We improved the allocation logic for the shared budget in campaigns.
This enhancement is expected to increase conversion rates and help control cost per acquisition (CPA) across all campaigns using shared budgets.

In campaigns with shared budgets, spending trends may change. After the release, check your campaign performance and consider adjusting budgets or bids if necessary.

To maximize the effectiveness of shared budgets, consider the following when setting them:

• Select campaigns with similar performance levels
• Keep campaigns consistent as either conversion-tracking or non-tracking.
