Google has introduced a bid adjustment simulator for mobile bids in AdWords, as well as a new first-page bid estimate.

The mobile bid adjustment simulator shows how changing a mobile bid adjustment could have potentially affected impressions, clicks and spend over the previous seven days. The simulator will show estimated impact for both mobile bid adjustment increases and decreases.

You’ll find the mobile bid adjustment simulator from the Devices section under the Settings tab in a campaign. Be sure the Bid Adj. the column is activated. You’ll see the bid simulator icon in that column, below your bid adjustment.

Fine-print note: Keep in mind that because this simulator is only available at the campaign level, “If you apply any bid adjustment changes from the simulator, your ad group adjustments will be overwritten.”

First Position Estimates

Google has also added first position bid estimates to complement the existing first page estimates and top-of-page estimates. The estimate shows the bid you’ll likely need for your ad to be shown in position one at the top of the first page of results.

Bid estimates are relative to the device targeting in your campaign. If you’re running a mobile campaign, the bid estimate will reflect what’s needed to meet the placement threshold on mobile devices.

Both features are now available to all advertisers.
