What is Google Performance Max?

What is Performance Max?

Performance Max stands out from other campaign types because it allows Google to take charge of targeting and delivering the ads. This means that based on the information provided by the advertiser, Google automates the process of deciding who gets to see the ads and when they are displayed.

This campaign can reach a wide audience across various Google platforms, including Search, Display, Maps, Discover Feed, YouTube, Gmail, and Shopping Ad Inventory.

When to use Performance Max

If you’re considering trying out Performance Max, be ready to spend around $50-100 per day for at least a month. Without this budget, you may not gather enough data and insights for the format to function effectively.

To use Performance Max, you have to connect your Google Ads account with your Google Merchant Center feed and include various assets like headlines, images, and videos. Google Ads will then use these elements in different combinations to create unique ads based on where they will be displayed.

Choose Google Ads Performance Max when you:

  • Have clear advertising and conversion goals (like boosting online sales or generating leads).
  • Want to optimize campaign performance without being limited to specific ad placements.
  • Prefer the convenience of using all Google advertising channels in one campaign.
  • Aim to reach a wider audience and improve conversion value beyond traditional keyword-based Search campaigns.

Pros & cons of Performance Max

Like any automated tool, this campaign format offers distinct advantages but also comes with a few trade-offs you should consider.

Pros of PMax

  • Automatic: Performance Max campaigns are entirely automated, requiring minimal ad management. This is ideal for businesses needing more time or resources to handle complex campaigns.
  • More conversions: By using additional Display-style placements, you can potentially expand your advertising reach. It can help you get more conversions by optimizing your ads across various placements and formats.

Cons of PMax

Cons of PMax
  • Limited control: Performance Max campaigns are fully automated, providing limited control over targeting and ad delivery compared to manually managed campaigns.
  • Limited insights: The campaigns lack detailed insights on specific keywords or phrases that lead to customer conversions, offering only limited information known as “top signals,” often closely tied to the brand name.

Performance Max vs. Standard Shopping

Currently, there are two options for running Shopping Ads: through a Performance Max campaign or a Standard Shopping campaign.

Now, let’s compare and evaluate these two methods.

Audience signals

Audience signals

Audience signals are directions provided by advertisers to Google regarding the desired audience for their ads. These signals are not precise targets but rather suggestions that assist the algorithm in making informed decisions. They help guide the algorithm in the right direction for effective ad targeting.

An audience signal consists of a blend of the following elements:

  • Custom segments
  • Your own audiences, including remarketing audiences and customer match lists
  • Interest and demographics, such as in-market and affinity audiences

Together, these components make up the audience signal, which aids in targeting the right audience for your ads based on specific criteria.

Assets (Ad Extensions)

Performance Max assets

Performance Max assets are the creative components incorporated into your Performance Max campaign. These assets can include text, images, or videos. This group can be based on various themes like a brand, product category, or target audience. Google Ads intelligently combines and matches the creatives within the group to effectively display them across different channels.

Google Performance Max campaign assets can be categorized into 4 types:

  • Texts
  • Images
  • Videos
  • Extensions

Performance Max benchmarks

Understanding industry benchmarks can help you set realistic expectations and evaluate campaign performance more effectively. Based on benchmark data from Lebesgue, Cassandra, here are the key metrics advertisers should monitor.

Performance Max benchmarks

Click-through rate (CTR)

Performance Max campaigns achieve an average CTR of around 1.19%. While lower than traditional Search campaigns, this is expected because PMax serves ads across Search, Display, YouTube, Gmail, Discover, and Maps.

Cost-per-click (CPC)

The average CPC for Performance Max campaigns is approximately $0.68, making it a cost-efficient option for advertisers looking to scale traffic beyond Search campaigns.

Conversion rate (CR)

Performance Max campaigns generate an average conversion rate of around 1.83%. Stronger conversion rates usually come from accurate tracking, relevant landing pages, and high-quality creative assets.

Return on ad spend (ROAS)

ROAS varies by industry, product margin, and campaign setup. According to Cassandra’s 2026 benchmark report, Performance Max campaigns deliver a median ROI of approximately 4.64x, making them a strong option for scalable eCommerce growth.

Pro Tip: Google reports that advertisers using Performance Max achieve over 18% more conversions at a similar CPA on average. Campaigns with advertiser-supplied video assets can also generate up to 12% more conversions than those relying only on automatically created videos.

How to optimize Performance Max campaigns for success

Setting up your campaign is just the first step; continuous, data-driven optimization is what separates average returns from exceptional profitability.

Structure Asset Groups by Tight Themes

Instead of dumping all your products into a single asset group, segment them tightly based on product categories, margins, or target personas. This allows you to tailor your ad copy and visuals specifically to those items, giving the machine learning algorithm hyper-relevant context to work with.

Provide High-Intent Audience Signals

Don’t just rely on broad demographic interests. Feed the algorithm your absolute best data by uploading bottom-of-funnel customer lists, such as recent purchasers or high-value subscribers. Additionally, create custom segments using high-intent search terms and URLs of your direct competitors to steer the AI toward users actively looking to buy.

Maximize and Refresh Creative Assets

To give Google’s system the flexibility to build the best ad combinations, fill every available asset slot. Upload the maximum allowed 20 images, 5 logos, and 5 videos per group. Regularly monitor the Asset Report and immediately replace assets graded as “Low” with fresh, high-quality creatives to maintain peak performance.

Exclude Brand Terms to Prevent Cannibalization

Performance Max often takes credit for conversions that would have easily come from your dedicated branded search campaigns. To get a true picture of new customer acquisition, utilize account-level negative keywords or apply Brand Exclusions in the campaign settings to stop PMax from bidding on your own brand name.

For Performance Max campaigns, brand exclusions help prevent ads from showing on queries associated with selected brands. This gives advertisers more control over branded traffic and reduces overlap with dedicated branded search campaigns.
