For years, the Google Search campaign was the most controllable tool in the Google Ads account: you chose the keywords, wrote the ads, and managed the bids. In 2026, Google is fundamentally shifting that logic. With AI Max for Search campaigns, the same AI automation that made Performance Max big is now moving into classic search – since rolling out of beta, AI Max has been generally available and is gradually becoming the standard.
The good news for advertisers: unlike Performance Max, AI Max remains a pure Search campaign. You keep more control than with the PMax black box – if you know the right control levers. We show what AI Max really delivers, where its limits are, and how SMBs in particular can use this shift to their advantage rather than simply letting it happen to them.
1. What AI Max Is – and Why Google Is Rebuilding Search
AI Max isn't a new campaign type – it's an AI feature suite that you activate within existing Search campaigns. Google describes it as a "one-click" path to more reach: the AI expands your keyword base with matching search queries, generates additional ad copy, and sends users to the most relevant landing page in each case. The strategic backdrop: more and more search queries are long, conversational, and unique – classic keyword lists fall short there.
Google puts the effect at an average of around 7% more conversions or conversion value at a similar CPA/ROAS, provided the full feature set is used. That figure, however, comes from the global average of large ad accounts – it's not a guaranteed result, but a benchmark you still need to prove out in your own account.
In short: AI Max brings PMax-style AI into the Search campaign – but with significantly more control options. It's the middle ground between keyword-based control and fully automated reach.
2. The Two Building Blocks: Search-Term Matching & AI Assets
AI Max consists of two clearly distinct building blocks, which you can activate individually or together:
1. Search-Term Matching. Using broad-match and keywordless technology, AI Max finds relevant, well-performing search queries that your keyword list doesn't cover. The AI learns from your existing keywords, ads, and target URLs – so your existing campaign is the training foundation, not a blank slate.
2. Asset optimization. This building block bundles two functions: text customization (formerly "automatically created assets") generates new headlines and descriptions from your landing page, ads, and keywords. Final URL expansion automatically directs users to the most fitting page on your website – instead of rigidly to one fixed target URL.
Schematic comparison of the functional logic. As of July 2026.
3. Ads in AI Mode: Advertising Moves Into the AI Answer
At Google Marketing Live 2026, Google announced that ads will in future also run directly in AI Mode – the conversational AI search experience in which Google delivers whole answers instead of a list of links. These ads are delivered through two already-familiar formats: AI Max and Performance Max. Anyone using AI Max is therefore automatically qualified for this new ad surface.
Important context: the test is initially running only for US advertisers and English-language queries. For the German market, this is a preview, not an immediate lever. But the direction is clear – advertising is shifting to where users will be searching in the future: right inside the AI answer. Anyone who understands the mechanics early will be prepared once it arrives in Germany.
4. Staying in Control: Brand, Location & URL Settings
The crucial difference from Performance Max: AI Max gives you back precise control instruments that simply don't exist under pure automation. Use them actively – otherwise you're leaving more to the AI than necessary.
Brand Controls. At the campaign and ad group level, you define which brands your ads should appear for – and explicitly which brands they should not appear alongside. This is especially important for specialist retailers and service providers, to avoid wasted spend and mismatched associations.
Locations of interest. You control location relevance more finely than through the classic geographic targeting area – relevant for locally operating businesses that only want to be visible in specific regions.
URL rules. When final URL expansion is active, you should define which pages (such as terms and conditions, careers, or outdated promotions) remain excluded, so the AI doesn't send users to unsuitable destinations.
Practical tip: Don't treat AI Max as a "one-click autopilot." The biggest mistake is activating every AI feature and leaving the controls empty. The right approach is exactly the opposite: turn the AI on, and set clear guardrails.
5. Automatic Migration: DSA, ACA & Broad Match
AI Max partly arrives on its own: campaigns with Dynamic Search Ads (DSA), automatically created assets (ACA), and campaign-wide broad-match settings are set to be automatically switched to AI Max. After significant criticism from advertisers, however, Google has postponed this auto-migration from September 2026 to February 2027.
For you, that means: you have time – but no reason to wait. Anyone who deliberately tests AI Max now in a controlled test campaign will know their own numbers by the time the forced migration hits, and can make an informed decision about which features to keep. In parallel, Google is expanding AI Max to Shopping campaigns – so the AI logic isn't becoming the exception, it's becoming the rule.
6. What AI Max Means for SMB Budgets
Honesty matters more than marketing euphoria here. Google's performance figures come predominantly from large accounts with six- to seven-figure annual budgets. An SMB with a monthly budget of 1,000 to 5,000 euros has less conversion data – and AI systems learn from data. What gets optimized within days for a large account can take weeks on a small budget.
That's not a reason to avoid AI Max – but it is a reason to roll it out with discipline: tight brand and URL controls, clear conversion goals, and regular manual review of the AI-generated copy. The mistake would be seeing AI Max as a substitute for strategy. In reality, your work simply shifts: away from keyword micromanagement, toward semantic briefing, first-party measurement, and creative governance.
7. GDPR, the AI Act & Clean Tracking
AI-powered advertising can be run in a data-protection-compliant way in Germany – provided consent, tracking, and profiling are set up cleanly. The GDPR, the German Telecommunications-Digital-Services-Data-Protection Act (TDDDG), and the Digital Services Act restrict personalized advertising, but they don't prohibit it. Before activating, check in particular whether your Enhanced Conversions setup is compatible with your data protection requirements.
In addition, a new stage of the EU AI Act takes effect on August 2, 2026, introducing transparency obligations for AI-generated content. Anyone deploying AI-generated copy at scale should get their own labeling and documentation practices in order early – not only once it's being audited.
8. Checklist: Rolling Out AI Max in a Controlled Way
Here's how to test AI Max without giving up control:
- Start with one well-performing Search campaign as your test field, not the whole account.
- Activate Search-Term Matching and check the search terms report daily at first.
- Set Brand Controls at the campaign and ad group level (include and exclude).
- With final URL expansion, explicitly exclude unsuitable pages.
- Regularly review AI-generated headlines and descriptions, and remove weak assets.
- Set up first-party tracking and Enhanced Conversions in a GDPR-compliant way.
- Measure against the baseline campaign after 2–4 weeks – only then roll out.
9. Conclusion: Fewer Keywords, More Control
AI Max is the next logical step in Google's AI strategy – and, unlike Performance Max, an offering that doesn't take control away but shifts it. The era of pure keyword micromanagement is ending; in its place comes the art of guiding an AI with clear guardrails, good data, and clean assets.
For SMBs, that's an opportunity if they approach it with discipline: test small, set controls, measure results. Anyone who blindly switches on AI Max and leaves the field entirely to automation, on the other hand, is giving away budget. The advantage in 2026 doesn't come from the feature alone – it comes from using it deliberately.
Our assessment: AI Max is becoming the standard – the question isn't whether you get started, but how deliberately you do it. Anyone who masters brand, location, and URL controls and keeps first-party data clean turns AI automation into a genuine performance lever.

10. FAQ: The Most Important Questions About AI Max
What is AI Max for Search campaigns?
AI Max is an AI-powered extension for Google Ads Search campaigns that has been generally available since 2026. It bundles two building blocks: Search-Term Matching (which uses broad-match and keywordless technology to find relevant new search queries) and asset optimization with text customization and final URL expansion. According to Google, campaigns using the full feature set achieve an average of around 7% more conversions or conversion value at a similar CPA/ROAS.
How does AI Max differ from Performance Max?
Performance Max runs across all Google channels (Search, Shopping, YouTube, Display, Discover, Gmail, Maps) in a single campaign. AI Max remains a pure Search campaign: it extends classic Search campaigns with AI matching and AI assets, but you retain control over keywords, brand, and location settings. AI Max is thus the middle ground between keyword-based search and the fully automated black box of PMax.
Will my existing campaigns be automatically switched to AI Max?
Yes, but later than originally planned. Campaigns with Dynamic Search Ads, automatically created assets, and campaign-wide broad-match settings will be automatically switched to AI Max. After criticism from advertisers, Google postponed the automatic DSA migration from September 2026 to February 2027. Until then, you should deliberately test AI Max yourself rather than passively waiting for the switch.
Does AI Max make sense for small budgets and SMBs?
With caution. Google's performance figures come predominantly from large accounts with very high budgets, while SMBs often work with 1,000 to 5,000 euros per month. For small budgets: start small, actively set brand and URL controls, set up clean first-party tracking and GDPR-compliant Enhanced Conversions, and regularly review the AI-generated copy. AI Max doesn't replace a goal briefing – it requires one.
