The paper considers a classification of search queries: by geography: geo-dependent and geo-independent; frequency: high-frequency, medium-frequency, low-frequency; on competition: highly competitive, low-competitive; seasonal: seasonal and off-season. At the same time, vital, navigational, commercial, information and transaction inquiries are singled out. A single request can refer to one or more groups. Depending on the classification of requests, it is important to cluster requests to optimize the semantic kernel and increase the visibility of the site on search by query.
