Because someone who is looking for something that specific is probably a much more qualified searcher for your product or service (presuming you're in the blogging space) than someone looking for something really generic. And because long-tail keywords tend to be more specific, it's usually easier to tell what people who search for those keywords are really looking for. Someone searching for the head term "blogging," on the other hand, could be searching it for a whole host of reasons unrelated to your business.
Provides links to price estimate tools from Google AdWords. That Google AdWords tool showed the necessary bid to rank #1 for 85% of queries, and roughly how much traffic you could expect AdWords to send you based on that bid price and ad position, though, as mentioned above, Google has obfuscated their data in their interface for everyone but longtime AdWords advertisers.

As a new customer trying to evaluate the software, I asked if my trial period could be extended once this fundamental issue was fixed, on the basis I couldn’t actually evaluate its requirements against my criteria.

If you are somewhat new to this whole ‘make money online’ thing – then surely the cost of Long Tail Pro is a major factor for why you haven’t purchased it yet. Believe me – I know! When I first started out – I refused to pay for anything at all. I did everything the free way. I tried doing all of my keyword research with the free tool that Google provides – and my keyword research efforts were terrible! You know how I know? Because my sites weren’t getting any traffic and I wasn’t making any money.
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).
