Google's AI Max Migration Automates Search, Strategy Matters Again
Google's September 1 migration of Search campaigns to AI Max has automated broad match and creative assets, removing manual controls from marketers. The move, which affects all advertisers with no opt-out, aligns with similar automation pushes by Microsoft and Meta. Mark Ritson argues that while automation may reduce performance for some, it ultimately frees marketers to focus on higher-level strategy, product, pricing, and management. The article highlights job losses in digital marketing roles and emphasizes the enduring importance of brand strategy, pricing expertise, and non-digital channels.
Google's forced migration to AI Max marks a significant shift in search advertising automation, affecting all advertisers and signaling the industry's move toward fully automated platforms.

Google Migrates Dynamic Search Ads to AI Max
Google has moved AI Max out of beta and begun migrating Dynamic Search Ads (DSA), automatically created assets (ACA) and campaign-level broad match settings into AI Max. Voluntary upgrades start the week of publication and Google plans an automatic upgrade in September that will prevent creation of new DSA campaigns via Google Ads. Google says AI Max delivers more granular reporting (query, cross-headline, cross-landing page) and advanced controls (geo, brand controls, text guidelines) and cites an internal average lift of ~7% in conversions or conversion value versus search-term matching. Marketers interviewed say AI Max provides more visibility than past automated products like Performance Max, but raise concerns about hallucinations, spend on irrelevant queries, attribution overlap and cannibalization of other campaign types. Google will accept feedback during voluntary rollout ahead of the September change.
Google AI Max Raises Search Budgets, CPCs After One Year
One year after Google introduced AI Max for Search, advertisers and agencies report higher search spending and rising cost-per-clicks as the product shifts search toward automated, intent-driven auctions. AI Max generates target queries from landing pages, creatives and keywords, and Google says it yields roughly a 7% average conversion lift. Agencies told Digiday some clients increased search budgets 7–15% year‑on‑year tied to AI Max adoption, while reported CPC inflation ranged from around 10% to as high as 25% for some advertisers. Industry measurement firm Adthena estimated a ~35% year‑on‑year increase in advertisers participating in search auctions. Marketers are also using AI Max to reach users in Google’s AI Mode and Overviews as a response to falling organic web traffic and zero‑click behaviors.
Google Expands AI Max with Natural‑Language Ad Controls
Google has significantly expanded its AI-driven advertising suite AI Max about a year after launch, adding natural‑language campaign configuration (AI Brief), automated landing‑page selection (Final URL Expansion/FUE), and sector‑specific features for shopping and travel. AI Brief lets advertisers describe campaign goals and constraints in plain language; the system generates ad text, search queries and suggestions for iterative review. AI Max for Shopping uses Merchant Center product data to target discovery‑phase queries and can choose ad formats and landing pages automatically. Google positions these changes as efficiency gains, but the rollout raises industry questions about advertiser control, transparency, platform dependence and the traceability of automated creative and optimization decisions.
