Google Marketing Live 2026 happened yesterday, and it was — genuinely — one of the most significant events for online advertising in years. Not in a "here are some minor tweaks" way. In a "the whole architecture of how Google advertising works is changing" way.
If you sell products online and use Google Ads, this matters to you. Let me break it down.
The Big Picture: Gemini Is Now Running Your Ads
The central theme of GML 2026 wasn't a feature. It was a shift. Google's Gemini AI is now the engine underneath everything — Search, Shopping, YouTube, measurement, creative generation. The whole stack.
What that means practically: control is moving upstream. For years, running Google Ads meant managing keywords, bids, ad copy, match types — hundreds of individual decisions. That's changing. Google increasingly wants you to set your goals and brand guidelines, hand over your product data, and let Gemini handle the matching, the creative, the optimisation, and the reporting.
Some people will find that uncomfortable. But here's the honest truth: the businesses that adapt to this model will be able to compete with companies ten times their size. The ones that resist it will find themselves being left behind in parts of Google Search they can no longer reach.
AI Max for Search Is Out of Beta — And Now It's Non-Negotiable
AI Max for Search launched at GML last year as something you could experiment with. It's now out of beta and available globally — and it's no longer optional if you want full coverage on Google Search.
Here's why this matters: Google has introduced entirely new ad formats for the AI Search era. Conversational ads that respond to longer, more natural queries. Ads that appear in AI Mode (the new AI-powered search experience). Ads inside AI Overviews. If your campaigns don't have AI Max enabled, you simply won't appear in these placements. You're invisible in the fastest-growing part of Google Search.
The new features added to AI Max are genuinely useful for e-commerce businesses:
AI Brief — You can now tell AI Max about your business in plain language. Your products, your customers, what makes you different. Gemini uses that brief to steer the matching and the copy. Instead of building elaborate keyword lists, you're writing a creative brief.
AI Max for Shopping — This is new. AI Max is extending into Shopping campaigns, letting retailers reach shoppers before they've decided exactly what they want. Someone searching "something to make my home smell like a spa" can now see your diffuser ad, even if they didn't know what product they were looking for. That's capturing demand at the discovery stage, not just when someone is ready to buy.
Text Disclaimers — Required legal or compliance text is now guaranteed to appear even when AI Max is rewriting your ads. For anyone in regulated categories, this removes a key objection to enabling it.
The practical implication: if you're not running AI Max, now is the time to start.
Dynamic Search Ads Are Being Retired — September 2026 Is the Deadline
If you're running Dynamic Search Ads, they will be automatically upgraded to AI Max in September 2026. That's a hard deadline, and it's not far away.
I'd strongly recommend not waiting for the automatic upgrade. Migrating on your own terms — with proper AI Briefs, term exclusions, and brand guidelines set up — will produce far better results than a forced migration with no preparation. If this applies to you, it needs to go on the to-do list now.
Agentic Commerce: Google Is Building the Infrastructure for AI to Shop on Your Behalf
This is the bigger, longer-term story from GML 2026. Google announced what they're calling Agentic Commerce — the infrastructure for AI agents to browse, compare, and buy products on behalf of consumers.
The centrepiece is a Universal Cart: a persistent, intelligent shopping cart that lives across Google Search, YouTube, Gmail, and Gemini. You can add a product from a YouTube video, refine your search in Gemini, check prices in Search, and complete checkout — all in one connected experience, without visiting individual retailer websites.
Google also announced the Universal Commerce Protocol (UCP) — essentially a standard that lets AI agents transact on behalf of users across any merchant that supports it.
What does this mean for your business? In the short term, not much changes. But in the medium term, AI agents are going to become a real part of the purchase journey for a lot of your customers. The businesses that will benefit are those with:
- Accurate, comprehensive product data in their Google Merchant Centre feeds
- Google Pay checkout set up and working correctly
- High-quality product pages with clear specifications and descriptions
Your product feed is becoming your most important marketing asset. That's been true for a while with Performance Max, but agentic commerce takes it to another level.
YouTube: The Numbers That Should Change How You Think About It
YouTube got a significant chunk of the keynote, and the statistics Google shared are worth paying attention to.
YouTube has been the number one streaming platform by watch time for three consecutive years — ahead of Netflix, Amazon Prime Video, and all of Disney combined. That's not a small thing.
But the numbers that really stood out from an advertising perspective:
- When a YouTube creator talks about your product, viewers are 13 times more likely to search for your brand and 5 times more likely to buy
- YouTube delivers more than double the long-term ROAS of linear TV, paid social, and streaming platforms
- Google and YouTube are present in 82% of all journeys where products or brands are first discovered
- In 89% of purchase journeys, people use Google and YouTube before the largest social media platform — or skip social entirely
That last stat is striking. Nearly nine out of ten purchase journeys go through Google or YouTube. If you've been thinking of YouTube as a nice-to-have, these numbers suggest it's worth a harder look.
The new YouTube features to know about:
Ask YouTube — YouTube is getting conversational search. Users type a natural-language query ("what's the best running shoe for flat feet?"), click Ask YouTube, and get relevant videos with the ability to ask follow-up questions. This is the same shift happening in Google Search — longer, more conversational queries, richer intent signals.
YouTube Creator Partnerships Tool — A new tool for finding and working with creators whose audiences overlap with your customers. Creator content on YouTube already converts at significantly higher rates than traditional ads.
Search Behaviour Is Changing — And That's Good for Advertisers
One of the most interesting statistics from the keynote: AI Mode searches are on average three times longer than traditional searches.
Think about what that means. Longer searches mean people are sharing more context, more intent, more detail about what they want. "Running shoes" becomes "lightweight trail running shoes for someone with wide feet who runs on technical terrain." That's a fundamentally richer signal for matching your products to the right customer.
Searches with terms like "ideas for," "where should I," and "which should I buy" are growing. Discovery queries — the top of the funnel — are moving into Google Search in a big way.
This is why AI Max and Performance Max exist. The human approach of managing thousands of keyword variants can't keep up with the breadth of conversational queries people are now making. The AI can. The job changes from managing every individual keyword to making sure the AI understands your products, your customers, and your goals well enough to match them correctly.
New Measurement: Understanding What Your Ads Are Actually Worth
Google announced two new measurement metrics that address a genuine problem: the gap between when someone sees an ad and when they eventually buy.
Attributed Branded Searches (ABS) — Measures how many people searched for your brand after seeing your ad. The direct link between ad exposure and brand interest, without needing a conversion to happen straight away.
Qualified Future Conversions — Google's AI analyses early behavioural signals after an ad is seen, then predicts sales that may happen up to six months in the future. For businesses with longer consideration cycles — higher-priced products, seasonal purchases, anything people think about for a while before buying — this is a genuinely useful way to understand whether campaigns are working before the conversion data shows up.
Google also announced that Meridian — their Marketing Mix Modelling tool — is now available directly inside Google Analytics 360, with cross-channel analysis including TikTok, Snap, and Pinterest. Budget scenario planning via natural language ("how should I allocate my budget next quarter?") is built in.
What You Actually Need to Do
This is a lot of information, so let me make it practical.
Immediate priorities:
- If you're running Dynamic Search Ads, start planning the migration to AI Max now. Don't wait for September.
- If AI Max isn't enabled on your Search campaigns, turn it on. Write an AI Brief that accurately describes your business.
- Audit your product feed. Completeness and accuracy matter more than ever with AI-driven Shopping and agentic commerce coming.
Worth watching:
- AI Max for Shopping — rolling out now. Worth testing once it's available for your campaigns.
- The Universal Cart and agentic commerce features — these are summer 2026 onwards. Keep an eye on the Google Merchant Centre requirements.
- The new AI Mode ad formats — if you're on AI Max or PMax, you'll get these automatically.
The bigger picture:
The businesses that will do well in this environment are the ones that give Google's AI the best possible inputs: clear goals, detailed product data, brand guidelines that reflect what makes them different, and the right exclusions to keep things on track. The ones that will struggle are those treating Google Ads as a set-and-forget system, or those trying to fight the automation rather than directing it.
It's not about giving up control. It's about understanding where the real leverage is now — which is upstream, in the quality of the inputs you provide rather than the tactical management of individual keywords and bids.
GML 2026 was a clear statement of direction. Gemini is the operating system. AI Max and Performance Max are the primary delivery mechanisms. Agentic commerce is the near future. And the advertisers who understand that and adapt their approach accordingly are the ones who'll get the best out of what Google is building.
