Google AdWords has been testing a beta feature since late May known as “bid simulator.” The feature basically shows you how many impressions and how your ad position would look, if you increased or decreased your bid price. Here is a screen capture I grabbed from the reference guide on this new beta feature:
The feature looks pretty impressive and I think it would be useful for some advertisers. I am honestly surprised that I missed this when it first was being tested a few weeks ago. There is a considerable amount of stories on the feature, but I just found it today by way of forum coverage. I guess having a new baby girl distracted me enough to miss this news.
Postscript: A Google spokesperson sent me the following statement on this new feature:
As part of our ongoing commitment to innovation, Google constantly tests new tools to improve our AdWords product offering and provide additional benefit to our advertisers. We are currently testing a feature called “bid simulator,” which helps advertisers make informed and efficient bid management decisions by estimating the results they would have achieved using hypothetical bid values. This feature is currently in a limited beta with a small number of advertisers. We have no additional news to announce at this time regarding developments for Google AdWords.
