The rules of online search are changing

Artificial intelligence is changing one of the internet's most valuable currencies: visibility. For more than two decades, Google has served as the internet's primary gateway to information, directing billions of users to news organizations, businesses and websites through a ranked list of links. Companies invested heavily in search engine optimization, or SEO, to improve where their content appeared in search results, while publishers relied on search traffic to attract readers and advertising revenue. Generative artificial intelligence is changing that relationship by synthesizing information from multiple sources into a single response, reducing the need to visit external websites.

Evidence suggests the consequences are already emerging. A July 2026 SSRN working paper found Google's AI Overviews reduced clicks to external websites by 39.8% on searches where they appeared and increased zero-click searches by 34.5%. As AI assistants become another gateway to information, businesses are rethinking online visibility. Rather than competing only to rank first, organizations now seek to ensure their content becomes part of the AI-generated response.

From search engines to answer engines

The change begins with how people retrieve information online. Instead of entering a series of keywords and opening multiple websites, users can ask conversational questions and receive responses synthesized from numerous online sources. Google has integrated AI Overviews into Search, while platforms such as ChatGPT, Perplexity and Claude allow users to retrieve information without navigating a conventional list of search results.

That evolution is prompting businesses to look beyond traditional SEO toward answer engine optimization, or AEO. Rather than improving search rankings, AEO focuses on increasing the likelihood that an organization's information is cited within AI-generated responses.

As AI systems synthesize information from multiple sources before generating a response, success depends not only on ranking prominently in search results but also on publishing authoritative, well-organized information that AI systems consider reliable. The implications extend beyond marketing. Website traffic remains central to revenue and customer acquisition across industries. As AI answers reduce visits to external websites, businesses may need new ways to measure digital visibility.

Technology research and advisory firm Gartner argues organizations should optimize for both AI-driven and conventional search. In its July 2026 Consumer Search Survey, only about one-third of consumers said generative AI had become a genuine rival to traditional search engines.

Who captures the value?

At the center of the debate is a simple question. If AI systems answer users' questions without sending them to the websites that produced the underlying information, who captures the value of that content?

The SSRN paper provides some of the strongest evidence yet that AI search is already reducing publisher traffic. Researchers conducted a randomized field experiment involving more than 1,000 users who installed a browser extension that removed AI Overviews from Google Search. AI Overviews appeared in 41% of observed searches. When removed, outbound organic clicks increased from 0.37 to 0.62 per search, indicating AI Overviews reduced publisher traffic by nearly 40% for affected searches while increasing zero-click searches by 34.5%.

Researchers also found no measurable improvement in user satisfaction after exposure to AI Overviews and no evidence that AI summaries redirected users toward sponsored links or other Google-owned services. Instead, the primary substitution occurred between AI-generated answers and visits to external websites.

Publishers lose clicks, not necessarily users

Early evidence suggests AI-generated search is changing user behavior in ways that could have significant consequences for publishers and businesses that depend on search traffic.

A July 2025 analysis by the Pew Research Center found users were nearly half as likely to click on traditional search results when Google displayed an AI Overview. Analyzing more than 68,000 Google searches by 900 U.S. adults, researchers found users clicked a traditional search result in 8% of visits with an AI summary, compared with 15% without one. AI Overviews appeared in 18% of all searches and were most common for detailed queries, appearing in 53% of searches containing at least 10 words.

The findings are prompting organizations to reconsider how they measure digital success. Rather than focusing solely on rankings and click-through rates, businesses are placing greater emphasis on whether their content is referenced or cited within AI-generated responses. For publishers, the challenge is more fundamental. If readers obtain the information they need without leaving the search page, audience reach and advertising revenue become more difficult to sustain even when their reporting informs the answer itself.

Search becomes a competition issue

The implications extend beyond publishers and marketing departments. They are also becoming a question of competition policy.

On July 23, the European Commission fined Google €890 million, approximately $1 billion, for violating the European Union's Digital Markets Act by using its dominant position in search to favor its own services, including shopping, travel, games and translation. Regulators concluded Google displayed its own services more prominently while pushing rivals lower in search results, violating the bloc's digital competition rules.

Although the case does not concern AI Overviews directly, it highlights a broader issue as AI-generated search expands. Search engines are no longer simply organizing information. They are also determining which sources become part of the answers users receive.

That debate is already reaching regulators. The SSRN study notes that competition authorities in the United Kingdom have proposed allowing publishers to opt out of AI-generated summaries, while complaints involving AI Overviews have also been filed in Europe and Brazil. At issue is whether search platforms are capturing greater value from content produced by others while sending less traffic back to the websites that created it.

The implications extend well beyond media organizations. Across industries, success may depend not only on ranking highly in search results but also on becoming a trusted source for AI-generated answers.
