In May 2025, Google launched AI Max for Search campaigns — a suite of AI-powered enhancements that can be switched on inside any existing Search campaign. By early 2026, it's become one of the most talked-about changes in Google Ads. Some advertisers love it. Others have had mixed experiences. Most are still figuring out when it makes sense.
This article explains exactly what AI Max is, what it does to your campaigns, and how to decide whether it's right for your account. There's no hype here — just a plain-language breakdown based on real-world testing and Google's own documentation.
First, the most important thing to understand: AI Max is not a new campaign type. It's a toggle you switch on inside an existing Search campaign. Think of it as an upgrade option that bundles several existing Google technologies together into one setting.
Before AI Max, these features existed in separate places: broad match keywords, Dynamic Search Ads (DSA), and Automatically Created Assets. AI Max packages them together, makes them work in concert, and gives you one place to control them. It's similar to what Google did with Performance Max — taking individual tools and combining them into a unified product.
Key point: AI Max doesn't replace your existing keywords. It adds a layer on top of them. Your search campaign structure — your keywords, ad groups, match types — stays intact. AI Max expands what those keywords can match to.
Expands your keyword coverage using broad match logic and keywordless (DSA-style) technology. Finds searches your keywords wouldn't normally trigger.
Google reviews your landing pages and existing ads to write new headlines and descriptions. The AI-generated copy adapts to the query and context.
Google can send traffic to different pages on your website — not just the URL in your ad. Similar to how this works in Performance Max campaigns.
This is the most significant feature. When you turn on AI Max, your Search campaign gets access to what Google calls "keyword list technology" — a combination of broad match expansion and the kind of keywordless matching that has powered Dynamic Search Ads for years.
In practice, this means your campaign can show ads on searches that wouldn't trigger your existing keywords. If you sell standing desks and have the keyword "standing desk," AI Max might also show your ad for "height adjustable office desk" or "ergonomic desk for home office" — searches that are clearly relevant but that you haven't explicitly targeted.
This sounds great on paper. The catch is that Google's interpretation of "relevant" doesn't always match yours. Early testing by practitioners showed a mix of genuinely useful new traffic and some garbage queries that made no sense for the business. Monitoring your search terms report closely when you first turn this on is essential.
This is Google's evolution of Automatically Created Assets — a feature that was already available (and already switched on by default in many accounts without advertisers realising it). AI Max formalises this and gives it more prominence.
Google scans your landing pages and existing ad copy, then generates new headline and description options that it thinks will perform better for specific queries. These assets are served alongside or instead of your manually written ads, depending on what Google predicts will get a better response.
You retain some control: you can pin certain headlines to ensure they always appear. But the key risk is that Google may create messaging that doesn't align with your brand voice, compliance requirements, or competitive positioning. Always review what's being generated in your Asset Report.
When enabled, Google can decide that a different page on your website is more relevant for a given search than the URL you've specified in your ad. The mechanic is identical to how Final URL Expansion works in Performance Max campaigns.
This can work well — if someone searches "standing desk with cable management" and you have a specific product page for that, Google might correctly route the traffic there instead of your generic standing desks category page. In theory, better page = better conversion rate.
In practice, Google doesn't always pick the right page. You can and should use URL exclusion rules to prevent traffic being sent to pages that aren't appropriate for paid ads — like your blog, careers page, contact page, or checkout page.
Two additional features come with AI Max that weren't previously available in standard Search campaigns:
Normally, location targeting in Google Ads works at the campaign level — you set a geographic area and that's it. AI Max adds ad-group-level location of interest targeting, which is different from where someone physically is.
The classic example: you run a hotel in Melbourne. Your campaign targets Australia. With location of interest, you can show ads to someone in Sydney who's searching "hotels in Melbourne" — without needing a separate campaign. The targeting identifies people who have intent to visit a location, regardless of where they currently are. This is genuinely new and quite useful for travel, hospitality, and local services.
AI Max gives you brand inclusion and exclusion settings at the ad group level. This lets you specify which brands your expanded targeting should or shouldn't serve against — helpful for campaigns that need to either own branded terms or avoid cannibalising a competitor's branded traffic into your broad targeting.
Here's a strategically important fact that's driven a lot of the interest in AI Max: only certain campaign types are eligible to show ads in Google's AI-powered search experiences — specifically AI Overviews and AI Mode.
| Campaign Type | Standard Search Results | AI Overviews | AI Mode |
|---|---|---|---|
| Search (exact/phrase match) | ✓ Yes | ✗ No | ✗ No |
| Search (broad match) | ✓ Yes | ~ Limited | ~ Limited |
| Search with AI Max | ✓ Yes | ✓ Yes | ✓ Yes |
| Performance Max | ✓ Yes | ✓ Yes | ✓ Yes |
AI Overviews are the AI-generated summaries that appear above traditional search results for an increasing range of queries. AI Mode is Google's new conversational search experience, available as a separate tab. As of early 2026, Google is actively expanding ads into both of these surfaces — and AI Max-enabled Search campaigns are eligible for these placements.
If maintaining visibility as Google's search interface evolves toward AI-first experiences is a priority for your business, that's a legitimate reason to pay attention to AI Max adoption now rather than later.
Google's official figures: advertisers who activate AI Max typically see 14% more conversions or conversion value at a similar CPA/ROAS. For campaigns that were still primarily using exact and phrase match keywords, the claimed uplift is 27%.
These numbers come from Google's own case studies and beta testing data — predominantly with large advertisers who have substantial conversion volume and data for Google's algorithms to optimise against. The results for smaller accounts with fewer monthly conversions are less predictable.
Real-world testing by independent practitioners has shown more nuanced results. Some accounts see genuine conversion volume growth. Others see volume increase but quality drop — more clicks, lower conversion rate, similar or worse revenue. The consensus emerging from the PPC community in late 2025 is roughly:
AI Max significantly increases the reach of your keywords — which means it will spend more budget. If your campaign is already constrained by budget, turning on AI Max may not find much new volume. If it isn't budget-constrained, be prepared for spend to increase as Google tests the expanded traffic.
Don't just flip the toggle and walk away. The right approach is structured testing with guardrails in place before you launch.
Choose a campaign with good conversion volume, Smart Bidding already active, and reliable tracking. Don't start with your brand campaign or a low-volume niche campaign.
Google's Campaign Experiments tool lets you split traffic 50/50 between your original setup and an AI Max variant. This gives you a controlled comparison rather than a before-and-after that could be influenced by seasonality.
In Final URL Expansion settings, add any pages you don't want traffic sent to — blog posts, your careers page, the checkout page, or any pages that aren't designed to convert paid traffic.
Decide whether you want brand inclusion (only serve on relevant branded searches) or brand exclusions (don't target competitor brand terms). Set these at the ad group level so you can be specific.
AI Max expands your reach, which means new — and potentially irrelevant — search terms. Check your Search Terms Report regularly and add negatives for anything that's clearly off-target. The AI learns over time, but it won't catch everything immediately.
Go to your Asset Report and check what Google has been generating. Disable any headlines or descriptions that are factually incorrect, off-brand, or make claims you're not comfortable with.
A question that comes up constantly. The short answer: they're different tools for different situations, and you can (and often should) run both.
| Feature | AI Max for Search | Performance Max |
|---|---|---|
| Campaign type | Setting within Search campaign | Separate campaign type |
| Ad formats | Text ads (Search only) | Text, image, video, Shopping across all networks |
| Keyword control | Your keywords remain active | No traditional keywords — asset-based targeting |
| Search term visibility | Full search term report available | Limited search term visibility |
| Best for | Expanding reach within Search, maintaining structure | Full-funnel coverage across all Google inventory |
| Minimum conversion volume | Lower threshold — works from ~20–30/month | Generally needs higher conversion volume to work well |
If you're running a Performance Max campaign and a Search campaign, AI Max sits between them — giving your Search campaign expanded reach while you retain more control than Performance Max allows. Many practitioners are testing the combination: Performance Max for full-funnel reach, AI Max on Search for expanded keyword discovery with more transparency.
AI Max for Search is a genuine evolution of Search campaign capabilities — not just a rebrand. The combination of expanded matching, AI-generated creative, and URL routing is meaningfully different from what was available before, even if each individual technology existed in some form.
The strategic reason to pay attention now, beyond the conversion volume claims, is eligibility for AI Overviews and AI Mode placements. As Google shifts more of its search interface toward AI-generated experiences, the campaigns eligible to appear in those experiences will matter. AI Max is currently the most direct path to that eligibility within Search campaigns.
That said — don't turn it on just because Google is recommending it. Test it properly, monitor closely for the first few weeks, and judge it on your account's actual results. The 14–27% conversion lifts Google quotes are averages across large datasets. Your account may perform better, worse, or differently depending on your vertical, budget, and conversion volume.
Run a 50/50 experiment on your best-performing Search campaign for 4–6 weeks. Compare conversion volume, CPA, and search term quality between the control and experiment. Let the data tell you whether AI Max is adding value — not Google's case studies.

Common questions about this topic.
AI Max for Search is a campaign setting in Google Ads that enables three AI-powered capabilities: broader search term matching beyond your keyword list, AI-generated text customisation that adapts headlines and descriptions to each query, and final URL expansion that sends users to the most relevant page on your site rather than your specified URL.
Broad match is a keyword match type that expands a single keyword to related queries. AI Max is a campaign-level setting that works on top of your existing match types — it enables keywordless matching that goes beyond any individual keyword, while also adding AI-generated creative and dynamic URL routing. You can use both together.
Yes, if you enable the final URL expansion feature within AI Max, Google may send users to a different page on your site than the one you specified — one it determines is more relevant to the query. You can disable this feature or restrict it using URL exclusions while still keeping the other AI Max features active.
AI Max includes brand controls that let you restrict AI-generated ads from appearing for your own brand terms or competitors' brand terms. You set these in the campaign settings using brand lists, so your branded campaigns remain under your control.
Not necessarily. AI Max is best suited for advertisers comfortable with less control in exchange for broader reach and AI-generated creative. It performs best when you have sufficient conversion data (30+ conversions in 30 days), strong landing page content across your site, and a willingness to trust Google's AI for creative variations. For tightly controlled brand campaigns or small budgets, a more conservative approach may be preferable.
