Bruce Clay describes the importance of using advanced search operators for Search Engine Optimization (SEO) in order to find specific information:

"Search engines find what you tell them to search for. A typical search will often return too many results or even results that are not relevant to the subject at hand. Therefore, search engines such as Google, Yahoo! and MSN came up with tools to narrow the search to obtain the specific information being requested.

Operators modify the query when asking the search engines for specific type of information that a general search cannot provide. These operators have a particular meaning to each of the different search engines, but not all engines accept the same operators." [2]
