Keyword Combination Tool
Looking to build combinations of keywords without a messing with concatenation and massive and error-filled find-and-replace jobs? This quick tool lets you dump in keyword components to build all combinations of phrases, with a short list of changeable parameters to let you use it as you need it. Nothing mind blowing, but it’s quick, easy, and useful (and better than Excel).

Yahoo! Search Engine
Yahoo!’s actual search engine itself can sometimes be handy to find related keyword verticals that are somewhat tangential to the list you’re working on. While some keyword tools are handy more for depth or breadth within a vertical, it’s nice sometimes to get a looser semantic sense and see what kind of other areas you might be forgetting, that might be worth targeting.

Demographics Prediction Tool
Not an essential tool, but we’re talking nifty, right? This tool lets you pop in a keyword and get some quick rough demographic expectations. While this tool can be useful beyond pay-per-click, it’s handy to know for whom to target your ad text, and offers valuable information in deciding whether to bid on a particular keyword or not.

If you’re looking to test and compare two different PPC ads, this tool can help you understand what’s going well and what’s not, as far as click through rate, what’s needed for conversions, and more. It even lets you know once you’ve reached a minimum test sample size, and lets you calibrate your results based on the confidence you need in their accuracy.
