Scaling AI Max campaigns into new geographic markets is more complex than duplicating a campaign and changing the location target. Language, currency, regulatory requirements, and performance signals all differ by market. Here's how to approach international AI Max expansion systematically.
Why AI Max International Campaigns Need Separate Campaigns per Market
Don't: Run a single AI Max campaign targeting 10 countries.
Do: Create separate AI Max campaigns per language/country combination.
Reasons:
AI model calibration: AI Max's bidding model calibrates per campaign. Different countries have different CPCs, conversion rates, and user behavior. A single campaign mixing US (high CPC, high conversion value) with Eastern European markets (lower CPC) will optimize poorly for both.
Asset relevance: AI Max creates and serves assets in the language of the user's browser/search settings. If you have English assets in a campaign targeting France, the AI will serve English ads to French users — technically possible but suboptimal.
Budget control: Country-level budget control is only possible with country-level campaigns. If you need to allocate 70% of budget to the US and 30% to the UK, you need separate campaigns.
Reporting clarity: Aggregate campaign reports mix market performance. Separate campaigns give clean per-market ROAS and CPA data.
Creating Multi-Language Asset Groups
Within a country campaign, if your market has multiple significant languages (Canada: English + French; Belgium: Dutch + French + German; Switzerland: German + French + Italian), you have two options:
Option A: Separate campaigns per language (cleaner, more control)
Option B: Multiple asset groups per language within one campaign:
- Asset Group 1: English assets, URL: /en/ landing page
- Asset Group 2: French assets, URL: /fr/ landing page
Option B works, but requires careful URL setup — ensure the English asset group's URL expansion is limited to /en/ pages and French to /fr/ pages, otherwise the AI may cross-reference language content.
AI Max for Shopping and Currency/Merchant Center Accounts
For AI Max for Shopping (https://yositeup.com/blog/google-ai-max-shopping-replacing-performance-max-2026) in international markets, each country may need a separate Merchant Center account and feed due to:
- Currency requirements (Merchant Center feeds are currency-specific)
- Product availability differences by country
- Price differences by market
- Local regulations affecting product listings
You can use a Merchant Center Multi-Client Account (MCA) to manage multiple country feeds under one login.
DSA to AI Max Migration for International Markets
When migrating DSA to AI Max for Search (https://yositeup.com/blog/google-ads-dsa-ai-max-migration-february-2027) in international markets: check whether your DSA campaigns were targeting country-specific URL structures (e.g., /uk/ or /de/ subfolders). AI Max's URL expansion should be similarly constrained to the country-specific URL structure, not the entire domain.
Set explicit URL expansion settings to include only the language/country-specific subfolder for each campaign. Otherwise AI Max may serve German users ads leading to English-language product pages.
July 2026 ToS and International Compliance
The July 2026 ToS (https://yositeup.com/blog/google-ads-tos-july-2026-ai-automation-what-changed) has country-specific compliance requirements that apply to AI Max:
- EU countries: Consent Mode v2 required for AI Max audience signals and tracking
- UK: Post-Brexit, UK-specific policy requirements apply (separate from EU GDPR in some areas)
- Brazil: LGPD consent requirements apply to Brazilian audiences
- Canada: CASL compliance for any email-based Customer Match data
AI Max's "Automatically created assets" must comply with local advertising laws in each target market. Languages the AI generates content in (if you enable auto-generated assets) must meet accuracy requirements in those languages.
The June 2026 Deletion and International Market Data
The June 2026 data deletion (https://yositeup.com/blog/google-ads-reporting-data-deleted-june-2026) affected all markets equally. For international AI Max campaigns:
- European markets running AI Max during the deleted period lost that period's data just like US campaigns
- Markets where Q2 is a peak period (e.g., UK summer retail, European pre-vacation shopping) were particularly affected
- Country-level ROAS comparisons for the deleted period should not be made — the benchmark is missing
Performance Signals Transfer Between Markets
AI Max doesn't transfer performance signals between country campaigns — each campaign builds its own model independently. This means:
- A new AI Max campaign in Germany starts from scratch, even if you have a highly optimized US campaign
- The German campaign's learning phase takes the same 2-4 weeks as any new AI Max campaign
- You can't bootstrap the German campaign with US audience signals (different users, different behavior)
The only cross-market signal transfer is through Customer Match: if you have German-speaking customers in your CRM, upload them as audience signals for the German campaign. This gives the German AI Max campaign a head start in understanding your customer profile.
Scaling: Market Prioritization for AI Max Rollout
If you're rolling out AI Max to 5 new markets simultaneously, don't launch all 5 at once. Each market needs your attention during the learning phase. Prioritize:
- Largest revenue opportunity (highest search volume, best existing organic performance)
- Markets where you have the most Customer Match data (better initial signals)
- Markets most similar to your existing AI Max market (similar behavior = faster calibration)
Launch 1-2 markets, let them stabilize for 4-6 weeks, then add the next 1-2 markets.
