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.
I hope it’s easy enough for you to clearly see how pretty much any website page or blog post can be slightly modified in order to get optimized around a certain keyword. For the Busy Budgeter example – Rosemarie could easily write a brand new article – or change the title of an existing article that is already written on a similar topic, add some subheadings and a few paragraphs and have it optimized for this really low competition keyword. A keyword like this will likely bring in new visitors month after month – and Rosemarie could direct readers of that article to some of her ‘make money online’ tutorials that we already know are very profitable for her!
Long Tail Pro is a keyword research tool that helps you quickly find low competition keywords for your website.  In particular, the tool is built for people doing SEO (search engine optimization) as opposed to people doing paid ads (Google Adwords PPC).  I'm sure there are some advertisers that use the tool for paid ad keyword research, but the tool was built for SEO keyword research.
