Web search query. Types[edit] There are four broad categories that cover most web search queries:[1] Informational queries – Queries that cover a broad topic (e.g., colorado or trucks) for which there may be thousands of relevant results.Navigational queries – Queries that seek a single website or web page of a single entity (e.g., youtube or delta air lines).Transactional queries – Queries that reflect the intent of the user to perform a particular action, like purchasing a car or downloading a screen saver.
Search engines often support a fourth type of query that is used far less frequently: Connectivity queries – Queries that report on the connectivity of the indexed web graph (e.g., Which links point to this URL? , and How many pages are indexed from this domain name?).
