The future of AI-powered search ads is here, and it's causing quite a stir! Google's AI Max, a groundbreaking tool for advertisers, has hit the market, but not everyone is convinced it's the game-changer it claims to be.
The Promise of AI Max: Revolutionizing Search Ads?
AI Max, launched in May, is a powerful suite of AI-driven tools designed to enhance search campaigns across Google's advertising platforms. It promises to match ads with relevant searches, even those not explicitly bid on, and customize ad copy based on user intent. With features like search term matching and URL optimization, AI Max aims to boost reach, improve performance, and save advertisers precious time.
But here's where it gets controversial: buyers are skeptical. Despite Google's claims, many advertisers are questioning whether AI Max can truly deliver on its promises.
The AI Overview and AI Mode Conundrum
Currently, AI Max is the only way for brands to reach AI Overview and AI Mode users with paid messaging. Google has been strategically placing ads above and below Overview summaries and within AI Mode results, but this placement is not yet advertiser-controlled. Instead, Google selects ads run through AI Max, almost like a selective lottery.
Google has already experimented with placing shopping and text ads below the first search response in AI Mode for desktop and mobile in the U.S. In the fourth quarter of 2025, they began integrating ads into the first response. If these placements become more accessible next year, they could be a game-changer for retailers, given the growing use of AI tools by shoppers.
The Black Friday Effect: AI Search Traffic Soars
According to estimates from media agency Wpromote's Polaris platform, AI search-driven traffic to retail sites surged by a staggering 850.7% during the Black Friday/Cyber Monday weekend. This highlights the potential impact of AI-powered search ads.
Agency Experiments: Mixed Results, Mixed Feelings
Agency media buyers have been testing AI Max since its launch, with varying outcomes. Some report improvements, while others suggest it falls short of expectations. A search practitioner, speaking anonymously, expressed skepticism: "It's not delivering what it's supposed to. I'm not seeing the intelligence in the AI yet."
A Google spokesperson defended AI Max, calling it their "fastest-growing AI-powered Search ads product." They emphasized the need for advertisers to set clear goals and utilize the full suite of features to allow AI Max to find new opportunities beyond standard keyword lists.
Indie agency Mediassociates tested AI Max with three clients, allocating 5-10% of their search budgets. Tim Lathrop, vp of platform digital at Mediassociates, said: "It's helpful for reach, but for performance-based clients, it's not proven effective yet."
Google claims non-retail brands activating AI Max in Search typically see a 14% increase in conversions with the same CPA as their usual search ads. However, Lathrop's team found the opposite, with traditional search campaigns outperforming AI Max in most cases.
Vitya Vijayan, global head of search and social at M&C Saatchi Performance, shared a similar experience. She found the feature generated broad or tangentially linked keywords, rendering them useless for clients. While lists of keywords to avoid are possible, this adds time and defeats the purpose of AI Max's automation.
Some buyers have opted to disable AI Max's AI creative features to regain control over keyword bidding and landing page selection. Sam Clarke, head of search at Crossmedia, explained: "Disabling the dynamic ad copy and landing page selection features has produced good results."
Not all experiences have been negative. Indie media shop Roast has been testing AI Max since September. Paid media account manager Patrick Kearney noted that clients with broader keyword campaigns didn't see significant improvements, but those with narrowly defined search queries found Google's search matching features useful.
"We've had mixed successes," Kearney added, highlighting the cautious approach they've taken with AI features.
Other practitioners praised AI Max's reporting capabilities, which make performance discussions with clients easier and allow agencies to demonstrate impact.
However, the mixed signals from testing have caused some agencies to step away from AI Max until significant improvements are made. Lathrop said: "Clients don't want to wait. We've had many clients say: let's move away from AI Max and come back to it."
With AI Modes, Overviews, and Gemini still relatively new, this reluctance may be short-lived. If paid ads within these environments become more accessible next year, brands and buyers might decide the potential rewards outweigh the risks and time investment.
"You have to be willing to let go of some control in certain cases," said Crossmedia's Clarke. "It's about finding the balance between value and hindrance."
The debate around AI Max's effectiveness continues, leaving advertisers with a choice: embrace the potential of AI-powered search ads or stick with traditional methods. What do you think? Is AI Max the future of search advertising, or is it just another tool in the ever-evolving digital marketing landscape?
