Amazon is exploring a hybrid search combining AI summaries with product listings. This is a strategic move to engage customers earlier in the buying journey—the "product discovery" phase—a role traditionally dominated by Google. This could increase user time on site, ad revenue, and direct purchases, effectively moving "up the funnel."

SEMrush data shows that search queries containing eight or more words have a sevenfold higher likelihood of triggering a Google AI Overview. This means marketers must shift from short keywords to long, human-toned questions, a strategy called "scenario marketing," to gain visibility in these AI-driven results.

Consumers use AI tools like ChatGPT for product discovery, receiving relevant brand recommendations they were previously unaware of. This lengthens the consideration phase, creating a new battleground for marketers in the middle of the funnel.

While familiar metrics like ROAS and CPC will persist, AI search advertising requires a new approach. Instead of focusing on discrete keywords, advertisers must broaden their strategy to target entire conversational contexts and semantic categories to capture richer user intent.

Google's Universal Commerce Protocol allows users to buy products or book demos directly in AI-powered search results. Marketing success is no longer about site clicks, but about influencing decisions and completing transactions within Google’s ecosystem, a fundamental change for all marketers.

When a specific brand search fails, users make longer, descriptive queries. AI search uses this context to suggest relevant competitors (e.g., Rag & Bone over Levi's), creating opportunities for challenger brands to win customers from established leaders.

Generative AI changes brand discovery from a budget-driven game to one based on relevance, credibility, and usefulness. This levels the playing field, allowing smaller, more agile brands to compete with larger incumbents who traditionally relied on massive ad budgets.

Unlike Google, which primarily handles discovery, AI models engage users in a Q&A process that guides them through consideration. This means when a user clicks through from an AI search, they are highly qualified and ready to convert, explaining the significantly higher conversion rates seen from this traffic source.

Google's VP of Search believes the core ad business is safe because for commercial queries, an AI summary doesn't replace the need to click a link to purchase an item. Furthermore, more descriptive AI-driven queries can lead to better-targeted, higher-value ads.
