Fears of a long-predicted “Google Zero” scenario are intensifying as artificial intelligence reshapes the relationship between Google Search and the publishers that have historically depended on it for referral traffic.
According to a Goldman Sachs TMT note citing reporting from The Wall Street Journal, some publishers experienced traffic declines of more than 40% between mid-2025 and mid-2026, adding to concerns that Google is increasingly answering users’ questions directly rather than sending them to third-party websites.
The shift is creating a strategic dilemma for publishers: continue allowing Google’s crawlers to access their content and preserve traditional search visibility, or restrict access amid concerns that the same crawling infrastructure may also support AI products.
Publishers Face a Google Search and AI Trade-Off
For much of the internet’s history, publishers accepted Google’s crawling because appearing prominently in search results could generate substantial referral traffic.
Generative AI is challenging that arrangement.
Google has increasingly integrated AI-generated summaries and other answer-focused features into Search, potentially reducing the need for users to click through to external websites.
At the same time, publishers are increasingly focused on how their content is collected and used to develop or power AI systems.
The Goldman note highlights a particular concern around Google’s multi-purpose crawlers, which can serve functions extending beyond conventional search indexing. Publishers that want access to Google Search may therefore have limited ability to selectively restrict how Google interacts with their content without risking a loss of search visibility.
That dynamic has become a central point of tension as media companies seek greater control over valuable editorial material.
Major Publishers Consider Restricting Google Crawlers
According to the note, several prominent online platforms and publishers, including USA Today, Reddit, Politico and Reuters, are considering or preparing measures that could restrict Google’s access.
Such moves would represent a significant change in the balance of power between publishers and the search giant.
Historically, excluding Google crawlers carried an obvious cost: losing visibility in the dominant search engine could sharply reduce audience reach and advertising revenue.
But if Google Search itself sends progressively less traffic to publishers, the economic calculation begins to change.
Publishers may become more willing to sacrifice some search exposure if they conclude that unrestricted crawling provides greater value to Google’s AI ecosystem than the referral traffic they receive in return.
Cloudflare Could Accelerate the Shift
Cloudflare is also emerging as an important player in the dispute between content owners and AI companies.
According to the Goldman note, Cloudflare plans to begin blocking multi-purpose crawlers by default from mid-September unless website owners choose otherwise.
A default-blocking model could make it significantly easier for publishers to restrict automated access without individually configuring protections against every crawler.
If broadly adopted, such infrastructure-level controls could strengthen publishers’ negotiating position by making access to high-quality web content less automatic.
That could ultimately encourage more licensing agreements between AI companies and publishers rather than relying on the historically open crawling model of the web.
Is the ‘Google Zero’ Era Getting Closer?
“Google Zero” refers to a scenario in which Google continues to use information from across the web but sends little or no meaningful referral traffic back to the websites that produced it.
The concept has been discussed for years, but the expansion of AI-generated search answers has made the possibility more consequential for media businesses.
A decline of more than 40% in traffic for some publications does not mean Google Search has stopped generating referrals across the internet. However, the trend illustrates why publishers are reassessing a relationship that was once considered essential and largely non-negotiable.
The implications extend beyond news organizations. Review sites, reference publishers, independent blogs and other businesses built around organic search traffic could face similar pressure if users increasingly receive complete answers directly within search interfaces.
For Google, meanwhile, reduced access to publisher content could make it more difficult to maintain the breadth, freshness and quality of information available to both Search and AI systems.
