What is Performance Max (PMax) campaign?
Performance Max (PMax) is a goal-based Google Ads campaign that uses automation to show your ads across all Google channels from one single campaign.
Instead of creating separate campaigns for Search, Display, YouTube, Discover, Maps, and Gmail, PMax combines everything and uses Google’s machine learning to find the best placements and audiences for your goals.
For beginners, the simplest way to understand PMax is this:
You give Google your goals, budget, creative assets, and audience signals, and the system automatically finds the people most likely to convert. It continuously tests different combinations of headlines, images, videos, placements, and audiences to improve performance over time.
Performance Max is rather useful if you want more conversions, a broader reach, and automated optimization without manually managing multiple campaign types.
However, because it’s highly automated, you get less control over specific keywords or placements — the system does most of the decision-making for you.
How does Performance Max, PMax campaign work?
Performance Max works by using Google’s AI to automatically find the best places and audiences for your ads across all Google channels.
You provide your goals, budget, and creative assets (texts, images, videos), then PMax tests different combinations and placements to see what drives the most conversions.
It uses real-time signals, like user behavior, search intent, and device, to decide when and where to show your ads.
So basically, you set the direction, and PMax handles the targeting, bidding, and placement to get you the best possible results.

Pmax bidding strategies
Performance Max uses two primary bidding strategies, both of which are focused on conversions.
You can choose Maximize Conversions (with or without a target CPA) or Maximize Conversion Value (with or without a target ROAS).
These bidding options let Google’s AI automatically adjust bids based on real-time signals, like user behavior, time of day, device, and intent, to get the best results for your goal.
In simple terms: you tell Google whether you want more conversions or more value, and PMax optimizes bids across all channels to achieve that outcome.
What assets are needed in a PMax campaign?
A Performance Max (PMax) campaign requires a mix of creative assets so Google’s AI can build and test different ad combinations across Search, Display, YouTube, Discover, Maps, Gmail, and Shopping.
You’ll need headlines, long headlines, descriptions, images in various sizes, logos, and ideally at least one video (otherwise Google will auto-generate one).
You can also add audience signals, a final URL, extensions, and product feeds if you’re running eCommerce. These assets help PMax create responsive ads tailored to each placement and user intent.
TLDR: What to prepare for a PMax campaign:
- A conversion-focused goal (sales, leads, store visits, etc.)
- Budget: A Daily or monthly budget is required
- Location: Set your target countries/regions
- Headlines & descriptions
- Images & logos
- Videos (optional but highly recommended)
- A clear landing page
- Conversion tracking
- Audience Signals (Optional)
What are audience signals?
Audience signals are hints you give to Google to help Performance Max understand who your ideal customers are. They don’t limit your targeting, but they guide the algorithm’s starting point, so Google can learn faster and expand toward people who look similar or show strong conversion intent.
Audience signals vs. audience targeting
Audience targeting lets you directly choose who you want to show ads to, while audience signals simply guide Google’s algorithm on where to start. In Performance Max, signals are suggestions—not restrictions—so Google can still reach people outside your defined audiences if they’re likely to convert.
What is a lookalike segment/ audience?
A lookalike audience is a group of new users who share similar traits, behaviors, or interests with your existing customers. Google identifies these people using patterns found in your audience signals, helping you reach users who are more likely to convert even though they’ve never interacted with your brand before.

PMax optimizes across Search, YouTube, Discover, Maps, Gmail, and Display for conversions, while Display campaigns give you more manual control over placements, audiences, and bidding, but only on visual ad inventory.

PMax uses automation to decide when and where to show your assets for conversions, while Video campaigns give you more control over video formats, placements, and targeting specifically within YouTube’s ecosystem.

Performance Max focuses on driving conversions across all Google channels using full automation, while Demand Gen is designed for visually rich ads aimed at generating interest and engagement across YouTube, Discover, and Gmail.
PMax is conversion-driven and broad, whereas Demand Gen is more creative-focused and ideal for mid-funnel campaigns like discovery, engagement, and remarketing.
If I want my ad to appear on Google Maps or Waze, will PMax deliver that? Especially for a local store business.
Yes — Performance Max can show your ads on Google Maps if your campaign is set up with a store-related goal, but it will not show ads on Waze.
For local businesses, PMax can trigger local inventory ads, directions-based ads, and map-based visibility as long as you have a connected Google Business Profile and have enabled location extensions.
However, Waze ads are separate and require a different platform (Waze Ads Manager), so PMax won’t deliver there.
