This is a really straight-forward strategy. Contrary to popular opinion – small niche websites can actually still work. Basically, you create a small website that is hyper-focused on one long tail keyword. You create the very best resource on that specific topic and publish the very best content on the internet based around that long tail keyword. Monetize with something simple like Adsense, Amazon or another affiliate product – then just sit back and watch the money roll in every month!
Keyword Researcher is designed to search the Autocomplete databases of Google, YouTube, and even That's a lot of keyword sources! As you probably know, if you're building an authority site, or if you would like to become a dominant player in your niche, then starting with a large database of keywords (that your customers are actually typing in) is a powerful marketing tool.

As for the history of the company, as I explained, I created Long Tail Pro back in 2011.  At the time, I was creating tons of niche sites and was doing alot of keyword research and content creation.  I was trying to figure out what types of keywords would rank quickly in the search engines, specifically Google, and I was frustrated with the other keyword research tools (in particular Market Samurai) out there.
