How Google works:
Basically, Google is a crawler-based engine, meaning that it has software programs designed to "crawl" the information on the Net and add it to its sizeable database. Google has a great reputation for relevant and thorough search results, and is a good first place to start when searching.
Google's home page is extremely clean and simple, loads quickly, and delivers arguably the best results of any search engine out there, mostly due to its PageRank technology and massive listings. Google also earns high marks for its maps and searches for images, videos and blog posts; you can even search inside books with Book Search. However, search experts say that no single search engine provides the most relevant results for all queries. Google is also ranked number one because more people use it than any other search engine.
Part of the reason google is so successful is, as with most successful technology companies, they first started specializing in one area and after mastering that they moved onto other things. Not dabbling in other areas such as email, maps, finance allowed them to concentrate all their time and resources on just searching the vast world wide web.
