You can use Keyword Researcher Pro with the best free keyword research tool out there, Google KW planner. Importing and exporting data is as easy as clicking a button. It’s all done at lightening speed too. There are tutorials of how to do this in video form on the sales page here and they show just how easy this tool is for finding those long tail keywords.
Mentioned in the above video is the Keyword Competitiveness (KC) feature within Long Tail Pro. With earlier versions of Long Tail Pro, you could only access this feature if you paid extra to upgrade to the Platinum version of Long Tail Pro. Pricing structures and the way the software is delivered has evolved over the years – and currently (as of the date I am writing this) all features of the software are included no matter which payment plan you choose. So right now – everybody who buys Long Tail Pro has access to this extremely powerful feature.
Keyword everywhere is another useful keyword tool. You can install it on either Firefox or Google Chrome. The tool will be able to show you competition data, cost per click, and Google Keyword search volume of multiple websites and keywords. This free extension can help you to save a lot of time. It can assist you to find long-tail phrases including their precise search volume, competition data, and CPC.

5. Use the Keyword Competitiveness “Fetch Now” feature. Now that your list is trimmed down after you applied all those filters in the previous step, you use the KC “Fetch Now” feature that saves you time in retrieving all that invaluable information. Again, depending on the number of keywords it has to check it make take a while (remember that LTP needs to retrieve information from several sources including Google and Moz). During this bulk check if LTP prompts with Google captchas to fill out, just close the software and wait 10 minutes to reopen it and continue your work. (This issue should have already been fixed now with the latest updates to the tool.)
Because when old users like me purchased the product licencse 2 types of options were existing USD 97 for the license fee and then USD 27 per month for using platinum feature and second option was USD 297 for lifetime purcahse.News users are exposed to new pricing structure and have the benefit of no one time license fee (USD 97) but directly they can use the software @ USD 37.
TIP: A really good strategy for increasing your search engine rankings (and maybe even getting a featured snippet), is to pick a number of popular questions, and answer them in your content. You can do this in the form of a ‘Question & Answer’ section or maybe ‘FAQs’. Just pick half a dozen or so questions, and list them, together with a short answer.
In a nutshell, Long Tail Pro helps you quickly find keywords in bulk based on a seed keyword that you input.  In addition to returning hundreds of related keywords, the tool also shows search volume (monthly search volume), advertiser bid, number of words, rank value, and my favorite Keyword Competitiveness (helps you judge the competition and keyword difficulty).
