While acknowledging the efficiency of AI in bidding and optimization, the manager notes that a Google representative stated 70 to 80 percent of advertising operations are now handled by AI. The core issue is that AI optimizes for the signals provided, such as clicks or shallow conversions, which may not align with actual business value. If bid amounts are too low, AI may learn to target easier, less valuable audiences rather than the intended customers, leading to wasted spend.\n\nThe manager highlights that high click-through rates do not guarantee sales, as users may click on mismatched ads. For example, AI might expand the keyword \"sweet snack\" to include ice cream or fruit, whereas humans would associate it with baked goods. The manager advocates for a hybrid approach: using AI for fine-tuning and speed, but keeping humans in control of defining what constitutes a \"good result\" and setting safety limits. In one instance, when the cost per conversion rose to 9,000 yen, the manager resisted increasing the budget and instead investigated automation changes and market conditions. The cost eventually returned to the 7,000 yen range without drastic changes, demonstrating the value of human judgment in maintaining focus and avoiding panic-driven decisions.","keyPoints":["Google representative says 70 to 80 percent of ad operations are now handled by AI.","AI may optimize for easy clicks rather than valuable customers if bid amounts are low.","Manager kept cost per conversion stable at 7,000 yen by resisting budget increases."],"whyItMatters":"As AI automation in advertising grows, advertisers risk losing control over strategic goals.
