已集成AdMob的iOS应用迁移至其他账号的相关问题咨询

Let’s break down each of your questions clearly, based on hands-on experience working with AdMob for iOS apps:

1. How to migrate an iOS app with integrated AdMob Banner to another account? #

Here’s a reliable step-by-step workflow:

• First, log into your new AdMob account and create a new app entry using the exact same Bundle Identifier as your existing app—AdMob uses this ID to tie to iOS apps, so matching it is critical.
• Create a new Banner ad unit in the new app entry, and save the new ad unit ID somewhere easy to reference.
• In your iOS project:
  • Replace every instance of the old ad unit ID with the new one in your code (where you initialize the Banner ad).
  • Update the GADApplicationIdentifier value in your Info.plist file to match the app ID from your new AdMob account (you can find this in the new app’s settings page).
• Test the updated build thoroughly to confirm ads load correctly with the new credentials.
• Once you’ve verified everything works, push the updated app to the App Store.
• Finally, mark the old app entry in your original AdMob account as "Archived" or stop ad serving to avoid accidental overlap.

2. Will replacing old ad units with new ones from the new account cause issues? #

If done properly, this shouldn’t lead to major problems, but keep these points in mind:

• Temporary fill rate fluctuations: When you first switch to new ad units, AdMob’s system needs time to index the new units and start serving relevant ads. You might see lower fill rates or slower load times for the first few hours—this is normal and will resolve on its own.
• Never mix old and new units: Don’t use ad units from both accounts in the same app build. This can trigger policy flags for duplicate ad serving, which could lead to account restrictions.
• Double-check unit status: Make sure your new ad units are set to "Active" in the new AdMob account before pushing the update. Inactive units won’t serve ads at all.

3. Will AdMob's bots flag fraud based on Bundle Identifier matching? #

No, legitimate migrations using the same Bundle Identifier won’t trigger fraud alerts—AdMob understands that apps can be transferred between accounts (e.g., company reorgs, developer account changes). That said, avoid this key pitfall:

• Don’t run ads from both accounts simultaneously: If your old app entry is still serving ads while the new one is live, AdMob might flag this as duplicate traffic or unauthorized ad serving. Always stop ad serving in the old account after the updated app with new units is live and confirmed working.
• If you do get a false positive alert, submit an appeal through the AdMob dashboard, explain that you’re migrating the app to a new account, and provide any relevant documentation (like developer account transfer receipts) to back up your case.
