Classification of patterns into groups in unsupervised way represents clustering. Clustering can be done in many ways and by researchers in many disciplines, like clustering can be done on the basis of queries submitted to search engine. This paper provides an overview of algorithms which are helpful in search engine optimization. The algorithms discuss are BB's Graph Based Clustering Algorithm, Concept Based Clustering Algorithm and Personalized Concept based clustering algorithm. All the algorithm works on the basis of precision and recall values, which are helpful in determine the efficiency of search engine queries.
