What Are Performance Max Campaigns?

Step-by-Step Setup Guide

Step 1: Define Your Goals

Before creating your campaign, clearly define what you want to achieve. Performance Max supports multiple conversion goals:

  • Sales: Online purchases, in-store purchases, offline conversions
  • Leads: Form submissions, phone calls, app installs
  • Website Traffic: Increase visits to specific pages
  • Brand Awareness: Reach and video views

Step 2: Set Up Your Conversion Tracking

Accurate conversion tracking is critical for Performance Max success. Google uses conversion data to optimize your campaign delivery. Make sure you have:

  • Google Ads conversion tracking tags properly installed
  • Enhanced conversions enabled for better tracking accuracy
  • Offline conversion tracking set up if applicable

Step 3: Create Compelling Assets

Performance Max uses your assets to create ads across Google's inventory. Provide diverse, high-quality assets for best results:

  • Images: Landscape (1.91:1), square (1:1), and portrait (9:16) - at least 5-10 images
  • Videos: Short videos (under 30 seconds) showcasing products or services
  • Headlines: 3-5 headlines (up to 30 characters each) highlighting key benefits
  • Descriptions: 2-4 descriptions (up to 90 characters) with clear CTAs
  • Call-to-Actions: Include multiple CTA options like "Shop Now," "Learn More," "Sign Up"

Step 4: Define Your Audience Signals

While Performance Max finds audiences automatically, providing audience signals helps the algorithm prioritize:

  • Custom Segments: Intent signals like "running shoes" or "digital marketing services"
  • In-Market Audiences: Users actively researching or comparing products
  • Affinity Audiences: Users with long-term interests matching your offerings
  • Customer Match: Upload your existing customer lists for prospecting

Step 5: Set Your Budget and Bidding

Performance Max requires adequate budget for the algorithm to learn and optimize. As a general rule, aim for at least 15-20 conversions per month for effective optimization.

Recommended Bidding Strategies

Get the most conversions within your budget - ideal for new campaigns

Target CPA

Set a target cost per acquisition - best for stable campaigns

Target ROAS

Optimize for return on ad spend - ideal for e-commerce

Maximize Conversion Value

Get the highest conversion value - great for high-ticket items

Optimization Strategies for Maximum ROI

1

Test Multiple Asset Variations

Google automatically tests different asset combinations. Provide as many high-quality assets as possible to give the algorithm more options. Aim for 5+ images, 2+ videos, and multiple headline/description combinations.

2

Use Negative Keywords

Even though Performance Max is automated, you can add negative keywords to prevent your ads from showing for irrelevant searches. This helps improve conversion rates and reduce wasted spend.

3

Monitor Search Terms Report

Regularly review the search terms where your ads are appearing. Add irrelevant terms as negatives and create new content based on high-performing queries.

4

Leverage Brand Exclusions Carefully

If you have brand campaigns, exclude your brand terms from Performance Max to maintain control over brand messaging and avoid competing with yourself.

5

Allow Sufficient Learning Time

Performance Max campaigns need data to optimize. Avoid making changes too frequently—give the algorithm at least 2-4 weeks to learn before evaluating performance. Frequent changes can reset the learning phase.
