other variables, which refer to the ranking influence. For example, language models are also, therefore, dealt with how the language and synonyms used in creating the rankings. The timeliness of a search also plays a crucial role. Thus, almost certainly to be listed in a search that relates to a current event (such as news), on the top ranking new pages and recently updated pages. In addition, personal preferences of the user flow, even with the algorithm.
Furthermore Manber adds that there is a team with Google to improve quality. There are automated quality controls, which are made every minute and regular checks of the overall quality, which are mainly controlled the modifications to the algorithm necessary, whether they are an improvement or not. In 2007 Google released an average of nine improvement of the algorithm, corresponding to 450 a year.
Another team deals with new user interfaces. Here attention is paid to particular simplicity and usability.
Finally, he mentioned that there is also a large team within Google is that to get engaged in spamming and the related illegal practices a good ranking in Google (keyword: keyword stuffing, hidden text, etc.). It is used a lot of energy trying to ban such sites from the index.
The whole thing is ultimately necessary to meet the growing demands of the users. Finally, Udi Manber mentioned that it is planned to give the banks more often a small update as to what criteria were composed from the search engine results.
The search engine optimization, this information is not too much to bring, however, as these are kept very general and not allow any concrete conclusions. However, they can help some of the theories that are circulating in the professional sector to be verified or where appropriate, to expose as a myth.
