This is a rather crude metric because it presumes one can monetize all the traffic they receive AND one can generate as much profit per visitor as Google does. Anyone who could do both of those would likely displace Google as the first consumer destination in their market (like how many people in the United States start ecommerce searches on Amazon.com rather than Google.com).
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.
I learned a lot from you and now make a couple hundreds per month in extra cash thanks to your advice. You provided us with great content and a great tool. I’m very happy for you. I have to say though that I’m sad you sold… customer service is so so so far and I know it’s cool for owners to sell subscriptions instead of selling it for a one time fee and I know it’s a new trend online but it’s really a trend I don’t like as a customer… Anyways. I’m very happy for you. Many thanks and congrats !!!
I want to share how and why I sold the company in order to both educate and inspire potential software entrepreneurs. I certainly don't know everything and obviously companies sell for much more than I sold Long Tail Pro for (I won't be featured in Tech Crunch anytime soon); however, I'm willing to share what I have learned and hopefully that can be beneficial to a few of you.
