How to Set Up a Performance Max Campaign in Your Google Ad Grant Account

If you've read our Performance Max guide for Grant accounts and decided PMax is right for your organization, this article walks you through the exact setup process. You'll go from zero to a live PMax campaign in under an hour.

Before you begin, make sure you have:

• Active conversion tracking (at least one meaningful conversion action recording data)
• A Google Business Profile claimed and verified (if your organization has a physical location)
• 3+ images of your organization, programs, or community (landscape and square orientations)
• Your organization's logo in square format

Key Takeaways - Setup takes about 45-60 minutes including asset preparation - You need text assets (headlines, descriptions), images, and your logo - Audience signals are optional but significantly improve early performance - Set your budget to $329/day and your conversion goal to match your Search campaigns - Give the campaign 2-4 weeks to ramp up before evaluating

Step 1: Start the Campaign Creation

1. In your Google Ads Grant account, click the + New campaign button
2. Select your campaign objective. Choose the objective that matches your primary goal:

• Website traffic if awareness is your main goal
• Leads if sign-ups, form submissions, or volunteer recruitment is the goal
• Sales if donations or purchases are the goal (this works for nonprofits despite the commercial-sounding name)

1. Select Performance Max as the campaign type
2. Choose the conversion actions you want to optimize for (these should match the meaningful conversions you've set up in GA4)
3. Click Continue

Step 2: Set Budget and Bidding

Budget: Set your daily budget to $329. As with your Search campaigns, the account-level daily cap of $329 prevents overspending. Setting PMax to $329 gives Google maximum flexibility to allocate budget between PMax and Search based on where conversion opportunities exist. See our budget configuration guide for the reasoning.

Bidding: Choose Maximize Conversions as your bid strategy. If you have enough conversion data (30+ conversions in the last 30 days) and want to control cost, you can set a Target CPA. Otherwise, leave it without a target for the first month to let the algorithm learn.

If your different conversion types have different values (donations worth more than newsletter sign-ups), choose Maximize Conversion Value instead, and ensure your conversion actions have values assigned.

Step 3: Configure Campaign Settings

Campaign name: Something clear like "PMax - General" or "PMax - Local Services" so you can distinguish it from Search campaigns.

Locations: Set the same geographic targeting you use for your Search campaigns. For local organizations, target your city or metro area. For national organizations, target your country.

Languages: Set to the language(s) your target audience speaks.

Final URL expansion: Turn this OFF for your initial setup. Final URL expansion lets Google send traffic to any page on your website that it deems relevant, which can include pages that aren't aligned with your campaign goals. Once you're comfortable with PMax performance, you can experiment with enabling it later.

Automatically created assets: You can leave this on. Google will generate additional headline and description variations based on your website content. Review the auto-created assets periodically and remove any that don't represent your organization well.

Step 4: Create Your Asset Group

An asset group is PMax's equivalent of an ad group. It contains all the creative elements Google uses to build your ads. Most Grant accounts should start with one asset group and expand later.

Text Assets

Headlines (up to 15, minimum 5): Fill as many as possible. Include a mix of:

• Your organization name: "Help City Food Bank"
• Mission statements: "Feeding Families Since 2005"
• Calls to action: "Volunteer This Weekend"
• Service descriptions: "Free Groceries for Families in Need"
• Location references: "Serving Greater Portland"

Keep each headline under 30 characters.

Long headlines (up to 5, minimum 1): These are 90-character headlines used in larger ad formats:

• "Help City Food Bank Provides Free Groceries to 500 Families Every Week"
• "Volunteer With Us and Make a Difference in Your Community Today"

Descriptions (up to 5, minimum 2): 90-character descriptions that provide context:

• "We've served over 10,000 families since 2005. Find your nearest distribution center and get free groceries for your household."
• "Join 200+ volunteers making a difference every week. No experience needed. Sign up for your first shift online today."

Business name: Your organization's official name.

Image Assets

Upload at least 3 images. Google uses these for Search and Maps ad formats.

Required orientations:

• Landscape (1.91:1 ratio, recommended 1200x628 pixels): Photos of your programs in action, facilities, community events
• Square (1:1 ratio, recommended 1200x1200 pixels): Your logo or a strong program photo
• Portrait (4:5 ratio, recommended 960x1200 pixels): Optional but recommended

Image tips for nonprofits:

• Use real photos of your organization, not stock photography
• Show people benefiting from or participating in your programs (with their permission)
• Ensure images are well-lit, in focus, and represent your organization authentically
• Avoid text overlays on images (Google's system works better with clean images)

Logo

Upload your organization's logo in both square (1:1) and landscape (4:1) formats if available.

Call to Action

Select the most appropriate CTA from Google's options. For most nonprofits, "Learn more," "Sign up," "Get involved," or "Donate" work well. You can also select "Automated" to let Google choose the best CTA based on context.

Step 5: Set Audience Signals

Audience signals tell Google's AI who your ideal audience looks like. They're optional but significantly improve early performance by giving the algorithm a head start.

Search themes: Add 5-10 search terms that describe what your audience might search for. For a food bank: "food bank near me," "free groceries," "food assistance," "hunger relief," "emergency food."

Interests and demographics: Select relevant categories:

• In-market audiences: People actively researching topics related to your cause
• Affinity audiences: People with long-term interests aligned with your mission (e.g., "Charity and Philanthropy," "Green Living Enthusiasts")
• Custom segments: Create a segment based on URLs your audience might visit (competitor nonprofits, cause-related websites)

Your data: If you have a customer list (email list of donors, volunteers, or supporters), you can upload it as a customer match audience. Google uses this to find similar people.

Remember: audience signals are suggestions, not restrictions. Google's AI may (and should) find audiences beyond your signals as it learns.

Step 6: Review and Launch

Before clicking "Publish":

1. Review all assets: Are headlines accurate? Do images represent your organization well?
2. Verify conversion actions: The campaign should be optimizing for the same meaningful conversions as your Search campaigns
3. Check geographic targeting: Does it match your organization's service area?
4. Confirm Final URL expansion is OFF (for initial launch)
5. Confirm budget is $329/day

Click Publish campaign.

What to Expect After Launch

Week 1-2 (Learning phase): Performance will be inconsistent. Spend may be low initially as the AI explores different audiences and placements. This is normal. Don't make changes during this period.

Week 3-4 (Ramping up): The AI has enough data to start optimizing. Spend should increase and conversion costs should become more consistent. Review the Insights tab for search terms and audience segments that are performing well.

Month 2+: PMax should be contributing steady conversions alongside your Search campaigns. Monitor weekly and make adjustments monthly (new images, updated headlines, refined audience signals).

Performance check: After 4 weeks, compare PMax's cost-per-conversion to your Search campaigns. If PMax is significantly more expensive with lower-quality conversions, consider reducing its budget or pausing. If it's competitive or better, increase investment.

Common Setup Mistakes to Avoid

Launching without conversion tracking. PMax cannot optimize without conversion data. If your tracking is missing or broken, PMax will underperform dramatically. Fix conversion tracking first.

Using only one or two headlines. The more text assets you provide, the more combinations Google can test. Fill as many headline and description slots as possible.

Enabling Final URL expansion on day one. This lets Google send traffic to any page on your site, which may include pages that aren't relevant to your campaign goal. Disable it initially and enable later once you're confident in PMax performance.

Judging performance too early. PMax needs 2-4 weeks to ramp up. Making changes during the learning phase resets the algorithm's progress.

Running PMax without a Search campaign alongside it. PMax and Search complement each other. Search captures high-intent keyword traffic; PMax finds additional audiences through Maps and AI-driven targeting. Run both.

Frequently Asked Questions

Do I need a video for PMax in a Grant account? No. Since Grant PMax only runs on Search and Maps (not YouTube), video assets aren't required. You can skip the video upload during setup.

How many asset groups should I create? Start with one. Once you have performance data (after 4+ weeks), you can create additional asset groups for different themes (e.g., one for donations, one for volunteer recruitment) with distinct images and messaging for each.

Can I see which search terms triggered my PMax ads? PMax provides limited search term visibility compared to Search campaigns. Check the Insights tab for search themes and top-performing search categories. For full keyword control, continue running Search campaigns alongside PMax.

Should I pause my Search campaigns when launching PMax? No. Keep your Search campaigns running. PMax and Search operate in the same auction, but Google's system manages the interaction. Your Search campaigns provide keyword control and CTR compliance, while PMax adds Maps and AI-driven reach.

Does PMax work for nonprofits without a physical location? Yes, but you'll miss out on Maps placements. PMax will still run Search ads using its AI-driven targeting. However, the unique benefit of PMax for Grant accounts is Maps, so organizations without physical locations get less incremental value compared to running strong Search campaigns.
