Keyword Researcher is an easy-to-use Google Autocomplete scraper. Once activated, it emulates a human user, and repeatedly types thousands of queries into Google.
Each time a partial phrase is entered, Google tries to predict what it thinks the whole phrase might be. We simply save this prediction.
And, as it turns out, when you do this for every letter of the alphabet (A-Z), then you’re left with hundreds of great Long Tail keyword phrases.
