How to Create Performance Max Campaigns in Google Ads

Setting up a Performance Max (PMax) campaign is simple. Follow these steps:

Step 1: Choose “Performance Max” in Google Ads

  1. Go to your Google Ads account.

  2. Click + New Campaign.

  3. Select “Sales” or “Leads” as your goal.

  4. Choose “Performance Max” as the campaign type.

Step 2: Set Your Budget & Bidding

  • Daily budget: Start with at least $20-$50/day for the AI to optimize.

  • Bidding strategy: Use “Maximize Conversions” or “Target ROAS” (if you have conversion data).

Step 3: Define Audience Signals (Optional but Helpful)

Google’s AI works better if you give it hints about your ideal customers. You can add:

  • Remarketing lists (past visitors, customers).

  • Custom segments (interests, demographics).

  • First-party data (email lists from CRM).

Step 4: Add Assets (Images, Videos, Text, etc.)

This is where most advertisers struggle. Let’s break it down.

Assets Needed for Performance Max Campaigns

For PMax to work, you must provide different ad creatives. Google mixes and matches them to find the best-performing combinations.

1. Images (Performance Max Campaigns Image Size)

  • Minimum: 1 landscape (1200×628) & 1 square (1200×1200).

  • Recommended: Upload 5+ images in different sizes:

    • Landscape (1200×628)

    • Square (1200×1200)

    • Portrait (600×900 or 960×1200)

  • Format: JPG or PNG (under 5MB).

2. Videos (Optional but Highly Recommended)

  • Best size: 1920×1080 (landscape) or 1080×1920 (vertical).

  • Length: 15-30 seconds works best.

  • Format: MP4 or MOV (under 1GB).

💡 Pro Tip: If you don’t have videos, Google can create simple slideshows from your images.

3. Text Assets (Headlines & Descriptions)

  • Headlines (5 recommended, max 30 chars each).

  • Long headlines (1 recommended, max 90 chars).

  • Descriptions (5 recommended, max 90 chars each).

4. Logos (For Brand Recognition)
