Google announced on Google+ that added a new set of columns to your keywords report tabs that gives you a snapshot view for all of your keywords at the same time.
The snapshot view gives you estimates for clicks and cost as optional columns in the Keywords tab, letting you build this neat new report.
Here is a screen shot of that report:
The new Bid Simulator columns will show you the best estimates for the additional clicks you might have received (and their associated cost) in the last 7 days if you had bid at any of the following points:
-50% lower than your base bid
-50% higher than your base bid
-300% higher than your base bid
-At your top of page bid estimate
These points help show a general range of high to low values across a broad or diverse set of keywords in your account. At a glance, these new columns can highlight which keywords may have the biggest potential to drive additional, cost-effective, traffic to your sites. You can still generate a full Bid Simulator report to get more detailed information for specific keywords.
