Long Tail Pro Looks Like Google Adwords

I have recently start using Long Tail Pro its a paid software for keyword research.
But requires a Google Account to use and give Keyword ideas from Google Adwords.
So, why we are getting paid for this Software as Google Adwords allows us to fine the best keywords for FREE.
If you know any method to use Long Tail Pro premium Features please Share.
Thanks

The premium version lets you see the KC or Keyword Competition for each keyword. This number is supposed to let you know the competition of that keyword, something that Google doesn't do. The KC factors in a lot of things like Domain Authority, Page Authority and Moz Rank, among other things that Moz uses to evaluate websites.

I suggest you learning how to do KW research with the help of LTP. First, you should upgrade to Platinum version, which costs you $17/month (subscribe for 1 month only, I think 1 month is enough to learn KW research). The Platinum version allows you to calculate the KC of KWs, it is accurate 80% of the time. The next job you need to do is to find out the correlation between the KC and other metrics like DA, PA, Page Link, Juice Page Link, PR....After a while you will have a "sense" and can "gauge" the difficulty of KW by looking to the DA, PA, PR....without upgrading to Platinum, which will save you $17/month. After all, KW research is not something that can calculate by the number.

You could honestly do all of this in an Excel spreadsheet just as easily, with the SEOTools plugin, for free. Just download the keyword data and drop it into a spreadsheet, then use the custom functions from the SEOTools plugin to pull in data such as domain age and other metrics, then come up with whatever calculations that mimic programs like Long Tail Pro or Market Samurai. I've actually got one I am working on right now, and may share it once I work out the kinks. The only thing that is throwing me off are the blended search results in Google, which mess up my formulas to scrape the SERPs.
