Seed keywords presents a unique tool that users utilize in generating keyword ideas from other individuals. You need to begin by creating a scenario in a question form by asking people what they would search for in case they are looking for answers to their questions.

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.
