Decoding Performance Max Campaigns
Introduced to all Google Ads accounts in 2021, Google’s Performance Max campaigns, often referred to as PMax, are a relatively recent addition. This automated, cross-channel campaign type allows you to showcase ads across Google’s entire ad network through a single campaign, encompassing Search, Display, YouTube, Discover, Maps, and Gmail.
These campaigns function by first identifying your objective. Then, much like creating a responsive display ad, you provide assets such as images, videos, logos, headlines, descriptions, and more. Previewing your ads offers a glimpse into their final appearance. Upon launching the campaign, Google, leveraging machine learning, dynamically generates and displays ads across suitable channels whenever they are eligible. This ensures that the right ad is shown at the right time with the optimal bid to maximize your goal.
Weighing the Pros and Cons of Performance Max Campaigns
Performance Max, like all campaign types, has its strengths and weaknesses.
Advantages of PMax
- Full automation empowers Google to handle the heavy lifting, but you retain the ability to guide automation and influence performance through the assets and Audience Signals you provide.
- Expanded reach allows you to connect with new audiences across all of Google’s channels.
- Goal-oriented campaigns make them well-suited for e-commerce and lead generation businesses.
Disadvantages of PMax
- Comprehensive conversion tracking is essential. This is not only a technical requirement due to the campaign type’s functionality but also crucial for evaluating and improving performance.
- Automation’s trade-offs: While automation can reduce your workload, it comes with inherent compromises. You relinquish control over various campaign aspects typically managed meticulously in standard Google Ads campaigns, including ad placement, creative combinations, keywords, and search queries.
- Limited customer segmentation: PMax campaigns lack insights into remarketed versus new customers or brand versus non-brand interactions within a campaign.
- Extensive creative demands: Performance Max campaigns thrive on a wealth of creative elements and assets. To maximize this campaign type, you’ll need to upload an ample amount.

Ten Effective Ways to Optimize Your Performance Max Campaigns
Despite their automated nature, numerous strategies can be employed to optimize your Performance Max campaigns for peak performance. Let’s explore them.
1. Dedicate Sufficient Resources to Your Campaigns
PMax campaigns, being fully automated, require significant data and machine learning to reach their full potential. Be ready to allocate a minimum budget of $50-100 per day for at least one month. In fact, Google suggests at least 6 weeks to allow the machine learning algorithm to adapt and gather enough data for performance comparisons.
2. Maximize Asset Uploads
The more assets you incorporate, the better. This expands your ad’s reach by increasing its eligibility across various ad inventories. Note that if you’re using a Merchant Center feed, uploading product images is unnecessary. Instead, focus on lifestyle or brand creatives that complement the product feed images. If your sole focus is running Google Shopping campaigns, refrain from adding any assets and rely solely on your feed. This approach ensures that your campaign delivers Shopping ads alongside Display and YouTube ads, but the latter two will also be in Shopping format.

3. Understand the Nuances and Workarounds
While we’ve dedicated a comprehensive post to Performance Max’s best practices, pitfalls, and workarounds, some are worth reiterating:
- Bidding: The bidding strategy choices are limited to either Maximize conversions or Maximize conversion value, aligning with Performance Max campaigns’ conversion-centric nature.
- Location settings: By default, PMax location settings, like other campaigns, are set to “Presence or interest.” Switch to “Presence only” if your target audience is solely within that location.
- Audience signals: In PMax campaigns, you don’t target a specific audience directly. Instead, you provide “Audience Signals” that act as a starting point for Google, akin to optimized targeting.
- URL expansion: PMax automatically enables URL expansion. This feature, similar to Dynamic Ads, allows Google Ads to direct users to landing pages other than your designated final URL. Deactivate this feature if it conflicts with your goals. Alternatively, leave it active but utilize URL exclusions.

4. Leverage the Customer Acquisition Feature
This feature, exclusive to Performance Max campaigns, empowers you to choose whether the campaign targets new and existing customers or focuses solely on acquiring new users.

5. Optimize Your Asset Groups
When setting up a Performance Max campaign, you’ll place all your assets within an asset group. An asset group is a collection of creative elements that dynamically form an ad based on the channel where it’s displayed. It’s recommended to organize asset groups by a shared theme, similar to ad group organization. Once the campaign is running, you can revisit and add more asset groups. Structure them logically for your business, such as separating them by products or services offered.
6. Implement Campaign Exclusions
Utilize campaign exclusions to minimize wasted ad spend and enhance campaign efficiency. This includes:
- Product exclusions: According to DataFeedWatch’s 2022 Feed Marketing Report, approximately 17% of products in advertising catalogs are unavailable for purchase, making them prime candidates for catalog exclusions.
Excluding product variations relevant to the same search query, low-profit or low-margin products, and products with low conversion rates is also advisable. Utilize Listing Groups and exclude these products based on Brand, Product ID, Category, Custom Labels, and more.
Besides boosting campaign efficiency, these exclusions streamline the learning phase for Google by reducing the number of products it needs to process.
- Keyword exclusions: Implement negative keywords to prevent budget allocation to irrelevant searches.
- Existing customers: As mentioned earlier, you can exclude existing customers, directing your Performance Max campaign’s focus solely toward new customer acquisition. Select the “Only bid for new customers” checkbox during campaign setup.
7. Select the Optimal Bidding Strategy
Two bidding options are available when initiating a new Performance Max campaign:
- Maximize Conversions to generate the highest conversion count for your budget.
- Maximize Conversion Value to prioritize conversions with higher value. This strategy may result in fewer conversions, but they should, in theory, hold greater value. Once your campaign accumulates sufficient conversion data, experiment with either Maximize Conversions with Target CPA or Maximize Conversion Value with Target ROAS bid strategies to further elevate your campaign.
While you can opt for Target CPA or Target ROAS from the start, gathering substantial conversion data when launching a new campaign is recommended.
8. Integrate Ad Extensions
Google Ads extensions (now called assets) expand your ad space and enhance its relevance and allure by incorporating supplementary information. While 14 ad extensions are available—including reviews, locations, call, pricing, promotion, and more—always consider these:
- Sitelinks emphasize and direct users to other relevant pages. For instance, you could link to an about us page, highlight pertinent product categories, a pricing page, and more. The possibilities are vast, and they significantly impact your ad visually. Google suggests that using the recommended minimum of four sitelinks alone can advertisers can see a 20% increase in click-through rate on average through this single ad extension.
- Callouts are concise information snippets, each limited to 25 characters, ideal for emphasizing selling points or key USPs. Aim to include at least eight callouts.
- Structured snippets highlight specific products, services, or features in a list format. For example, a bag retailer might use a Product Structured Snippet to showcase clutch bags, handbags, tote bags, backpacks, messenger bags, and card wallets. To illustrate the impact of ad extensions, here’s an example of a Search ad displayed without any:
In contrast, here are two other Search ads from the same auction, showcasing multiple ad extensions. The Wolf and Badger ad features sitelinks, a promotion extension, and a location extension, while the Cambridge Satchel ad incorporates sitelinks, a location extension, a review extension, and a price extension.

9. Ensure Your Data Feed Is in Top Shape
This point is crucial for advertisers submitting products via a data feed who utilize the Merchant Centre. Include comprehensive information in your feed, ensuring it’s current and relevant. Pay close attention to these vital product identifiers. The first three help Google comprehend your offerings, while the last three are equally critical for optimization:
- Brand name
- Manufacturer part number (MPN or SKU)
- UPC code (aka GTIN)
- Descriptive titles
- Google taxonomy/categorization
- Product type Your data feed forms the bedrock of your PMax campaign, influencing results more than any other element.

Consider implementing a data feed management solution to maximize e-commerce advertising and particularly Performance Max campaigns. Feed management tools simplify and automate the intricacies of feed management, ultimately enhancing online visibility, boosting conversion rates, and improving ROAS.
According to the previously mentioned Feed Marketing Report, these tools are even more valuable for specific e-commerce sectors—such as automotive, fashion, and home & garden—that grapple with complex data feed management due to their extensive product catalogs and variations.
10. Fine-Tune Your Audience Signals
If, after a reasonable period, your Performance Max campaigns aren’t yielding the desired outcomes, revisit your Audience Signals. Refine them by using your own business data, prioritizing it over Google’s interest-based options, including in-market and affinity audiences.
- Customer lists, if you possess ample customer data and consent to utilize it for advertising, should be your top choice. These lists are powerful because they leverage your actual customer data to identify potential new customers.
- Customer intent audiences refine Google’s interest-based targeting by incorporating relevant keywords.
- Website visitor audiences are also valuable, especially if you lack access to customer lists. Consider creating an audience signal based on website visitors or even website converters. While Google’s interest-based audiences remain a viable option, explore the approaches mentioned above to enhance your Audience Signals further.
