Answerthepublic.com

Answerthepublic is a service that allows you investigate the most common queries for any given words. With an input of one or two words in the search engine, the output it provides examines the most important entries and organizes them in semantic groups.

E.g., by inputting 'depression', the service will generate a diagram of the words that are most commonly looked up next to 'depression'. Depression: what, how, why, does, can, symptoms, etc.

For each of these clusters, there is a summary of the most frequently looked up queries: "how is derpession treated?", "why is depression..?", "does depression last forever?", "can depression be cured?", "what are the main symptoms of depression".

The search can be run for a specific country and a specific language. E.g. one could be looking for 'depression' in Germany, but focusing only on english string searches.
