Google – search engine

Google was the largest and the most versatile search engine on the Internet. The search engine had a robust workload and query-processing abilities. Realizing the importance of a fast, scalable search engine, Google employed linked PCs to quickly find the results of a query. This resulted in faster response times, greater scalability and lower costs. Google used PageRank10 and Hypertext-Matching Analysis11 technologies to provide fast and accurate results. Besides, it employed special software robots called Spiders that built a list of important key words found in the millions of websites on the Internet. This process of automated listing was called web crawling.

About 95% of Google’s revenue came from advertisements, primarily through its two popular offerings, AdWord and AdSense.
