Adwords Bulls-eye - You will notice that this is the only tool under the "Paid" section. That's because this is the only tool I use that isn't free. But it sure is worth the money I paid for it! Don't worry. Adwords bullseye is a one-time purchase and it's very affordable. However, Glenn Livingston gradually increases his prices on many of his products and services so if you are planning on getting this awesome tool, then I would suggest buying it sooner than later.
With Adwords Bulls-eye you use a combination of the Google Keyword Tool, the Google Traffic Estimator, and a very slick Excel spreadsheet to determine the single most important keyword for your product or service. Then you use that keyword to reveal the cluster of keywords you should be focusing on. After that you group this cluster of keywords into 6 to 12 tightly-themed ad groups in another spreadsheet. From there you can copy and paste them into your Google Adwords account.
