1. A software program on a computer usable storage medium for performing a computer controlled method of determining the effectiveness of a search engine in performing searches in a search area comprising: computer code generating controlled relevant documents by manipulation of relevant search terms of documents in the search area based on a relevancy algorithm; wherein the relevancy algorithm relates to positions of relevant search terms in documents and the generation of the controlled relevant documents is done by placing search terms into various positions in the document in accordance with the relevancy algorithm and wherein at least 3 different controlled relevant documents are produced for a given relevancy algorithm with search terms placed in different positions in different documents with each document compared with the document relevant to the search area with absence of search terms in that document to generate the relevancy vector chart; using the controlled relevant documents to create a relevancy vector chart; and comparing results obtained from the search engine to the relevancy vector chart to provide a relevancy rating for the search engine with computer code using the relevancy vector chart to obtain a relative ranking of a plurality of search engines.
