Back with my fourth SEO related Black Friday deal. Long Tail Pro is one of the best keyword tools and an absolute no brainer at this price. I am not in a position to afford Long Tail Platinum edition but that is also on sale. I am pretty sure you can try Platinum for a month for $1 if you own LTP normal version, at any time.
Also comes with 60 day money back guarantee. The creator of this software has a website and a podcast, he also just launched a training program
http://www.longtailuniversity.com/ I have seen sometimes they offer the university course for half price - $99.
You can google around to find out more if you don't know about this app, but it is pretty much the gold standard for keyword research according to the research that I have done into digital marketing. Much more funtionality than just using the google keyword planner, and a lot cheaper than Moz Pro (which offers different features, I haven't used both so I can't compare)
So the platinum is $297 for life?
