What is the core difference in functionality between the classic Gemini interface and the newer Yahoo Ad Manager concerning campaign budget allocation?

The core difference in functionality between the classic Gemini interface and the newer Yahoo Ad Manager concerning campaign budget allocation lies in the enhanced centralized budget management capabilities offered by Yahoo Ad Manager. In the classic Gemini interface, budget allocation was primarily managed at the campaign level, requiring individual budget adjustments for each campaign. Yahoo Ad Manager introduces features like 'Shared Budgets' (or similar centralized budget features, depending on specific updates) that allow you to allocate a single budget across multiple campaigns. This allows for more efficient distribution of spend based on real-time performance, automatically shifting budget to higher-performing campaigns. For example, in classic Gemini, if you had three campaigns and wanted to increase the budget for the best performing one, you'd manually adjust each campaign's budget. In Yahoo Ad Manager, with Shared Budgets, you could set an overall budget and the system would automatically allocate more spend to the best-performing campaign while limiting spend on underperforming ones. This automated budget optimization streamlines the budget management process and maximizes overall campaign performance. The Yahoo Ad Manager is more about centralized and automated budget optimization, which was less featured in the classic Gemini Interface.
