Pay-per-click advertising services such as Google's AdWords, Yahoo and others allow advertisers to reach targeted prospects for just pennies apiece. Never before has it been possible to advertise so cheaply, quickly and effectively to such a broad audience.

But the keyword phrases that drive these services are priced based on a high-bidder strategy, and the most popular/common phrases are quickly bid up in price. The secret to getting low-priced clicks is to develop a comprehensive list of keyword phrases that other advertisers aren't bidding on.

The Permutator is a tool that quickly creates keyword phrases containing all possible combinations of your input keyword lists. Hundreds--even thousands--of keyword phrases. Phrases that haven't been bid on by your competitors. Phrases that are still available for the minimum bid price. Phrases that will bring targeted traffic to your website.

The Permutator is filled with the features you need to quickly and efficiently develop keyword phrase lists. Select from unquoted, double-quoted, square-bracketed and space-less output formats. The Permutator can also generate keyword phrases with built-in bid amounts and landing page URLs in the format used by Google's AdWords service. When you're done, copy your word list to the clipboard for easy pasting into your online account. Or, export to a file in simple list format or comma-separated-value (CSV) format.

The Permutator includes bonus tools to help you manage your PPC ad campaigns and to assess your results. The Ad Editor allows you to compose new ad text offline, while it enforces the size limits for several major PPC services. This makes it easy to test new ad concepts without logging in to your online accounts. Experienced advertisers know that it's all about the bottom line: Return on Investment (ROI). The ROI Calculator makes it easy to compute how your ad campaigns are performing relative to one another, or from month to month.
