An equally profound as readable history of online search and its revenue models tells the search engine expert John Battelle. It is fascinating to lead once again in mind, * That of the Altavistas and Excites the early Internet days quasi only Yahoo has survived. * Google, founded in 1998, for just over 5 years, determined the Internet Search * That the Google Adwords exist as source of income on the Google page only since about 4 years * That the Google Adsense Concept (Google Ads on any websites) was introduced only two years ago. John Battelle anticipates that will do for the Internet search so much that he did not want to be limited to the Google story itself. So he makes a virtue of necessity and describes the waves of the Internet search. He makes it clear why certain concepts and ideas have prevailed, and always returns to the main idea: The perfect search recognizes the intent of the searcher. The relevance of the results is the nuts and bolts to increase, keep working all the known and unknown vendors. Conclusion: A book that is just as interesting for Google fans as for those who want to be clear about the importance and influence of search on our lives. Search algorithms are a highly technical field. Battelle, however, it is possible to describe the technical approaches generally understandable.
