The best way to get the most insightful data out of AnswerThePublic is to run a few reports with related keywords. Try to stick to one or two words at a time and then try the variations around it. You'll find you get very little back if you type in a full sentence.
Have a think about how the public could be referring to your business and all the different variations they may use. For example if you are a car brand, you may consider searching everything from your brand name and competitors but also car, my car, new car, used cars, car reviews as well as driving, motors and so on.
