Advertisers are no longer using AI as a campaign add-on. They’re integrating it across the entire media lifecycle, from planning and creative to optimization and compliance. This brings us to our next question: Does AI in advertising drive any measurable impact yet?
The answer is a definite yes!
What is the ROI of using AI in optimizing advertising campaigns?
Advertisers who integrate AI into their creative and campaign strategies are enjoying quicker results, more effective campaigns, and a stronger connection with their audiences.
Based on the stats from Microsoft Advertising, the ROI from different campaigns is as follows:
- Responsive search ads: 1.5x better click-through rates in Performance Max (PMax) campaigns, and another 1.7x CTR improvements in PMax campaigns with the influence of Copilot.
- Multimedia ads: 2.3x better click-through rates in Performance Max (PMax) campaigns, and another 2.8x CTR improvements in PMax campaigns with the influence of Copilot.
- Shopping ads: 1.1x better click-through rates in Performance Max (PMax) campaigns, and another 2.6x CTR improvements in PMax campaigns with the influence of Copilot.
What are PMax campaigns?
PMax campaigns are goal-based Google Ads campaigns that use machine learning to find converting customers across all of Google’s inventory, including Search, YouTube, Display, Discover, Gmail, and Maps, from a single campaign.
Nielsen shares some key findings related to ROI from AI in advertising. The report suggests:
- Video campaigns on YouTube, powered by Google AI, show a 17% higher return on ad spend than manual campaigns.
- Adding Google AI Demand Gen to Search and Performance Max campaigns increases ROAS by 10% and sales effectiveness by 12% versus campaigns without Demand Gen.
- Google’s AI-powered Performance Max achieves 8% higher returns on ad spend and 10% higher sales effectiveness compared to Search-only strategies.
- Google’s AI-powered Broad Match for Search campaigns achieves a 15% higher ROAS and a 10% higher sales effectiveness compared to other keyword match type strategies.
AI-driven campaigns outperform human-managed ones because they merge creative intelligence (AI-generated assets) with predictive precision (machine learning models). It turns every impression into a learning loop that compounds ROI over time.

How marketers use AI in different forms of advertising
Here’s a statistical overview of AI usage in different forms of advertising, giving you a deeper understanding of the impact of AI on each type:
AI in programmatic advertising
In 2023, 81% of worldwide digital ad spending was conducted via programmatic channels, and this share continues to grow.
If we get a little specific, when purchasing connected TV (CTV) programmatically, 41% of buyers think it will lead to a better return on investment and ad spend, and 35% anticipate it will be easier to scale up. Overall, programmatic transactions account for approximately 85% of CTV purchases.
AI in social media advertising
Social media ad platforms have heavily integrated AI to improve campaign results. For example, Meta’s Advantage+ suite automates audience targeting, placements, and creative optimization using machine learning. Meta claims that advertisers using Advantage+ Audience targeting see up to 28% lower CPC and 7% lower cost per conversion versus manual Facebook targeting.
In a separate study, when Meta’s AI background image generator was used in ads, it led to an 11% average lift in click-through rate for those campaigns.
AI in video advertising
The IAB’s 2025 study found 86% of digital video advertisers are now using or plan to use generative AI for video ad creative development.
Advertisers predict that by 2026, 40% of all ad content (across formats) will be AI-generated in some form.
AI in search advertising
Search advertising has been transformed by AI, visibly through Google’s Performance Max campaigns. As of Q4 2024, Performance Max accounted for 69% of Google Shopping ad spend for retail advertisers, effectively taking over from traditional Shopping campaigns.
