Google Ads Performance Max: 2026 Agency Wins

Listen to this article · 15 min listen

Mastering the intricacies of digital advertising platforms is what truly separates a good marketing team from an exceptional one. For advertising agencies, understanding the nuanced settings within tools like Google Ads isn’t just about efficiency; it’s about delivering measurable ROI and staying competitive in a rapidly evolving market. Today, we’re going to break down how to set up a high-performing Performance Max campaign in Google Ads, focusing on real-world UI elements and strategies that drive results.

Key Takeaways

  • Performance Max campaigns require a minimum of 20 high-quality text assets, 5 image assets (at least one landscape, one square), and 1 video asset for optimal ad serving and platform learning.
  • The “Final URL Expansion” setting, found under Campaign Settings > More Settings, significantly impacts traffic quality; disabling it directs users only to precise landing pages, while enabling it allows Google to find relevant pages across your site.
  • Audience Signals, accessible during campaign setup under “Audiences,” are critical for guiding Google’s AI, and should include custom segments based on competitor URLs and high-intent search terms.
  • Budget allocation for Performance Max should be at least $50/day for the first two weeks to allow the algorithm sufficient data to exit the learning phase effectively.
  • Monitoring the “Insights” tab within your Performance Max campaign is essential for identifying top-performing assets and understanding audience behavior, informing iterative optimizations.

Step 1: Initiating Your Performance Max Campaign

Starting a new campaign in Google Ads can feel like navigating a labyrinth, but Performance Max campaigns, despite their complexity under the hood, have a surprisingly straightforward setup process. My first piece of advice? Don’t rush this step. A solid foundation here dictates the campaign’s success.

1.1 Accessing the Campaign Creation Interface

  1. From your Google Ads dashboard, look to the left-hand navigation pane. You’ll see a prominent “Campaigns” option. Click it.
  2. Once on the Campaigns overview page, locate the large, circular “+ New Campaign” button. It’s usually blue or green and positioned clearly, often at the top of the campaign list or directly under the main “Campaigns” heading. Give that a click.
  3. Google will then present you with a list of campaign objectives. This is where many new users falter, picking the wrong goal. For most Performance Max campaigns, especially when you’re focused on driving conversions, select “Sales” or “Leads.” While other options exist, these two give the algorithm the clearest signal for optimization.
  4. After choosing your objective, Google will ask you to “Select a campaign type.” Here, you’ll see “Performance Max” listed prominently. Select this option. If you don’t see it, double-check your objective selection; some objectives (like “App promotion”) default to specific campaign types.

Pro Tip: Always start with “Sales” or “Leads” for Performance Max if you have conversion tracking properly set up. The algorithm is designed to find users most likely to convert, and these objectives align perfectly with that goal. If you’re just looking for brand awareness, Performance Max isn’t your best bet anyway – go with a display or video campaign.

1.2 Configuring Conversion Goals

Before proceeding, Google will prompt you to “Select the conversion goals you’d like to use for this campaign.” This is absolutely critical. I’ve seen countless campaigns underperform because agencies didn’t refine their conversion goals here. By default, Google often includes every conversion action tracked in your account. That’s usually a mistake.

  1. Review the list of “Account-default goals.”
  2. Uncheck any goals that are not directly tied to the primary objective of this specific Performance Max campaign. For instance, if you’re selling products, keep “Purchases” and maybe “Add to Cart,” but deselect “Page views” or “Contact page visits” unless they are direct micro-conversions you want to optimize for.
  3. If your primary conversion isn’t listed, or you need to add a new one, click “Add another goal.” This will take you to the “Conversions” section of your account where you can define new conversion actions.

Common Mistake: Leaving all default conversion goals enabled. This dilutes the algorithm’s focus. If you’re telling Google to optimize for 10 different things, it won’t be great at optimizing for any single one. Be ruthless here.

Step 2: Setting Campaign Budget and Bidding Strategy

This is where the rubber meets the road. Your budget and bidding strategy directly impact how Google finds and attracts potential customers. Get this wrong, and your marketing budget will evaporate faster than ice cream in August.

2.1 Defining Your Daily Budget

  1. On the “Set your budget and bidding” screen, enter your “Average daily budget.”
  2. For Performance Max, especially in the initial learning phase, I recommend a minimum of $50 per day for most small to medium businesses. For larger enterprises, this should be significantly higher. Why? The algorithm needs data – significant data – to learn and optimize effectively. A paltry budget starves the system.

Editorial Aside: Many clients balk at higher starting budgets, fearing wasted spend. But here’s what nobody tells you: underfunding a Performance Max campaign during its first 1-2 weeks is almost guaranteed to lead to poor results, making you think the campaign type itself is flawed. It’s not; your budget was too low for the AI to do its job. It’s like trying to teach a child to read with only three words – they just won’t get enough context.

2.2 Selecting a Bidding Strategy

Google offers several bidding strategies, but for Performance Max, the choices are more streamlined, focusing on automated bidding. As of 2026, the options are typically:

  1. Maximize Conversions: This is the default and often the best choice for Performance Max. It tells Google to get you as many conversions as possible within your budget.
  2. Maximize Conversion Value: If you have conversion values assigned (e.g., different products have different prices), this strategy will prioritize conversions that generate the most revenue. This is fantastic for e-commerce.
  3. You’ll then have the option to set a “Target cost per action (CPA)” or “Target return on ad spend (ROAS).”

Pro Tip: For new campaigns, start with “Maximize Conversions” without a target CPA. Let the campaign run for 2-3 weeks to gather data and establish a baseline CPA. Only then should you consider adding a Target CPA, making sure it’s realistic based on your initial performance. Setting an unrealistic target CPA too early will stifle your campaign’s reach and learning.

Step 3: Campaign Settings and Advanced Options

This section contains critical settings that can make or break your campaign, yet they are often overlooked. Pay close attention here; these aren’t just checkboxes.

3.1 Location and Language Targeting

  1. Under “Locations,” choose your target regions. You can select countries, states, cities, or even specific zip codes. For a local business in Atlanta, for example, I’d target “Atlanta, Georgia, United States” and then use “Location options (advanced)” to refine.
  2. In “Location options (advanced),” you’ll see two radio buttons under “Target”:
    • Presence or Interest: People in, regularly in, or who’ve shown interest in your targeted locations (recommended)
    • Presence: People in or regularly in your targeted locations

    For most local businesses, I strongly recommend choosing “Presence.” The “Presence or Interest” option can lead to wasted spend showing ads to people far away who merely searched for your city once.

  3. Next, under “Languages,” select the languages your target audience speaks. If you’re targeting English speakers in the US, stick to “English.”

Anecdote: I had a client last year, a boutique law firm specializing in personal injury in Fulton County, Georgia, who initially had “Presence or Interest” enabled. They were getting clicks from people in California who had simply Googled “Atlanta personal injury lawyer” once. Switching to “Presence” immediately dropped their irrelevant traffic by 30% and improved their conversion rate by 5% within a month. It’s a small change with huge impact.

3.2 Final URL Expansion and Brand Exclusions

  1. Navigate to “More settings” within the Campaign Settings.
  2. Find “Final URL expansion.” This setting determines whether Google can send users to any relevant page on your website or only to the specific URLs you provide in your asset groups.
    • On (recommended)“: Google can use AI to find the most relevant landing page on your site. This is often good for broad e-commerce or lead generation where users might convert on various pages.
    • Off: Only send traffic to the URLs you’ve provided“: This gives you tight control. If you have very specific landing pages for specific offers, or you’re concerned about sending users to irrelevant blog posts, turn this off. I almost always turn this off for lead generation campaigns unless the client has a perfectly optimized site where every page is a potential conversion point.
  3. Below that, you’ll find “Brand exclusions.” This is a newer feature in 2026 and a godsend for agencies. Click “Add brand exclusions.” Here, you can prevent your ads from showing up for specific brand terms. This is crucial for protecting your brand’s reputation and preventing ads from showing next to unsavory content. Add your own brand name and any other brands you absolutely want to avoid appearing with.

Expected Outcome: By carefully configuring these settings, you ensure your ads reach the right audience, on the right pages, and avoid brand safety issues.

Step 4: Building Your Asset Groups

Asset groups are the heart of Performance Max. They combine your creative assets (text, images, videos) with your audience signals, allowing Google’s AI to dynamically assemble ads across all its inventory (Search, Display, YouTube, Gmail, Discover). Think of each asset group as a mini-campaign targeting a specific theme or audience segment.

4.1 Naming and Final URL

  1. Give your asset group a clear, descriptive name (e.g., “Winter Collection – New Customers” or “Emergency Plumbing Services – Atlanta“).
  2. Enter your “Final URL.” This should be the most relevant landing page for this specific asset group. If you turned off “Final URL expansion” in Step 3, this is the ONLY page Google will send traffic to for this group.

4.2 Adding High-Quality Assets

This is where quality truly matters. Google’s AI is powerful, but it needs good inputs. Shoddy assets will lead to shoddy results.

  • Images (Min. 5, Max. 20):
    • Landscape (1.91:1): At least one. Recommended size: 1200 x 628 px.
    • Square (1:1): At least one. Recommended size: 1200 x 1200 px.
    • Portrait (4:5): One is ideal for mobile display. Recommended size: 960 x 1200 px.
    • Logos (1:1 & 4:1): Upload both square (1200 x 1200 px) and landscape (1200 x 300 px) versions of your logo.

    Pro Tip: Use high-resolution, professional images. Avoid stock photos that look generic. Show your product in use, happy customers, or unique selling propositions. According to Nielsen data, compelling visuals can increase ad recall by up to 20%.

  • Videos (Optional, but highly recommended):
    • Upload at least one video (max 5). If you don’t provide one, Google will auto-generate one, which is rarely good.
    • Aim for videos between 15-30 seconds. They should be engaging, convey your message quickly, and have a clear call to action.

    Common Mistake: Skipping video. Performance Max leverages YouTube heavily. No video means you’re missing out on a massive, engaged audience. Even a simple slideshow with voiceover is better than nothing.

  • Headlines (Min. 3, Max. 5 short; Min. 3, Max. 5 long):
    • Short headlines (up to 30 characters): Write compelling, concise headlines.
    • Long headlines (up to 90 characters): Provide more detail, incorporating keywords.
  • Descriptions (Min. 2, Max. 5):
    • Short description (up to 60 characters): A quick selling point.
    • Long descriptions (up to 90 characters): Elaborate on benefits, features, or offers.
  • Business Name & Call to Action:
    • Enter your “Business name.”
    • Select a relevant “Call to action” (e.g., “Shop Now,” “Learn More,” “Get Quote”).

4.3 Leveraging Audience Signals

This is arguably the most powerful part of Performance Max. Audience signals tell Google’s AI who your ideal customer is, giving it a head start in finding them. Without good signals, the AI is effectively flying blind for a while.

  1. Under “Audience signals,” click “Add an audience signal.”
  2. Custom Segments: This is my go-to.
    • Click “+ New Custom Segment.”
    • Create segments for “People who searched for any of these terms” using your top-performing keywords from previous search campaigns, as well as competitor brand names.
    • Create segments for “People who browsed types of websites” by adding competitor URLs. This helps Google find users with similar interests.
  3. Your Data (Remarketing Lists): Upload and include any customer lists (email lists) you have, and leverage your website remarketing lists. This is incredibly effective.
  4. Interests & Detailed Demographics: Add relevant interests and demographic information. If you’re selling high-end furniture, target “Luxury goods” or “Interior design.”

Case Study: We recently launched a Performance Max campaign for a regional auto repair chain, “Atlanta Auto Works,” with three locations across the perimeter highway. Our initial asset group included generic auto repair images and broad audience signals. Performance was mediocre. We then created a new asset group, focusing on “European Car Repair” – we used images of BMWs and Mercedes, headlines like “Expert BMW Service in North Atlanta,” and our audience signals included custom segments for “Mercedes-Benz Atlanta” and “BMW repair near me.” We also uploaded a customer list of previous European car owners. Within two weeks, the CPA for this specific asset group dropped by 35% compared to the generic group, and the conversion volume increased by 2x. This demonstrates the power of highly specific asset groups and strong audience signals.

Step 5: Review and Launch

You’re almost there! Don’t skip the review process; it’s your last chance to catch errors.

5.1 Final Review

  1. Google will provide a comprehensive “Review your campaign” page. Read through every section carefully.
  2. Check your budget, bidding strategy, location targeting, and especially your asset groups. Ensure all required assets are present and look good.
  3. Look for any “Warnings” or “Recommendations” from Google. Sometimes these are generic, but sometimes they highlight genuine issues like missing assets or conflicting settings.

5.2 Publishing Your Campaign

  1. Once you’re satisfied, click the prominent “Publish Campaign” button.
  2. Your campaign will go into a “Pending” or “Under Review” status as Google checks your ads for policy compliance. This usually takes a few hours, but can sometimes be longer.

Expected Outcome: A live Performance Max campaign, ready to enter its learning phase. Remember, initial performance might be volatile. Give it at least 2-3 weeks to stabilize and gather data before making significant changes.

Launching a Performance Max campaign isn’t just about clicking buttons; it’s about strategic asset creation, precise targeting through audience signals, and thoughtful budget allocation. By following these steps and leveraging the nuanced settings within Google Ads, advertising agencies can build powerful, conversion-driving campaigns that deliver real results for their clients, proving their expertise in a competitive digital landscape.

What is the optimal number of assets for a Performance Max campaign?

For optimal performance and to give Google’s AI enough variations, aim for 20 unique text assets (headlines and descriptions), 20 image assets (including landscape, square, and portrait), 5 logos, and at least 1-2 high-quality video assets per asset group.

How long does it take for a Performance Max campaign to optimize?

Performance Max campaigns typically require 2-3 weeks to exit the initial learning phase and stabilize. During this period, the algorithm gathers data to understand your target audience and optimal placements. Avoid making significant changes during this phase.

Should I use a Target CPA or Target ROAS strategy from the start?

For new Performance Max campaigns, it’s generally better to start with “Maximize Conversions” without a target CPA or ROAS. This allows the algorithm to learn unimpeded. After 2-3 weeks of data, you can then introduce a realistic target based on your campaign’s actual performance.

What is the “Final URL expansion” setting, and when should I turn it off?

Final URL expansion allows Google to send users to any relevant page on your website, not just the one you specify. Turn it “Off” if you have very specific landing pages for your offers and want strict control over where traffic is directed, preventing users from landing on less relevant pages like blog posts.

Can I exclude certain placements or keywords in Performance Max?

While Performance Max is largely automated, you can use “Brand exclusions” to prevent your ads from showing for specific brand terms. For broader negative keywords or placement exclusions, you’ll need to contact Google Support or your account representative to implement account-level negative keywords or placement lists, as these aren’t directly configurable within the campaign UI.
