I’ve got to say thanks for the introduction to Long Tail Pro, It’s because of this review that I even came across it in the first place, I’ve been testing it out for the past few days and it’s awesome. Already found some “low hanging fruit”, though I do still prefer Niche Genetics for the organic listings. This has easily replaced using Google’s keyword planner and a note pad. Thanks again 🙂
What I really like about them is extensive detail including the keyword difficulty. Ahrefs uses clickstream data to also show how many clicks you will get from the search engine. This is very useful after knowledge graph integration, as many keywords may have huge traffic but they hardly get any clicks from the search engine. Reason being, they get answers directly from the Google search result. Example of one such query is: “birthdate of any celebrity”
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.
