With Google being by far the most visited website in the world, it is hard to imagine using the Internet without search engines to help you find the content or businesses that you are looking for.
Google, Bing, Yahoo and other search engines have two main roles. Firstly, they use robots to crawl the Web and build an index of websites and their individual pages.
Secondly, they provide answers when someone enters a query. Gaining a better understanding of how the search engines work is important for any online marketing campaign, since it is necessary to capitalize on the fact that most Web traffic is driven by the search engines.
