Have you ever wondered how many impressions or clicks you could have received if you had used a different maximum CPC bid? Until now, finding the right bid has typically involved a lot of trial and error.

The bid simulator, launched today, is a feature of the new AdWords interface that shows you the potential impact of your bid on your advertising results. While it can't predict the future, the bid simulator allows you to explore what could have happened if you had set different keyword-level bids.

Using data from the past seven days, the bid simulator re-calculates the number of impressions for which your ad could have shown had you chosen a different maximum CPC, how many clicks your ad could have gotten for those impressions and how much those clicks could have cost. The feature provides increased transparency into the AdWords auction and gives you the insight to make more informed bidding decisions to meet your advertising objectives.

This simulation data can help you figure out the trade-off between click volume and cost, enabling you to answer more confidently questions such as:
  • How can I increase traffic to my site without raising my costs too much?
  • For which keywords should I alter my spend?
As you use bid simulator, it's important to note that past performance does not guarantee future results. Additionally, simulations will only be provided if there is enough traffic on a given keyword to conduct a meaningful analysis. These simulations are currently available only for Google.com and the Google search network.

For more information, view the bid simulator video and visit our help center.

To see data from the bid simulator, go to the 'Keywords' tab in your AdWords account.

Then, click on the bid simulator icon in the Max. CPC column next to the bid of any keyword you could like to see data for.

In this example, you are seeing simulations for the keyword "search email."
