I just finished writing an Excel interface to the SEOmoz Linkscape API and I’m really excited about it. It’s the first step on my path to SEO domination!
Future plans include an interface to the Raven SEO API and Google Analytics API. Ultimately, I want it to read your mind and do everything you need it to do online to get better rankings for all of the sites you want. If you know of any API’s for that, please let me know.
