I will use the tool to pull in a lot of keywords related to a theme and group them into relevant topics. These topics will either become their own content page or will be combined with other topics to create a page. KeywordTool.io is similar to other tools out there such as Uber Suggest, which I've used for a long time, but it tends to produce more keywords and it provides search volume for the keywords.
Long Tail Pro by Spencer Haws is the most useful keyword research tool that you can use for your internet marketing. Thousands of webmasters depend on the tool to generate thousands of keywords. It is such effective that it has dominated the keyword search market for the few years it has been into existence. It would cost you less than one hundred dollars to have access to this important life-changing 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.
