New data reveals that Google’s AI-generated search summaries are devastating paid search performance. Studies show that paid click-through rates on queries with AI Overviews have dropped from 19.7% to just 6.34% – a 68% decline that is forcing advertisers to rethink their entire search strategy.
Meanwhile, Google has expanded AI Mode’s Canvas workspace to every US user and added checkout capability, signaling that AI-first search is here to stay.
The Numbers: Paid CTR in Freefall
The impact varies by query type, but the trend is consistent across categories. When Google shows an AI Overview above search results, users are getting their answer directly from the summary and skipping both organic and paid results entirely.
For informational queries, the damage is worst – organic traffic has dropped between 15% and 64% depending on the category. For commercial queries where users are actively looking to buy, the impact is smaller but still significant enough to blow up existing ROAS models.
This comes as nearly 800 million people per week now use ChatGPT alone to answer questions, compare options, and plan next steps. Add Google’s AI Mode, Perplexity, and Claude to the mix, and a massive chunk of search intent is being satisfied before users ever see an ad.
Google AI Mode Expands with Checkout
Google is not slowing down. AI Mode’s Canvas workspace – a visual, interactive search environment – is now available to all US users. The addition of checkout capability means users can research and buy products without ever leaving the AI experience.
For advertisers, this creates a paradox: Google is simultaneously reducing the effectiveness of traditional search ads while building new commerce experiences that it will eventually monetize. The question is how quickly Google introduces ad placements within AI Mode – and how much they will cost compared to traditional search ads.
Key Takeaways
- Paid CTR drops from 19.7% to 6.34% on queries with AI Overviews (68% decline)
- Organic traffic down 15-64% across categories with AI summaries
- 800M weekly ChatGPT users satisfying search intent outside Google
- Google AI Mode Canvas now available to all US users with checkout
- Traditional search ad models are being disrupted faster than expected
What This Means for Marketers
Diversify beyond search ads now. If paid search is your primary acquisition channel, the math is changing fast. Start shifting budget toward channels where AI is not yet eating into performance – email, partnerships, communities, and direct-to-consumer.
Optimize for AI citations. If users are getting answers from AI summaries, Make sure your brand is the one being cited. Structured data, authoritative content, and being referenced in AI training sources becomes the new SEO.
Watch AI Mode ad placements. Google will monetize AI Mode – it is inevitable. Early adopters who test these placements when they launch will have a significant advantage in cost and learning, similar to the early days of Shopping ads.
