Gayet açık : Unfortunatley, the AdWords API isn't as open as you might think: It's meant for ad agencies managing large accounts, or software vendors who want to build ad management platforms. You need to apply to Google for an API key to gain access; they used to give them out to nearly anyone with an account, and it took about 14 days to process the application. However, Google has got very strict about their terms and conditions over the past 12 months, and to put it simply, you probably won't meet them if you're building an SEO tool; even if you apply to build a full platform, you'll need to wait six to ten weeks for approval as they've got a huge backlog of applications to process at the moment.
