I'm trying to do some local SEO for a plumber for free. I live in Brooklyn which has a population of 2.5 million people. I'm typing in individual neighborhoods in Brooklyn followed by "Plumber" and it's saying there's no searches. For example, Bensonhurst is a neighborhood in Brooklyn with 150,000 population. Can it really be that not one person is typing in "Bensonhurst plumber" or "Bensonhurst plumbers" or "Bensonhurst plumbing"? Is this the case or is this tool just bullshit? Any other accurate tools I can use for keyword research?
