Last week at the SEW Blog, I reported that Google that on July 1st, Google will be adding a pricing model to the Google AdWords API program. This opens the Google AdWords API up officially towards commercial use. The news has traveled around the forums enough, while I was away. We now have a thread at WebmasterWorld and Search Engine Watch Forums.
The folks over at WebmasterWorld are not too happy with the return on investment Google is offering here. One Webmaster estimates "1,500,000 @ 25c/1000 = $375 would be the monthly cost for us if we were regularly using all of our quota." But it is important to keep in mind, that Google may not be charging a fee to everyone. In fact, I believe this fee will only be applied to bid management tools that want to use the tool outside of direct big management for themselves and within commercial reasons.
