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.
A major Google ad product is changing search ad mechanics and automation, driving higher budgets, CPC inflation and increased auction competition—material effects for media buyers and search ad strategies.

Google Announces New AI Max Features for Search Ads
Google expanded its AI Max advertising product, extending it beyond search into shopping and travel and adding new advertiser controls. The update, announced the week of April 30, 2026 (after Alphabet reported Q1 revenue of $110 billion, up 22% year-on-year), introduces AI Brief — a natural-language control plane for describing messaging, targeting and audience constraints — plus Final URL Expansion with text-disclaimer controls and integration with Merchant Center product feeds. Google positions AI Max as a middle ground between fully automated Performance Max and manual campaign management, shifting advertiser work upstream from keyword lists and bid mechanics to higher-level objectives, data signals, creative guardrails and intent prompts. Google emphasizes these features as optional steering tools, while industry voices note ongoing concerns about control and transparency. Epiminds founder Elias Malm noted the trend toward responsive, asset-driven ad formats.
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 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.
