Google AI Overview Ads are transforming paid search campaigns in 2025. Business owners and marketing leaders now face a reality where click-through rate (CTR) no longer accurately measures ad performance.
These AI-generated summaries answer user queries directly on search engine results pages (SERPs), often providing complete answers before users even consider clicking through to a website.
As a result, many traditional PPC strategies are becoming less effective, and metrics that once guided campaign decisions are losing relevance.
Advertisers must rethink their approach to stay competitive. This includes revisiting targeting strategies, revising ad creative, and reallocating budgets to ensure measurable ROI.
Top-performing brands are already experimenting with Performance Max campaigns, audience-based targeting, and AI-assisted ad copy to maintain visibility despite declining CTRs.
For example, Shopify has focused on brand authority to ensure AI Overviews reference their products, while Amazon leverages high-quality content and structured data to remain visible even in zero-click searches.
Marketing agencies like [A] Growth Agency play a critical role in helping businesses navigate these shifts.
By combining advanced AI insights, robust analytics, and growth-focused strategies, we can ensure campaigns are optimized not just for clicks but for influence, conversions, and long-term growth.
This article explores AI Overview Ads, their impact on PPC, performance benchmarks, and actionable strategies to maximize ROI.

Impact on CTR:

- AI Overview Ads now appear in 13% of searches.
Famous examples:
- Amazon adjusted its search ad campaigns for AI Overviews by focusing on brand authority.
- HubSpot shifted some budget to audience campaigns to compensate for lower CTR.
Advertisers must recognize that traditional paid search strategies are no longer sufficient in an AI-first search environment.

- News publishers experienced traffic drops of 80% due to AI summaries.
Businesses must adopt new KPIs such as impression-to-answer rate, assisted conversions, and cost per visible impression.
The “Request Competitive Quotes” Controversy
Google Local Services Ads now include a Request Competitive Quotes feature, allowing users to request quotes without visiting landing pages.
Implications:
- Increased lead volume but lower quality.
- Attribution becomes complex.
- Traditional CTR metrics become less relevant.
Questions for advertisers:
- How are leads qualified?

New Features That Actually Matter And Which To Ignore
Not all new Google Ads features improve ROI.
Focus on:

Ignore for now:
- Broad match expansions without intent filtering.

Strategic Shifts: How Top Performers Are Adapting
Businesses adapting successfully focus on brand visibility, data-driven targeting, and landing page optimization.
Key strategies:
- Strengthen brand signals to increase AI citations.
- Use first-party data for precision targeting.
- Improve UX and conversion funnels.
- Diversify channels across video, display, and discovery campaigns.
Famous examples:
- Amazon: By enhancing product descriptions, structured data, and FAQs, Amazon increased its presence in AI Overview Ads. This improved assisted conversions even when CTRs dropped, showing the power of optimizing for AI-driven search rather than relying solely on clicks. Their approach integrates AI-powered Google Ads, algorithmic ad placement, and machine learning bidding to maintain visibility across high-value queries.
- Adaptation Over Resistance: Leading brands demonstrate that resisting AI-driven search trends is less effective than adapting campaigns. Companies focusing on AI-integrated advertising, generative search ads, and automated campaign optimization can maintain ROI, optimize Google Ads conversion rates, and navigate the evolving landscape of search engine marketing evolution.
Adaptation, not resistance, is now critical for maintaining ROI in AI-driven search.

CTR alone no longer reflects true performance.
Critical new metrics:

Tools:
- GA4 for multi-channel tracking

- Server-side tracking
- Multi-touch or data-driven attribution
Thus, marketing agencies guide businesses in setting up reliable frameworks, ensuring campaigns reflect true impact on revenue.
How AI Overview Ads Affect Paid And Organic Synergy
Paid and organic search efforts now overlap significantly.
Best practices:
- Align SEO and PPC teams on keyword intent maps.

Key principles:
- Hook: immediately address query intent
- Value: concise explanation of benefits

- CTA: clear and actionable
Consequently, responsive search ads and AI-enhanced copywriting maximize performance in AI-driven placements.

The key insight is clear: in AI-first search, strategy, content authority, and ongoing optimization are far more important than traditional metrics.
Businesses that adapt their campaigns to this evolving landscape are better positioned to maintain brand presence, influence, and ROI even when fewer users click through from search results.
