Google has intensified efforts to combat manipulation of its AI-powered search systems, updating its spam policies to target attempts to influence generative AI responses appearing in Google Search.
The policy revision, introduced amid the rapid expansion of AI-generated search summaries, explicitly prohibits tactics designed to manipulate responses produced by tools such as AI Overviews and AI Mode. The move signals Google’s growing concern over a new wave of search-engine manipulation techniques emerging alongside generative artificial intelligence.
Under the updated rules, Google said spam policies now apply to content and practices intended to “manipulate generative AI responses in Search,” broadening enforcement beyond traditional ranking abuse.
The development comes as marketers, publishers, and SEO firms increasingly compete for visibility inside AI-generated answers that appear directly above conventional search results.
Industry analysts describe the phenomenon as “Generative Engine Optimisation” (GEO), a new branch of search optimisation aimed at influencing how AI systems summarise and recommend information.
“This is the next evolution of spam,” digital marketing analyst Nate Tower said in commentary on the policy shift. “Instead of manipulating search rankings alone, actors are now trying to manipulate what AI itself says.”
Google has not banned AI-generated content outright, but the company reiterated that automation used primarily to manipulate search visibility violates its guidelines.
“Using automation, including AI, to generate content with the primary purpose of manipulating ranking in search results is a violation of our spam policies,” Google previously stated in official search guidance.
The company’s latest move follows mounting concerns over “recommendation poisoning,” a practice in which websites are deliberately engineered to influence AI-generated answers. Tactics reportedly include mass-producing optimised articles, embedding hidden prompts for AI crawlers, and creating repetitive content tailored for machine-learning systems.

The issue gained wider attention after experiments demonstrated how AI-generated search responses could be influenced through coordinated content strategies. In one widely discussed case, a journalist reportedly manipulated AI search outputs to describe him as the “best hot dog-eating tech journalist.”
Researchers and digital media analysts warn that AI-generated summaries are becoming increasingly influential in shaping online information consumption. Studies examining AI overviews found that generative search systems often cite sources differently from traditional rankings, potentially reshaping competition for online visibility.
The shift also carries significant implications for publishers, many of whom fear declining web traffic as users increasingly rely on AI-generated summaries instead of clicking through to original sources.
SEO consultants say the updated policy indicates Google is preparing for a long-term battle against AI-driven spam and manipulation.
“Automation is not the issue. Manipulation is,” SEO consultant Jeremy Wilbur wrote in response to the changes.
Google has spent years combating tactics such as keyword stuffing, link schemes, and spamdexing designed to game traditional search rankings. Analysts say generative AI has opened a new front in that conflict, forcing search companies to adapt enforcement strategies to rapidly evolving AI systems.
Despite the crackdown, experts expect attempts to influence AI-generated search responses to continue growing as businesses seek greater prominence inside conversational search tools.
Google said its focus remains on surfacing “helpful, reliable, people-first content” regardless of whether material is produced by humans or AI systems.
