Soon, we'll be changing the Google AdWords keyword evaluation system to help give advertisers more control over keywords they find important.
From an API perspective, there is a new minCpc field in the Keyword object that you can use to determine how much to bid in order to keep a keyword active. Keyword statuses changed a bit in the AdWords online interface, but not in the API.
In addition, with the release of the rate sheet scheduled for Aug. 1, 2005, you should have more keyword stats operations available to adjust to these keyword evaluation changes. For more information on how the new keyword evaluation system impacts the AdWords API, please visit our help page.
