Results are determined by Crawling. We sort the pages by their content and other factors and created an index that is over 100 million GBs, combined with algorithims (programs and formulas) to search thru the index for the correct result. 200 factors are part of the algorithim including site quality, synonyms, user content, safesearch. The results are produced in an .8 second are then ranked. Process is tweaked and constantly updated. Google monitors bad links and spam for websites. All this manages over one hundred billion searches a month!
Overall, nearly 17 billion explicit core searches were conducted over the month of February, with Google Sites again ranking first at 10.8 billion. Over that same time, Microsoft registered 3.6 billion searches, followed by Yahoo at 2 billion, Ask Network at 273 million and AOL at 145 million.
Every time you use a regular search engine, your search data is recorded. Major search engines capture your IP address and use tracking cookies (small files that replicate/taylor your interests from a website) to make a record of your search terms, the time of your visit, and the links you choose - then they store that information in a giant database. Private browsing/Incognito: masks your browsing history but does not hide it from websites-sites can still see where you clicked, information you may have entered and your IP address. The info is still linked to you , even when it is not in your history. Safari , Google Chrome, Firefox,Opera and Internet Explorer all have private browsing. Private browsing will not stop any records associated with your IP address from a browser; only history.
Tracking your searches can erode your privacy and lead to censorship.
In addition, those searches reveal a shocking amount of personal information about you, such as your interests, family circumstances, political leanings, medical conditions, and more. This information is modern-day gold for marketers, government officials, black-hat hackers and criminals - all of whom would love to get their hands on your private search data. In August 2006, the online world was jarred when AOL accidentally released three months' worth of aggregated search data from 650,000 of its users, publishing all the details in an online database.
