Quick answer: AI Max and Performance Max are both Google Ads automation, but they are not the same thing. AI Max is a suite of AI features layered onto your existing Search campaigns to expand reach beyond your keywords. Performance Max is a separate, goal-based campaign type that runs across all of Google (Search, YouTube, Display, Gmail, Maps, Discover). Use AI Max to grow strong Search campaigns; use Performance Max to scale conversions across channels. Many advertisers run both.
The key difference most people miss
This trips up a lot of advertisers, so get it straight first:
- AI Max is a feature, not a campaign type. It is a set of AI-powered features you switch on inside your existing Search campaigns. It keeps your Search structure and uses your keywords as a starting signal, then expands beyond them with broad match and “keywordless” technology.
- Performance Max is a standalone campaign type. It is a separate, goal-based campaign that runs across every Google channel at once: Search, YouTube, Display, Discover, Gmail, and Maps.
So the real question is not “which campaign type”, it is “do I enhance my Search campaigns (AI Max), run a cross-channel machine (PMax), or both?”
Control vs automation
A useful way to see them is on a spectrum from most control to most automation:
|
Control |
Channels |
What it is |
|
|
Standard Search |
Most |
Search only |
Your keywords, your control |
|
AI Max |
Middle |
Search only |
AI features on your Search campaigns |
|
Performance Max |
Least |
All Google channels |
Automated cross-channel campaign |
With AI Max, your main control is exclusion lists, since the system expands beyond your keywords. With Performance Max, you hand Google the most control in exchange for reach and scale.

When to use AI Max
Use AI Max when you already have strong Search campaigns that have hit a ceiling and you want to capture more high-intent queries without building a new campaign type. It keeps your existing structure intact and loosens the boundaries, expanding your reach through query expansion, with exclusion lists as your guardrail. It is the natural next step for Search-led advertisers.
When to use Performance Max
Use Performance Max when you want to scale conversions across several channels at once, Search, YouTube, Display, Gmail, and Maps, from one campaign. For ecommerce and brand awareness, PMax wins on reach and scale. It suits advertisers who want Google to find customers across its whole ecosystem, not just search.
Should you run both? (The “Power Pack”)
Google’s recommended approach for advertisers who want the best of both is the “Power Pack”: run AI Max on your Search campaigns to capture high-intent queries, while Performance Max handles reach and conversion across the wider Google ecosystem.
It can work well, but with a warning. Run both without proper guardrails and they compete for the same traffic, make it harder to see what is actually driving results, and can inflate each other’s attributed conversions. If you run both:
- Separate budgets clearly.
- Use exclusions so they do not cannibalise each other.
- Monitor attribution closely so you know what is really working.
Important: the DSA migration
If you run Dynamic Search Ads (DSA), note that Google began automatically migrating DSA campaigns into AI Max from September 2026. If DSA is part of your setup, decide your campaign architecture now rather than letting the migration decide it for you.
Which is right for your business?
- Search-led, want more of the same high-intent traffic: AI Max.
- Ecommerce or brand, want cross-channel scale: Performance Max.
- Bigger budget, want both search intent and reach: the Power Pack (both), with careful separation.
- Small budget, want tight control: stick with standard Search, and test AI Max when you plateau.
There is no single winner. Match the tool to your goal, budget, and how much control you want to keep. We manage Google Ads for Malaysian businesses and set this up to fit each account.
