Google announced the launch of the campaign bid simulator in AdWords. This is something of an extension of the bid simulator launched a few years ago. Previously, the bid simulator worked at the keyword and ad group level, but with the new launch, you can access it at the campaign level.

It’s available in the Opportunities tab in AdWords, and lets you view bid changes (in aggregate) and model changes, “even when keywords or ad groups might not have enough data for this on their own,” according to AdWords Product manager Sheridan Kates.

“See what might happen if you increased or decreased all your bids by a specific percentage (10%, for example),” says Kates, listing the functions. “See whether you may need to increase your campaign budget to ensure it doesn’t become limited by budget at the new bid value.”

With the feature, you can also see what would happen if you changed all your bids to a single value.

From the campaign bid simulator, you can download bid simulation data (at the account or campaign level) and a file (compatible with AdWords Editor) with bid amounts at the simulated level, and the ad groups/keywords where they should be applied, according to Google.
