Google reveals AI Max for Search budget requirements in webinar

Digital Performance Director Domenico Marcoccia shared implementation guidelines from an Advanced AI Powered Advertising Webinar hosted by the search platform, highlighting a critical prerequisite that has received limited public attention since AI Max for Search campaigns launched on May 6, 2025. The webinar outlined four foundational categories covering measurement, budgets, campaign structure, and landing page optimization requirements before advertisers can successfully implement the automation suite.

The budget requirement represents one of the most specific technical prerequisites disclosed to date. According to the presentation materials, search campaigns should not be limited by budget before upgrading to AI Max. The webinar further specified that campaigns should maintain a minimum of $50 per day budget. Marcoccia noted that many advertisers have been conditioned to dismiss budget limitation flags as routine upsell prompts rather than genuine technical constraints affecting campaign performance.

The budget stipulation reflects AI Max's operational design. The system expands campaign reach by identifying conversion paths that function without traditional keyword targeting. When campaigns already operate at maximum budget capacity, the artificial intelligence lacks resources to test new audience segments or search patterns. This creates a fundamental mismatch between system capabilities and available resources during the learning phase that follows activation.

Measurement foundations precede automation

The first category in the implementation guide addresses measurement configuration. Advertisers must ensure all tags are correctly configured on important events before activating AI Max features. The system requires simplified key conversion actions aligned to clear business outcomes, eliminating unnecessary tracking complexity that can confuse machine learning algorithms.

The presentation specified Enhanced Conversions or Offline conversion action EC for leads as necessary measurement components. Data-Driven Attribution must be active within campaign settings. The guidelines explicitly warn advertisers to avoid campaigns with two or more weeks of conversion delay, as extended attribution windows prevent timely performance assessment during the learning period.

Bid strategy alignment affects eligibility

The second implementation category covers bid strategies and budget parameters. Advertisers must align their bid strategy to business objectives before activating automation features. The webinar presented two primary bidding approaches depending on advertiser priorities.

For volume-focused strategies, campaigns should use Max Conv or Max Conv. Value bidding configurations. Organizations prioritizing profitability should implement TCPA or ROAS strategies, though the presentation noted that advertisers using max clicks strategies cannot access ACA or FUE features while maintaining search matching capabilities. The distinction reflects different optimization priorities within the AI Max framework.

Budget constraints extend beyond simple daily spending thresholds. Campaigns already operating under budget limitations cannot provide AI Max with adequate resources to explore new targeting opportunities. The $50 daily minimum establishes a baseline for meaningful testing, though the presentation did not specify whether this threshold applies to individual campaigns or consolidated budget groups.

Campaign structure simplification required

The third category addresses campaign architecture and ad group organization. Before enabling AI Max features, advertisers should simplify campaign structure through consolidation. Ad groups must not contain duplicate keywords with different match type specifications, as this creates conflicting signals for the optimization algorithms.

The guidelines recommend consolidating ad groups with fewer than 30 conversions within 30-day periods. Small ad groups lack sufficient performance data for machine learning systems to identify meaningful patterns. Consolidation concentrates conversion signals, enabling faster learning cycles and more reliable optimization decisions.

The presentation advised advertisers to continue broad match implementation combined with incremental testing as they transition to AI Max. Broad match recommendations and experimentation should proceed even while campaigns undergo structural preparation. This maintains momentum in audience expansion efforts rather than waiting for complete AI Max deployment.

Landing page and website compliance

The fourth implementation category covers landing page experience and policy compliance. Advertisers should use the Landing Pages section within the interface to identify underperforming destinations. The system flags pages with technical issues, slow load times, or poor user experience metrics that could undermine campaign performance regardless of targeting accuracy.

Website compliance with platform policies requires verification before AI Max activation. The presentation specified reviewing copy for policy compliance, examining landing page text for call-to-action quality, and confirming that content aligns with benefit statements used in automated asset generation. Policy violations can trigger ad disapprovals that disrupt campaign delivery during critical learning phases.

Experimentation framework spans eight weeks

Beyond the four foundational categories, the webinar materials included detailed experimentation guidelines for measuring AI Max impact. The recommended testing framework spans eight weeks from initial activation through results analysis. This extended timeline reflects the learning requirements for keywordless matching and automated asset generation.

Week one initiates the testing period with campaign activation. The following one to two weeks constitute a learning period during which advertisers should avoid major campaign modifications. Performance during this phase does not represent steady-state results, as algorithms actively explore targeting possibilities and asset combinations.

Week three marks initial performance checks where advertisers should not make major changes to campaign settings. The experimentation phase continues through weeks four, five, six, and seven, with the recommendation to allow tests to run four to five weeks without modifications. This stability enables clean measurement of AI Max contribution without confounding variables from manual adjustments.

Week eight concludes the testing framework with results analysis. The eight-week duration provides sufficient data to assess performance across weekly seasonality patterns and account for the multi-week learning period that precedes optimization stability.

Context within automation expansion

The budget requirement represents a notable technical constraint within the broader automation expansion that has dominated search advertising development throughout 2025. The platform has systematically introduced features that reduce manual campaign management while increasing reliance on machine learning optimization.

Google Ads API v21 released on August 6, 2025 included the ai_max_setting.enable_ai_max field within the Campaign object, enabling programmatic activation of the feature suite. The API update coincided with expanded Performance Max transparency features addressing advertiser concerns about automated campaign visibility.

A podcast episode from the platform's recently launched series detailed the technical specifications behind AI Max search term matching, which combines broad match technology with keywordless matching capabilities similar to dynamic search ads. Karen Zang, product manager on search advertising and automation, explained that the system uses landing pages, creative assets, keywords within ad groups, and for English-language campaigns, generative artificial intelligence to create advertising content.

Google Ads Editor 2.10, released on July 8, 2025, brought AI Max functionality to the desktop application environment. The update enabled keyword matching optimization, URL expansion capabilities, and ad personalization systems through toggle controls within the offline editing interface.

The budget requirement disclosed in the webinar materials contrasts with the mixed early performance results documented by advertising professionals. Ezra Sackett, Director of Paid Search at Monks, shared data showing that 99 percent of impressions generated zero conversions across approximately 30,000 search terms utilizing AI Max features. The analysis suggested less than half of search terms showed keyword matching, with the majority functioning as keywordless advertisements.

The platform's October live stream presentation featured case studies demonstrating the potential for positive results under optimal conditions. L'Oreal Paris achieved 67 percent more click-through than other match types, reduced cost per conversion by 30 percent, and doubled conversion rates compared to campaigns without AI Max activation in their implementation. These results emerged from campaigns that presumably met the foundational requirements outlined in the webinar materials.

Industry implications for paid search management

The budget limitation requirement has significant implications for how paid search professionals approach AI Max adoption. The guideline effectively excludes campaigns operating under tight budget constraints from accessing the automation features, creating a threshold effect where smaller advertisers or conservative budget allocations cannot utilize the technology.

For agencies managing multiple client accounts, the requirement introduces additional complexity in determining AI Max eligibility. Budget allocation decisions now carry technical implications beyond simple spending levels, as insufficient budgets prevent access to specific automation capabilities. This may influence how agencies structure campaign budgets and present recommendations to clients regarding automation adoption.

The minimum $50 daily budget threshold places AI Max deployment within reach of mid-market advertisers while potentially excluding smaller businesses operating on limited marketing budgets. A campaign spending $50 daily allocates $1,500 monthly to search advertising, representing a moderate investment level that many small businesses cannot sustain across multiple campaigns.

The requirement that campaigns should not already be limited by budget before upgrade suggests advertisers need headroom above their current spending to accommodate the reach expansion that AI Max enables. This creates a planning consideration where advertisers must either increase budgets before activation or ensure existing budgets significantly exceed current spending levels to provide expansion capacity.

The webinar disclosure represents one of the more detailed technical requirement specifications the platform has released for AI Max implementation. Previous announcements focused primarily on performance metrics and feature descriptions rather than specific eligibility criteria or prerequisite configurations. The four-category framework provides actionable guidance for advertisers preparing campaigns for automation adoption.

The eight-week experimentation timeline also provides clarity on realistic testing periods. Earlier AI Max announcements did not specify recommended testing durations, leaving advertisers uncertain about when to evaluate results or make optimization decisions. The structured timeline with designated learning periods and performance check points offers a framework for disciplined testing approaches.
