Search-based Keyword Tool provides keyword ideas

The Search-based Keyword Tool generates keyword and landing page ideas highly relevant and specific to your website. In doing so, the tool helps you identify additional advertising opportunities that aren't currently being used in your AdWords ad campaigns. The tool goes one step further by tailoring the keywords and other data (such as the amount of competition for the keyword, the suggested bid, and more) based on your language or country/territory settings.
