I used Raven before they added lots of adwords tools and I'll use them if they go. I still think it is one of the best value toolsets out there. I say this as I don't want people to think I'm knocking a great product. However hereis the main part of the mail that went out:
--- start ---
Raven received notice from Google late last week that we would lose access to its AdWords API. Without API access, Raven can't provide Google AdWords research, management and reporting to our customers. There's no short-term solution that will allow Raven to keep its AdWords API access and not affect other tools important to many of our customers.That's why, beginning at 11:59 p.m CST (GMT-5) on this Wednesday, Nov. 14,** Raven Internet Marketing Tools will no longer offer AdWords authentication, tools or reporting data.**First, I want to stress that your Google AdWords accounts and campaigns will not be affected. You can still log in to https://adwords.google.com to manage those accounts and campaigns. This change only affects Raven’s ability to sync your AdWords data in our platform.Second, I want to apologize. We know that this is more than an inconvenience to you. We’re urgently researching alternate data to integrate with Raven, but we don’t have specifics or a timetable to share yet.Since we will no longer be able to provide AdWords reports, I strongly suggest that you export or report any Google AdWords metrics before the cut-off date. For step-by-step instructions on how to download or report on your Google AdWords metrics to date, please see this article from our Knowledge Base.-- end --They then went on to list the exact parts that will be affected - tool by tool and their plan for tackling each.
The impact on keyword manager and serp tracker are bad for me (particularly as these are two areas that I think they do much better than seomoz). I hope that they will find alternative, credible, data sources for those.
