To use bid simulations, the campaign must meet the following requirements:
- You must have an established criterion, ad group, or campaign to provide the system with baseline information from which to generate predictions.
- The account must not be a test account. Bid simulations are based on past performance; since test accounts don't serve ads, they have no performance history.
Additionally, bid simulations work with Search Network-only campaigns, Display Network-only campaigns, Shopping campaigns, and Hotel campaigns. For Search Network with Display Select, only information pertaining to the Search Network portion of a campaign is returned.
