The Future of Search Monetization: Ads in AI Answers (2025)

Updated on 2025-09-10

Change‑log: Initial publication with first‑party confirmations for Google AI Overviews/AI Mode ads and Microsoft Copilot chat ads; added Perplexity ad experiments and publisher program references; noted unknowns around Microsoft chat labeling.

TL;DR

AI answers are becoming premium real estate. Google is placing Search and Shopping ads in AI Overviews/AI Mode with clear “Sponsored” labels and staged market expansion in 2025, while Microsoft enables ad delivery inside Copilot chat via Microsoft Advertising and Performance Max. Perplexity is experimenting with sponsored follow‑ups and side placements. Marketers should plan distinct budgets, creative, and measurement for AI answer surfaces—and track both paid and organic presence together.

What changed: from blue links to blended answers

Across 2024–2025, the biggest shift in search monetization is that ads are moving into AI‑generated answer blocks and conversational interfaces. Google confirms that Search and Shopping ads can appear within AI Overviews (and, where relevant, in AI Mode) with a clear “Sponsored” label and staged global expansion beyond the U.S. during 2025, sourced from existing campaigns like Search and Performance Max, as detailed in the 2025 Google Ads updates and help center documentation (Google Ads blog: “New ways AI in Search helps your business,” 2025 and Google Ads Help on AI Overviews/Mode ads, 2025).

Microsoft, meanwhile, has been integrating ad experiences into Copilot chat since 2024, extending familiar formats and automation via Microsoft Advertising and Performance Max. Microsoft highlights creative assistance and performance anecdotes for multimedia and product ads within its October 2024 and April 2025 posts (Microsoft Advertising: transforming audience engagement with generative AI, Oct 2024 and AI in action — five insights, Apr 2025).

Perplexity (a smaller but fast‑moving AI answer engine) began testing ads as sponsored follow‑ups and side placements in the U.S., while committing to privacy assurances and neutral answers, per its 2024–2025 blog communications (Perplexity: why we’re experimenting with advertising). As of mid‑2025, OpenAI has not announced ads inside ChatGPT or SearchGPT; monetization remains through subscriptions and partnerships.

What’s live now (and what’s still evolving)

Google
- Ads appear in and around AI Overviews and may integrate into AI Mode responses where relevant, using existing Search, Shopping, and Performance Max inventory; all are clearly labeled “Sponsored,” per 2025 first‑party materials (Google Ads blog, 2025; Google Ads Help, 2025).
- Initial availability emphasized the U.S. (mobile first), with ongoing 2025 expansion to select English‑language markets, as signposted in late‑2024 and 2025 Google posts (Google Ads blog on AI Overviews ads, Nov 2024).
Microsoft
- Microsoft Advertising routes ads into Copilot chat via existing formats and Performance Max automation; Microsoft publishes performance anecdotes for multimedia/product ads across 2024–2025 (Microsoft Advertising Oct 2024; Apr 2025). Specific public wording for in‑chat ad labeling (“Ad” vs “Sponsored”) is not clearly documented in first‑party posts; treat as unspecified.
Perplexity
- Ads appear as sponsored follow‑ups and side placements in the U.S., with dedicated statements on labeling philosophy and privacy (Perplexity ad experiment). Perplexity also introduced a Publishers Program with revenue sharing tied to related questions where publisher content is referenced (Perplexity Publishers Program).

How ad delivery and labeling work in AI contexts

Relevance and conversation state
- Google indicates ads are eligible when relevant to the user’s query and to the AI Overview’s information, implying a combined intent/context match for delivery (Google Marketing Live/Ads framing, 2025).
Eligible campaigns and formats
- Google: Search and Shopping ads sourced from existing Search/Performance Max campaigns; placements can appear above, within, or below AI Overviews, and in AI Mode where relevant (Google Ads blog, 2025).
- Microsoft: Extend search/text, shopping/product, and multimedia ads into Copilot chat via Microsoft Advertising and Performance Max, per 2024–2025 posts (Microsoft Oct 2024 update).
Labeling and transparency
- Google states ads remain clearly labeled “Sponsored” in AI Overviews/Mode (Google Ads blog, 2025).
- Microsoft has not published explicit in‑chat label phrasing in the reviewed posts; confirm via UI or Microsoft guidance as your teams test.
Policy and controls
- Google provides help‑center guidance on eligibility, controls, and reporting for AI Overviews/AI Mode ( Google Ads Help: Show ads in AI Overviews and AI Mode).

Why this matters: attention, economics, and fewer clicks

AI answer blocks concentrate attention and compress click paths. As summarization grows, some traditional SERP clicks shift into micro‑interactions (expands, tooltips, carousels) or direct actions. This dynamic positions AI answer ads as premium inventory where intent density and message relevance carry outsized weight. Expect early volatility in volume and CPCs as inventory scales and targeting/refinement improves.

A measurement stack for AI answer surfaces

Traditional last‑click analysis will miss value created within compressed AI interfaces. Consider adding:

AI Surface Engagement: expand/collapse interactions, carousel swipes, and time‑in‑panel (where instrumentable).
View‑Through Conversions: modeled influence when users engage with an answer but don’t click.
Assisted Revenue and Branded Search Lift: triangulate downstream effects after exposures in AI answers.
AI Citation Share of Voice: how often your brand is cited within AI responses vs competitors.
Sentiment in AI Answers: track tone/stance when your brand is mentioned.
Inventory Availability and Eligibility Rate: how often your eligible queries actually surface AI answer ads.

Platform reporting for AI placements is evolving. Google emphasizes using existing campaign reporting and “AI Essentials” while expanding controls (Google Ads blog, 2025 and Google Ads Help, 2025). Microsoft highlights network‑wide reporting and Performance Max automation; chat‑specific interaction metrics are less detailed in public materials as of 2024–2025 (Microsoft Oct 2024).

Dual‑track visibility: paid + organic playbook

Performance marketers (SEM)
- Create an “AI Answers” segment with distinct budgets and negatives.
- Build creative for summaries/chat: crisp problem‑solution lines, clear promos/pricing, structured assets.
- Cluster testing around high‑intent queries (shopping, local, services) where AI Overviews commonly appear.
- Start with conservative bid caps; scale on measured incremental lift.
SEO and content leads
- Optimize pages for inclusion and prominent citations in AI answers: authoritative copy, concise answer sections, fresh pricing/availability, and updated schema.
- Track where AI answers appear and whether your domain is credited; iterate content to win citations.
Brand and e‑commerce managers
- Ensure product feeds and local listings are pristine and policy‑compliant, especially for Shopping/Local surfaces.
- Align landing experiences with conversation context (FAQs, comparisons, assisted checkout/returns info).
Agencies and analytics teams
- Instrument micro‑interactions; design geo/keyword holdouts to estimate incremental lift.
- Report AI answer share‑of‑voice and sentiment alongside paid outcomes for a holistic view.

A crawl–walk–run testing roadmap

Crawl
- Confirm AI Overviews/Mode availability by market and language; prioritize U.S. if applicable.
- Identify 50–100 high‑intent queries with frequent AI answers; map eligible campaigns (Search, Shopping, PMax).
- Ship concise creative variants tailored to summaries/chat; set conservative daily caps and bid limits.
- Instrument analytics for micro‑interactions where possible; set up branded search lift tracking.
Walk
- Expand to adjacent query clusters and new geos where AI placements are confirmed.
- Introduce structured offer testing (pricing, promos, value props) and asset combinations.
- Launch holdout groups (geo or keyword) to model incremental lift and view‑through effects.
- Layer organic efforts to win citations on the same topics; compare paid+organic blended impact.
Run
- Scale budgets to proven clusters; add seasonal/promo calendars.
- Explore multimedia/product showcases where supported (especially in Microsoft ecosystems with PMax automation per 2024–2025 updates).
- Build an executive dashboard: AI surface engagement, citation share, sentiment, assisted revenue, and incrementality model outputs.

What to watch next (clearly marked as evolving)

Sponsored actions and agentic flows: Hypothesis that users may book, buy, or start support workflows directly from AI answers; any such formats will require clear labels and consumer safeguards.
Commerce/affiliate modules inside answers: Expect more structured product/price integrations. Google Merchant Center continues to evolve attributes and disclosures for AI‑generated content in product feeds (Merchant Center Help on AI‑generated attributes, 2025).
Publisher revenue models: Perplexity’s Publishers Program includes revenue sharing on related questions when publisher content is referenced (Perplexity Publishers Program). Broader programs from larger platforms are not publicly announced; keep this as a watch item.
Labeling and policy updates: Continue to verify how platforms label in‑answer ads. For Google, “Sponsored” labeling in AI answers is stated in 2025 materials; for Microsoft, public phrasing remains unspecified. Expect regional ad‑policy nuances to evolve.

Practical next steps for leaders

Establish an “AI Answers” line item in your media plan and an owner across SEM/SEO.
Start with one or two markets where availability is confirmed, then expand.
Instrument micro‑interactions and build a monthly change‑log; re‑validate policies and availability quarterly.
Hold regular reviews to align paid and organic tactics on the same answer surfaces.
