Google Ads Video Ads 2026: AI Resizing, Gemini Omni, and Rising CPCs

What Is New With Google Ads Video Ads in 2026?

The key change is that Google Ads is now using generative AI to automatically resize Performance Max video ads for different placements. This feature, rolling out in mid-2026, eliminates the need for advertisers to manually crop or reformat videos for YouTube, Discover, Gmail, and the Display Network. At the same time, Google has integrated its Gemini Omni video creation capabilities directly into the Google Ads interface, allowing advertisers to generate full video ads from text prompts or existing assets.

These updates arrive as new benchmark data from Rocking Web shows the average Google Ads CPC reached $5.26 across 23 industries in 2025, a 12.88% increase year-over-year. Conversion rates rose by 6.84% during the same period, driven largely by AI-powered campaign automation. For video specifically, YouTube TrueView in-stream ads average between $0.026 and $0.10 per view, with view rates as high as 66%.

Generative AI Video Resizing for Performance Max Campaigns

How the AI Resizing Works

The new generative AI resizing tool within Performance Max automatically adapts video ads to fit any placement. When an advertiser uploads a horizontal 16:9 video, the AI can crop, reposition, and generate new visual elements to create vertical, square, or other aspect ratio variants without manual effort.

Advertisers still retain control over the source video and can approve or reject AI-generated variants. The feature aims to reduce the time spent on creative production while ensuring ads look native across all Google properties.

Why This Matters for Advertisers

Performance Max campaigns have grown rapidly because they combine all Google ad inventory into a single campaign. A report from Search Engine Journal notes that Google has also launched new Search and AI Max experimentation tools, giving advertisers more ways to test and refine strategies. The video resizing feature addresses a long-standing pain point: creating multiple video formats for different placements.

However, the same benchmark report indicates that Performance Max campaigns show mixed results. While they deliver a 19% higher ROAS than social media platforms, they also come with rising costs and decreased advertiser control. Some advertisers report a "confession gap" — they feel pressured to praise Performance Max performance publicly while privately noting inconsistent results.

Gemini Omni Video Creation Comes to Google Ads

What Gemini Omni Does

Google is bringing Gemini Omni video creation directly into the Google Ads platform. This multimodal AI model can generate full video ads from a text description, a product URL, or existing images and text assets. Advertisers can describe the desired scene, style, and tone, and Gemini Omni produces a complete video ready for campaign use.

The integration means advertisers no longer need separate video editing software or external AI video tools. The feature is designed for small businesses and large brands alike, lowering the barrier to video ad creation.

Practical Implications

For ecommerce brands, this could be transformative. A seller who wants to promote a new product can type "Show the product being unboxed in a bright kitchen setting with upbeat music" and get a usable video within minutes. The tool also supports multiple languages and regions, automatically adjusting voiceover and text overlays.

Industry observers note that this move positions Google Ads as a complete creative and media buying platform, reducing reliance on third-party creative agencies.

Google Ads Benchmarks 2025–2026: CPCs Rise, Conversions Improve

Key Data Points

The comprehensive benchmark report from Rocking Web provides a detailed snapshot of Google Ads performance across industries. Here are the headline figures:

Metric	Value	Change (YoY)
Average CPC (all industries)	$5.26	+12.88%
Overall conversion rate	~4.23%	+6.84%
YouTube TrueView CPV	$0.026–$0.10	Stable
YouTube TrueView View Rate	Up to 66%	N/A
Performance Max ROAS vs. Social	19% higher	N/A

Industry Variation

The report breaks down CPCs by 23 industries. Legal, insurance, and technology tend to have the highest CPCs (often exceeding $10), while retail, ecommerce, and entertainment see lower averages. Video ads on YouTube remain the most cost-effective format, with cost-per-view far below typical display or search CPCs.

YouTube Video Ads: Still the Most Cost-Effective Format

Current Cost Benchmarks

YouTube video ads continue to offer strong value. TrueView in-stream skippable ads average between $0.026 and $0.10 per view, with view rates reaching 66% when targeting is optimized. Bumper ads (non-skippable, 6 seconds) typically cost slightly more per impression but offer high completion rates.

Best Practices for 2026

• Use skippable in-stream ads for brand awareness and consideration.
• Combine YouTube video ads with Performance Max to extend reach across Google properties.
• Leverage the new AI resizing tool to adapt YouTube-optimized horizontal videos for other placements.
• Test Gemini Omni-generated videos against professionally produced footage to measure ROI differences.

AI Mode Ads and Compliance Challenges

Healthcare and Regulated Industries

An emerging concern is that Google's AI Mode and AI Overviews ads, currently being tested in healthcare verticals, cannot carry AHPRA-style disclaimers. For compliance-sensitive industries like healthcare and legal, this creates a significant barrier.

Advertisers in these sectors may need to wait until Google builds disclaimer support into AI Mode ad placements. Until then, relying on traditional search and display ads with full compliance controls is the safer approach.

Experimentation Tools and AI Prompts

New Testing Capabilities

Google has launched new experimentation tools specifically for Search and AI Max campaigns. As reported by Search Engine Journal, these tools allow advertisers to run controlled experiments comparing AI-driven strategies against manual approaches.

Using AI Prompts Effectively

A guide on Practical Ecommerce outlines three AI prompts that Google Ads advertisers can use to improve campaign performance. These prompts focus on audience targeting, creative generation, and bidding strategy optimization.

Customer Lifecycle Optimization and New Beta Features

Lifecycle Goals

Google Ads is evolving its conversion goals to support customer lifecycle optimization. Advertisers can now set goals specific to acquisition, retention, and reactivation, allowing the AI to allocate budget accordingly.

Product Titles and Channel Prioritization

Two notable beta features are rolling out:

• AI-Created Product Titles Report: Google is testing a report that shows when AI rewrites product titles to improve ad relevance, helping advertisers understand and approve AI-generated changes.
• Channel Settings Prioritization Slider: An alpha test allows advertisers to prioritize certain channels (e.g., YouTube over Search) within automated campaigns, giving back some control.

Animated Loading Screens

Google is also testing loading sponsored results with Gemini animation, a visual cue that sponsored results are being generated by the AI model in real time. This could increase transparency for users.

The Big Picture: AI Reshaping Google Ads Video

Google Ads is moving rapidly toward an AI-first platform. The combination of generative video resizing, Gemini Omni creation, and lifecycle optimization means advertisers can expect:

1. Less manual creative work
2. Faster campaign setup and iteration
3. Better cross-placement performance
4. Reduced reliance on third-party tools

But these benefits come with trade-offs. Rising CPCs mean that budget efficiency is more important than ever. The mixed results from Performance Max campaigns suggest that AI automation doesn't guarantee success — smart strategy and careful monitoring remain essential.

Advertisers should start testing the new AI video tools in low-risk campaigns, measuring not just ROAS but also creative quality and brand safety. Regulated industries need to proceed with caution until compliance features catch up.

The shift from manual to AI-driven video ad creation is no longer theoretical. It's happening now in Google Ads, and advertisers who adapt early will likely gain a competitive edge.
