Google Ask Advisor: One Gemini Agent Across Ads, Analytics, and Merchant Center
Google collapsed its scattered in-product AI assistants into a single cross-platform agent, and that changes how campaign decisions get made, not just how fast they get made.
Google AdsKey takeaways
- Ask Advisor is a single Gemini-powered agent that spans Google Ads, Analytics, Merchant Center, and DV360, replacing separate in-product assistants that couldn't share context with each other.
- The practical shift is workflow, not just speed: a marketer can prompt one conversation to pull product data from Merchant Center, build an audience from Analytics, and launch a campaign in Ads without switching tabs or re-explaining context.
- Ask Advisor is the direct successor to Ads Advisor, which reached all English-language Google Ads accounts in December 2025, so most buyers already have a version of this in their account and need to understand what changed.
- The bigger risk isn't trusting the agent too little, it's trusting it too much on cross-platform recommendations where the agent optimizes for what it can measure inside Google's stack, not your actual business goal.
- Merchant Center integration is still 'coming soon,' so any workflow that involves product-level campaign creation through Ask Advisor is not live yet and shouldn't be built into operating procedures.
What changed
Google announced Ask Advisor at Google Marketing Live 2026 (May 20, 2026): a unified Gemini-powered agent that works across Google Ads, Google Analytics, Merchant Center, and Google Marketing Platform including DV360. It replaces what were previously siloed in-product assistants with a single conversational agent that retains context as it moves between products. The agent launched in beta for English-language accounts globally, with Merchant Center integration listed as coming soon. It is the direct evolution of Ads Advisor, the campaign diagnostics tool that rolled out to all English-language Google Ads accounts in December 2025.
What to test
["Use Ask Advisor to diagnose a recent underperforming campaign by asking it to cross-reference Google Ads cost and conversion data with Analytics audience behavior, measure whether the recommended fix matches your own diagnosis and track whether acting on it moves CPA within two weeks.", "Ask Ask Advisor to suggest a new audience segment based on Analytics data for an existing campaign, then run that segment as an observation layer against your current targeting for 30 days, the bar is whether it generates a CTR lift of at least 10% or a lower CPA than the control segment before you promote it to targeting.", "Compare the time-to-setup for a new campaign built through Ask Advisor's conversational workflow versus your standard manual process, if setup time drops by more than 30 minutes without a meaningful change in launch-week ROAS, the workflow earns a permanent spot in the playbook.", "Log every Ask Advisor recommendation your team overrides for one month and record the outcome, this creates a calibration baseline for how much the agent's cross-platform suggestions align with your actual account history before you increase how much autonomy you give it."]
Who it affects: Performance marketers running Google Ads alongside Analytics and Merchant Center, especially e-commerce accounts, retail media buyers, and agencies managing multi-product Google stacks at mid-to-high spend levels where cross-platform decision-making is a daily task.
What changed
Google announced Ask Advisor at Google Marketing Live 2026 on May 20. It's a single Gemini-powered agent that spans Google Ads, Google Analytics, Merchant Center, and the broader Google Marketing Platform (including DV360). Previously, each product had its own assistant that couldn't share context with the others. Ask Advisor replaces that fragmented setup with one continuous conversation: you can ask it to pull product data from Merchant Center, identify an audience in Analytics, and launch a campaign in Google Ads, all in a single prompt thread without rebuilding context between steps.
It launched in beta for English-language accounts globally. Merchant Center integration is described as "coming soon", it's not live. Ask Advisor is the direct successor to Ads Advisor, the campaign-level diagnostics and optimization assistant that reached all English-language Google Ads accounts in December 2025 after a staged rollout that started in September 2025.
Who it affects
If you're running Google Ads alongside Analytics and Merchant Center, almost every e-commerce account does, this touches your day-to-day workflow directly. Agencies managing multiple clients on the Google stack, retail media buyers coordinating product feeds with campaign targeting, and any performance team that currently spends meaningful time switching between Google products to make a single decision are the most exposed to both the upside and the risk here.
Lower-spend accounts running simple single-product campaigns in Ads only will feel this less. The cross-platform value only materializes when there's actually data to pull across multiple products.
Why it matters
The previous state of in-product AI assistance was siloed by design. Ads Advisor could tell you a campaign had a high CPA, but it couldn't tell you whether the underperforming audience segment was also bouncing in Analytics, or whether the product feed in Merchant Center had a disapproval issue driving it. You had to make those connections manually. Ask Advisor, in theory, closes that gap.
The mechanism that makes this meaningful is context persistence. A conversational agent that carries context from one product into the next can surface correlations that a human moving between tabs will miss, or skip because it takes too long. That's a genuine workflow change, not just a UI refresh.
But there's a real risk on the other side. Google's agent optimizes for what Google can measure inside Google's stack. That's not the same as your actual business objective, especially for advertisers who use third-party attribution (last-click means Google logs the purchase a few days after the click, and different tools disagree on the count), blend online and offline conversion data, or have margin profiles that don't map cleanly to ROAS targets. An agent that connects four Google products is still only connecting four Google products. Its recommendations will reflect that boundary.
The other structural risk: the more seamlessly the agent can launch and modify campaigns, the easier it is to act on a recommendation without the verification step that a manual workflow naturally forces. Speed is only an advantage when the underlying recommendation is sound.
The play
-
Map your current cross-platform diagnostic workflow first. Before relying on Ask Advisor for cross-product analysis, write down how you currently connect Ads performance to Analytics behavior and Merchant Center feed health. That map becomes your verification checklist when Ask Advisor gives you a recommendation. Metric to watch: how often its root-cause diagnosis matches yours, logged over 30 days.
-
Use it in observation mode before action mode. Ask Ask Advisor to suggest audience segments based on Analytics data, but add them as observation-only layers in your ad groups (meaning Google shows you performance data without restricting delivery) before promoting them to actual targeting. The bar: a segment needs to show at least 10% lower CPA than your current targeting over 30 days before it earns a targeting role.
-
Run one campaign setup through the conversational workflow versus your manual process. Track setup time and launch-week ROAS. If Ask Advisor cuts setup time by 30 minutes or more without a ROAS penalty in the first week, the workflow earns a permanent spot. If ROAS is materially worse, the agent made a targeting or bidding call you'd have caught manually.
-
Build a recommendation log. Every time your team overrides Ask Advisor, record what it suggested, what you did instead, and what happened. After 60 days you'll have a real calibration of how much to trust its cross-platform read on your specific account. This is the step most teams skip, and it's the one that determines whether the agent saves time or costs it.
Watch-outs
Don't build Merchant Center workflows into Ask Advisor yet. That integration isn't live. Any planning that assumes product-feed-to-campaign automation is available now will hit a wall.
The "always-on strategic partner" framing from Google is worth treating skeptically. An agent that recommends increasing budget, shifting to a broader match type, or expanding audience reach is, on net, an agent that drives more spend through Google's system. That's not a reason to ignore its recommendations, but it is a reason to ask what the recommendation optimizes for before acting on it.
Also watch for agents taking action in accounts where multiple users or automation rules are already live. Overlapping interventions (a human override, an automated rule, and an agent action all touching the same campaign in the same week) produce attribution chaos that's hard to unwind.
The WhyItWon angle
Ask Advisor is, at its core, a signal aggregator: it pulls data from across Google's stack and tries to tell you what to do next. The gap it doesn't close is knowing what creative to run on the campaigns it helps you build or adjust. A cross-platform agent can identify an audience segment or flag a budget inefficiency, but it has no model of what ad concept will resonate with that segment for your brand, given your competitive set and what's already working in your account. That's the exact problem WhyItWon is built for: it reads your existing ads, your rivals' ads, and your customer signals to score what creative will win before you spend. As Ask Advisor routes more of the structural campaign decisions through a conversational interface, knowing in advance which creative concept to put into those campaigns becomes the variable that separates accounts that improve from accounts that just change faster.
