Google’s Keyword Tool can help you build a base keyword list for your PPC campaigns, but it leaves the majority of your potential keywords in the shadows.

The Google Keyword Annualizer is an Excel spreadsheet tool (not connected with Google, AdWords, Microsoft or Excel) that can be used along with the Google AdWords Keyword Tool’s data export. By importing the data, the spreadsheet automatically calculates annualized local search demand numbers, allowing the data to be resorted based on the annualized calculation.

The Google Keyword Tool can help you at this bare bones stage of your process, establishing some very general terms surrounding your main target phrases that you’ve come up with, possibly even helping you think of a few outside-of-the-box terms you might not have originally thought of.Google’s Keyword Tool bases its results on popular keywords from across the globe, instead of personalized keyword searches from your actual site data like WordStream, this leaves the vast majority of keywords that could be useful to you on the sidelines.
