Paid distribution
Where can a business pay to appear while a customer is researching or deciding?
Direct answer
Paid search remains the commercial foundation. As of July 2026, ads are eligible inside Google's AI Overviews in 12 countries, Google has AI Mode ad formats in US testing, OpenAI is testing sponsored units in ChatGPT in the US, Microsoft serves ads in Copilot, and Perplexity's ad program is reported wound down. Every claim on this page is dated and sourced.

Paid search remains the foundation
Classic search ads are still where commercial intent is captured at scale, with mature auction mechanics, measurement and policy. Nothing in the answer-engine shift has replaced that yet; what has changed is where else placement can happen and what the same pages must now establish to be eligible.
Ads inside AI-mediated search
Google’s pattern so far extends existing campaigns into answer surfaces: ads appear within AI Overviews with no separate bidding, and the AI Mode formats announced in May 2026 follow the same approach. The operating consequence is unglamorous. Eligibility rides on the campaigns and pages you already run.
Answer-engine advertising beyond Google
OpenAI is testing labeled sponsored units in ChatGPT for US free-tier users. Microsoft serves ads and commerce surfaces in Copilot. Perplexity, the first pure answer engine to sell ads, is reported to have wound its program down. The matrix below carries the dated detail; the pattern worth keeping is that these surfaces open, scope and close faster than annual planning cycles.
Community and video environments
Before a direct query happens, research happens: in community threads, in video, in forums that answer engines now license and cite. Reddit is both a paid channel and, since its 2024 licensing deal with Google, a supply line into machine-composed answers. These environments shape which businesses get asked about by name.
Eligibility and sensitive categories
Every surface carries policy constraints, and they bind hardest in regulated and sensitive categories: health, finance, personal circumstances. A surface being generally available does not make a category eligible on it. Category-level verification belongs in the plan.

Measurement requirements
A new surface without measurement is a rumor with a budget. Before spend moves, the questions are mechanical: what identifier survives the click, what event can be observed, what outcome can be matched back. In assistant surfaces, identifiers often do not survive yet. Where they do not, the honest fallback is incrementality thinking. See Measurement.
Failure patterns
Budget follows habit
Spend allocated by channel tradition while the current surface map goes unread
Speculative inventory sold as real
Strategies built around ad products that are announcements, not availability
New surfaces without measurement
Testing placements with no way to know what they produce

Search, Shopping and Performance Max ads are eligible to appear within AI Overviews in English on mobile and desktop in 12 countries, and above or below AI Overviews in more than 200 markets, with no separate bidding for the placement.

Perplexity launched advertising in November 2024, stopped accepting new advertisers in October 2025, and is reported (early 2026) to have wound the program down in favor of subscriptions.
The launch is primary-sourced. The wind-down rests on reporting of an FT interview; Perplexity has not published its own announcement, so this claim is partly reported rather than confirmed.
FactModerate confidenceChecked 2026-07-14
Microsoft serves ads inside Copilot conversations, and in January 2026 announced Copilot Checkout and Brand Agents rolling out in the US.
The January 2026 announcement is primary and centers on commerce; the conversational ad formats themselves are documented by Microsoft's earlier posts and trade coverage.

Reddit signed a data-licensing deal with Google in February 2024, reported at roughly $60M per year, giving Google API access to Reddit content for AI training and Search.
One reason community threads surface prominently in research journeys. The dollar figure is reported, not disclosed.
ForecastModerate confidenceHorizon: 12–24 months from 2026-07Checked 2026-07-14
Paid placement will continue moving into AI answer surfaces, and eligibility will initially extend existing campaign types rather than introduce separately biddable inventory.
Google's AI Overviews placement already works this way, and announced AI Mode formats follow the same pattern. OpenAI and Microsoft are testing labeled units inside conversations.
