Google’s AI Mode Shifts Search Traffic Inside Its Own Ecosystem

Regulatory action – The European Union’s Digital Services Act (DSA) and the U.S. Federal Trade Commission’s (FTC) antitrust review both require online platforms to provide clear information about how automated content is generated and to avoid unfairly disadvantaging competitors.

What it requires – Companies must:

1. Disclose when an answer is produced by an AI system and identify the underlying data sources in a way that is understandable to the average user.
2. Offer users an easy mechanism to access the original sources rather than burying them in footnotes or “source chips.”
3. Ensure that any commercial arrangements influencing the ranking or presentation of AI‑generated content are transparent and do not constitute unlawful preferential treatment.
4. Provide a straightforward process for users to report inaccurate or harmful AI outputs, with a commitment to remediate within a defined timeframe (the DSA sets a 48‑hour window for high‑risk content).

Compliance timeline – Under the DSA, the disclosure obligations become enforceable on 1 November 2024. The FTC’s pending rulemaking on “AI‑driven search practices” is expected to be finalized by 30 June 2025, with a 90‑day compliance period thereafter.

How AI Mode Works

At Google I/O 2026, Search VP Liz Reid announced that AI Mode now serves more than one billion monthly users and that query volume is doubling each quarter. The feature appears as a separate tab in Chrome’s omnibox and as an “AI Mode” button on the Google.com search page. When a user asks a question, the system generates a prose answer and appends numbered citations that link to the original webpages.

Example Interaction

• User query: Why does Google Search suck now?
• AI Mode answer: You are definitely not imagining it. Users, tech critics, and researchers have documented a measurable decline in Google Search quality…
• Citations: Links to a blog post on seo2, a Medium article, a Reddit thread, and an economics essay.

While the citations are technically present, they are hidden behind a small footnote icon, reducing the likelihood that a user will click through to the source. Ahrefs reports that AI Overviews (the predecessor to AI Mode) have cut the average click‑through rate for top‑ranking pages from 34.5 % to 58 % lower over eight months.

Why This Matters for Regulators

Transparency

The DSA mandates “clear and concise” labeling of automated content. Google’s disclaimer – “AI can make mistakes, so double‑check responses” – is a generic warning that does not satisfy the requirement for a specific, prominently displayed notice.

Competition

By surfacing AI answers that summarize external content, Google reduces traffic to the original sites. This practice can be interpreted as a form of self‑preferencing, potentially violating the FTC’s standards against anti‑competitive conduct that harms rival publishers.

Data‑Protection

AI Mode relies on user‑level data (location, search history, device identifiers) to personalize answers. Under the GDPR, any processing that creates a profile for the purpose of delivering tailored content must be disclosed in the privacy notice, and users must be offered an opt‑out. Google’s current UI does not provide an obvious opt‑out for AI‑generated personalization.

Steps for Compliance

1. Prominent AI Disclosure – Add a banner or label at the top of the AI answer stating, “This answer was generated by Google’s AI model using the following sources.”
2. Visible Source List – Replace footnote icons with an expandable list that shows each source URL in plain text, allowing users to click directly.
3. Opt‑Out Mechanism – Include a toggle in the Chrome settings that disables AI Mode or limits personalization based on location and browsing history.
4. Audit of Commercial Influence – Conduct an internal audit to verify that no paid relationships affect which sources are cited, and publish the findings in a transparency report.
5. User Reporting Workflow – Implement a “Report inaccurate answer” button that logs the complaint, triggers a review within 48 hours, and notifies the user of the outcome.

Outlook

Google’s AI Mode represents a significant shift from traditional search, moving the platform from a “gateway to the web” to a “content generation hub.” While the technology offers convenience, regulators are likely to scrutinize the practice under both the DSA and upcoming FTC rules. Companies that adopt similar AI‑driven search features should proactively align their product designs with the transparency, competition, and data‑protection standards outlined above to avoid enforcement actions.
