Google just showed its hand. During the Q4 2025 earnings call, the company revealed that AI Mode queries are 3x longer than traditional searches, daily usage per user has doubled since launch, and they’re already testing ads below AI responses.
This isn’t a future prediction. It’s happening now.
What Google Actually Said
Alphabet reported $63 billion in Search revenue for Q4 — up 17% year-over-year, the fastest growth of 2025. CEO Sundar Pichai attributed the acceleration directly to AI features.
Chief Business Officer Philipp Schindler dropped the key detail: Google is “in the early stages of experimenting with AI Mode monetization, like testing ads below the AI response, with more underway.”
He also announced Direct Offers — a pilot that lets advertisers show exclusive deals to shoppers “ready to buy, directly in AI Mode.” Checkout from within AI Mode is coming too.
The logic is straightforward: longer queries = more intent signals = better ad targeting = more inventory that didn’t exist before. Schindler said Gemini’s understanding of intent “has increased our ability to deliver ads on longer, more complex searches that were previously challenging to monetize.”
How AI Mode Ads Actually Work
Here’s what marketers need to know right now:
No new campaign type required. AI Mode ads pull from your existing Search (broad match/dynamic), Shopping, and Performance Max campaigns. If you’re already running these, you may already be appearing in AI Mode without realizing it.
Context goes deeper. Google doesn’t just match your ad to a single query. In AI Mode, the system considers the entire conversation — follow-up questions, refinements, the full research journey — to decide when and where to show your ad.
Relevance bar is higher. Your landing page needs to actually match the nuanced intent of a conversational query, not just a keyword. Generic landing pages that worked for “best running shoes” may not cut it when the query is “I’m training for a half marathon in humid weather, what shoes have the best ventilation under $150?”
Placement differs from AI Overviews. In AI Overviews, ads appear above or below the AI box on a normal SERP. In AI Mode, ads are embedded within the conversational flow — a fundamentally different context.
It’s Not Just Google
Two days ago, ZDNet reported that ChatGPT is also launching ads. OpenAI is testing sponsored results within chat responses. Meanwhile, Google has reportedly told advertisers that ads are coming to Gemini (the standalone chatbot) in 2026.
The pattern is clear: every AI interface will monetize through contextual ads. The question isn’t whether, it’s when and how aggressively.
This means the skills marketers built for traditional SERP advertising — keyword targeting, ad copy optimization, landing page relevance — are about to get remixed for conversational contexts.
What Smart Marketers Should Do Now
1. Audit Your Broad Match and PMax Campaigns
Since AI Mode pulls from existing campaigns, check your Search Terms reports for longer, more conversational queries. If you’re seeing them, you’re already in AI Mode. Optimize accordingly.
2. Rethink Landing Pages for Conversational Intent
A user in AI Mode isn’t just searching — they’re researching. They’ve asked follow-ups, narrowed their criteria, and have specific context. Your landing page needs to meet that specificity. Think comparison pages, detailed guides, and FAQ-rich content over generic product pages.
3. Watch Your Organic Traffic Patterns
If AI Mode keeps users inside Google longer (which is exactly what the earnings data shows), organic click-through rates could compress further. Monitor your Search Console data for CTR changes, especially on informational queries.
4. Start Testing Direct Offers
If you’re in e-commerce, get on the Direct Offers pilot waitlist. Showing exclusive deals to high-intent users inside an AI conversation is a different beast than a standard Shopping ad — the conversion potential is significant.
5. Track AI Mode Separately
Just like you should be monitoring Discover traffic separately from regular Search, start segmenting any AI Mode performance data you can get from your Google Ads account.
The Bigger Picture
Google is betting that AI search is additive, not cannibalistic. The earnings data supports this so far — Search revenue grew faster as AI features expanded, not slower.
But for marketers, “additive” doesn’t mean “free.” It means:
- Paid teams need to understand a new ad surface with different rules
- SEO teams need to accept that some queries will never leave Google’s AI interface
- Content teams need to create assets that work in conversational contexts, not just traditional SERPs
The AI search era isn’t replacing the old game. It’s adding a new one on top. The marketers who learn both games win.
