Google's AI Search adds links, Ads adds journey bidding, ChatGPT ads go global

Two threads dominated the week. Google shipped link-surface and bidding changes that affect how organic and paid programs report and optimize, while OpenAI quietly extended ChatGPT ads to the UK, Brazil, Japan, South Korea, and Mexico. Publishers still have no new click data for AI Search, and studies keep showing referral declines. On the ad-tech side, PubMatic disclosed 30+ fully autonomous agentic campaigns, The Trade Desk lost CSO Samantha Jacobson to OpenAI, and Google rolled out a UCP-powered checkout directly on the main SERP. Bing also published a grounding framework that reframes how AI answer visibility should be measured. Recalculate two things this week: your AI Search measurement model now that more links appear without reporting, and your Performance Max and Search bid-strategy assumptions under journey-aware bidding.

Mueller clarifies Preferred Sources does not override quality signals

Google's John Mueller addressed whether Preferred Sources acts as a trust override for ranking, confirming it does not bypass low-quality signals. Sites added to a user's Preferred Sources still need to meet standard quality thresholds to surface in AI Search and Top Stories.

Google Search
Patrick's take

Stop pitching Preferred Sources as a brand-defense play to clients. It is a personalization feature, not a ranking shortcut, and quality remediation work still has to come first.

Google expands Universal Commerce Protocol checkout to the main SERP

Google began rolling out UCP-powered checkout to product listings in the main search results, allowing purchases without leaving the SERP. The expansion moves transactions further upstream from merchant sites and shifts attribution and analytics for ecommerce SEO programs.

Google Search Google Merchant Center
Patrick's take

Audit your product feed coverage and structured data for items where the SERP transaction will replace a site visit. Last-click attribution will understate Google's contribution, so add a UCP-aware view to your weekly ecommerce report.

Google Ads launches Journey-aware Bidding and new pacing controls

Google Ads introduced Journey-aware Bidding, expanded Smart Bidding Exploration, and added new budget pacing controls across Search, Shopping, and Performance Max. Smart Bidding now factors where a user sits in the path to conversion, and pacing controls give advertisers more granular spend distribution within a flight.

Google Ads Performance Max
Patrick's take

Re-baseline your tCPA and tROAS targets before turning Journey-aware Bidding on. Historical conversion paths will be reweighted, and accounts with thin conversion volume will see the most variance in the first two to four weeks.

PubMatic discloses 30+ fully autonomous agentic campaigns on AgenticOS

On its Q1 earnings call, PubMatic CEO Rajeev Goel said the company has run more than 30 end-to-end autonomous agentic campaigns through AgenticOS, beyond its 1,000+ direct-deal integrations. The disclosure marks one of the first concrete volume figures for agentic ad buying outside of test environments.

PubMatic
Patrick's take

Ask your SSP and DSP partners for their actual agentic campaign counts and outcomes, not their roadmap decks. The gap between PubMatic's 30 live campaigns and most vendor pitches is where the next 18 months of programmatic budget will be decided.

Google AI Max for Search opens to more advertisers with new steering controls

Google marked one year of AI Max for Search by adding controls to steer query expansion and asset generation, plus expanding eligibility to more advertisers. New Shopping and Travel-specific variants of AI Max also launched, replacing portions of legacy Shopping and travel campaign workflows.

Google Ads AI Max
Patrick's take

If you have been holding off on AI Max because of brand safety on query expansion, the new steering controls are worth a structured pilot. Run it on one ad group with negative keyword and brand-list guardrails before expanding.

Closing the attribution gap in agentic search

Semrush published a measurement walkthrough on the attribution gap created by agentic search tools, where AI agents shape buying decisions before any tracked click. The piece outlines server-log analysis, prompt monitoring, and assisted-conversion modeling as compensating measurements when GA4 and DSP attribution miss the upstream activity.

GA4 ChatGPT Perplexity
Patrick's take

Add an AI-influence row to your monthly client reporting now, even if the methodology is rough. The teams that wait for clean attribution will lose budget arguments to teams who can show directional data this quarter.

The Trade Desk CSO Samantha Jacobson departs for OpenAI

The Trade Desk reported $689M in Q1 2026 revenue, up 12% year over year, but disclosed that Chief Strategy Officer Samantha Jacobson is leaving for OpenAI. The move adds to a string of senior ad-tech hires at OpenAI as it builds out its commercial organization ahead of broader ChatGPT ad rollout.

The Trade Desk OpenAI
Patrick's take

OpenAI is staffing for a real ad business, not an experiment. Brief your CMO that ChatGPT inventory will likely have credible measurement and identity stories within 12 months, and plan test budgets accordingly.

Google donates Agent Payments Protocol to the FIDO Alliance

Google contributed the Agent Payments Protocol (AP2) to the FIDO Alliance to support standards for AI-agent-driven commerce transactions. The donation positions AP2 as a candidate cross-vendor standard for authenticating and authorizing payments initiated by autonomous agents.

Google FIDO Alliance
Patrick's take

Regulated and government clients should track AP2 governance now, not after it lands in browsers. Procurement, accessibility, and identity teams will all have a stake once agent-initiated transactions hit production sites.
