Editor's note: Updated September 2026 with the latest on AI Max availability and Google's Power Pack.
In the enterprise search accounts our team manages, the question has shifted over the past year. Marketers aren't asking whether to use AI in search, they're asking where the automation should stop and where their own strategy should take over. That's usually the moment Search Ads 360 (SA360) comes up. While both Google Ads and Search Ads 360 (SA360) leverage AI, understanding their distinct approaches and capabilities is crucial for determining the best fit for your business, especially as you look to scale.
How AI is changing enterprise search advertising
It’s become clear that AI is no longer just a tool for optimization; it's becoming a central co-strategist for marketers. Google is expanding ad placements into AI Overviews and the conversational “AI Mode,” placing brands directly within generative summaries and interactive search experiences. Google's Power Pack — an enhanced Performance Max, AI Max for Search campaigns, and improved Demand Gen — has moved from announcement to general availability, and AI Max is now auto-upgrading eligible Search campaigns.
Alongside creative and automation, measurement is also evolving. Google continues to expand AI-powered attribution and cross-channel insights, giving marketers clearer visibility into what’s driving outcomes.
This shift underscores why enterprise tools like Search Ads 360 remain critical in an AI-first world and raises an important question for your team: which tools can offer the scale, control, and insights needed to thrive?
What Google Ads Performance Max does well for growing advertisers
Google Ads Performance Max campaigns offer a highly accessible entry point into AI-powered advertising, particularly for small to mid-sized businesses or those with more streamlined campaign structures. Performance Max leverages AI extensively for setup and management, requiring advertisers to provide general inputs while the AI autonomously handles targeting, bidding, placements, and creative optimization across Google’s ecosystem.
The appeal of Performance Max lies in its ease of use, speed to launch, and automated optimization. For many advertisers, it’s a powerful solution for managing campaigns efficiently within Google’s network.
However, for organizations with more complex marketing needs — especially those managing cross-channel strategies, high-volume budgets or nuanced business objectives — there may come a point where greater visibility, flexibility, and platform interoperability become essential. Even with updates like channel performance reports and expanded search term insights, you might want:
- More granular control over placements and budget allocation
- Advanced A/B testing capabilities for scaled optimization
- Multi-channel attribution beyond Google-owned properties
- Tools to mitigate cannibalization across overlapping campaigns
This is where Search Ads 360 enters the conversation. Not as a replacement for Google Ads, but as a platform that gives you more customization and strategic oversight, so you can scale your efforts.

Search Ads 360’s AI capabilities are designed specifically for enterprise needs, offering flexibility and intelligence that support more sophisticated marketing strategies.
How SA360 portfolio bidding works across multiple search engines
While Google Ads offers powerful Smart Bidding features, Search Ads 360 takes it further with custom portfolio bidding strategies tailored to your business goals across multiple campaigns and platforms. Its machine learning engine optimizes bids in real time, not just to improve individual campaigns, but to maximize conversions or revenue across your entire search portfolio.
With Search Ads 360, you can:

Responsive search ads (RSA) reporting in SA360
Both Google Ads and Search Ads 360 support RSA automation, but Search Ads 360 offers richer reporting and performance insights. It can show you more granularly which assets are resonating, which combinations perform best, and how you can improve ads based on a wider set of signals, like performance across multiple search engines, landing page relevance, and historical performance data.
This deeper layer of intelligence can help you fine-tune creative strategies and drive stronger conversion results.
How Floodlight attribution works in SA360
Floodlight is the conversion tracking backbone of Google Marketing Platform, and, when paired with Search Ads 360, it provides a consistent way to measure and attribute conversions across search engines, campaigns, and even channels beyond Google when tagged correctly.
This gives you both tactical visibility and enterprise-level intelligence. With Floodlight, you can:
- Apply advanced attribution models (last click, first click, linear, time decay, position-based, and data-driven) across all tagged touchpoints
- Gain clearer insights into how different engines, campaigns, and keywords contribute to conversions
- Tailor Floodlight tags to capture both strategic and tactical actions, from high-value transactions to nuanced micro-conversions
- Feed attribution insights directly into Search Ads 360’s bidding and budgeting models to improve decision-making at scale
In my opinion, the real power comes when Search Ads 360’s AI and portfolio bidding layer on top. Rather than raw data, Floodlight becomes actionable intelligence: helping you decide where to scale, where to cut, and how to maximize ROI across a complex, multi-engine portfolio.
Cross-channel campaign management across Google Marketing Platform
While Search Ads 360 offers powerful AI-driven features, its Google Marketing Platform integration is just as important. Rather than using Search Ads 360in isolation, you can leverage it with:
- Campaign Manager 360 for ad serving and rich media
- Display & Video 360 for programmatic buying
- Google Analytics 4 for advanced web and app analytics
Three benefits of connecting SA360 to the rest of Google Marketing Platform
-
Holistic campaign management: Manage and optimize search campaigns alongside display, video and even social media efforts, all through centralized workflows.
-
Unified reporting: Consolidate reporting across your digital channels to make better-informed decisions, faster.
-
Advanced audience management: Share and activate custom audience segments created in other GMP products directly within Search Ads 360, enabling more precise targeting and personalization.
Building a search strategy that scales across engines
AI is redefining the very foundation of search advertising. Google’s “Power Pack” makes AI accessible and efficient, while Search Ads 360 ensures you can scale those efficiencies across channels, engines, and complex portfolios.
Together, they provide a continuum: from powerful simplicity in Google Ads Performance Max to enterprise-grade control, attribution, and integration in Search Ads 360. For marketers, the opportunity lies in knowing when to layer them to accelerate growth. The teams I see getting the most out of Search Ads 360 are the ones who know exactly which decisions they still want to own. They let the machine learning handle everything else, and they're specific about where that line sits.
