Performance Max (PMax) campaigns were introduced by Google in November 2021 as a next-generation campaign type designed to streamline and enhance advertising efforts.
Built with automation at its core, PMax campaigns enable advertisers to reach audiences across Google’s vast ecosystem, providing a unified approach to ad management and optimisation.
This campaign type represents a significant shift towards leveraging machine learning and audience insights to maximise ad performance.

What is a Performance Max Campaign?
A Performance Max campaign is a goal-based advertising campaign type that utilises Google’s machine learning technology to optimise performance across all Google platforms, including Search, Display, YouTube, Discovery, Gmail, and Maps.
Key Differences from Other Campaign Types:
- Unlike traditional Search campaigns, which rely on manual keyword targeting, PMax campaigns prioritise intent-based targeting driven by audience signals and machine learning.
- PMax campaigns consolidate multiple campaign types into one, enabling advertisers to manage ads for different Google properties under a single umbrella.
- Display campaigns offer broad reach with the ability to exclude specific placements, while Performance Max offers less manual control over ad placements, instead relying on machine learning to optimise for specific objectives – however, soon, you’ll be able to exclude specific age groups and target devices like desktops only, offering more precise audience control.
The Benefits of Performance Max Campaigns
1. Complements Existing Search Campaigns
PMax campaigns can work effectively alongside Search campaigns, with exact match search keywords taking precedence. To ensure there’s no keyword cannibalisation of your search campaigns, use search themes cautiously (as these act like broad match keywords). Although, a recent update has added a usefulness indicator, revealing how search themes expand reach or overlap with other campaigns.
Advertisers can also now add up to 100 negative keywords directly in PMax campaigns. While helpful, the limit is restrictive – using the Performance Max Modification Request Form allows up to 5,000 negative keywords to be added.
2. Advanced Machine Learning and Audience Signals
PMax leverages sophisticated audience signals to identify and target users who are most likely to engage with your ads. For example, if you’re promoting a leisure activity, PMax can focus on users with a high likelihood of booking activities similar to yours. Google also now uses Customer Match data to optimise for high-value customers.
3. Cross-Platform Reach
Ads created in PMax campaigns are eligible to appear across all Google platforms, offering expansive visibility.
- Google Search: For intent-based queries.
- YouTube: Captivating video ads.
- Google Display Network: Engaging visual ads on relevant websites.
- Discovery: Highly visual, native-style ads.
- Gmail and Maps: Increasing touchpoints with users.
Limitations of Performance Max Campaigns
1. Dependency on High-Quality Creative Assets
The success of PMax campaigns heavily depends on the quality of the images, videos, and headlines provided. Poor creative assets can lead to higher costs and reduced effectiveness.
2. Reduced Transparency
Advertisers have less visibility into individual performance metrics, such as which specific platforms or placements are driving conversions. However, Google has been listening to feedback and gradually adding more visibility to the workings of your campaign – such as the source of search terms (from keywordless targeting or search themes), and enhanced asset group reporting, broken down by device and time.
3. Limited Manual Controls
PMax campaigns prioritise machine learning, which reduces the advertiser’s ability to manually fine-tune targeting or exclude certain audiences beyond the available options. For advertisers that are less confident with Google Ads, this could be an advantage.
4. Budget Overlap
PMax campaigns can overlap with other Google campaigns, potentially causing internal competition for ad spend. Due to this, you need to be cautious of how you’re using Performance Max campaigns to avoid cannibalisation.
Uses of Performance Max Campaigns
Performance Max campaigns can be used in a variety of contexts to drive significant results
E-commerce Promotion
Retailers can showcase their products across Google’s platforms, including Search, Shopping, YouTube, Display, Discover, Gmail, and Maps, to drive online sales.
Lead Generation
Businesses aiming to collect leads can utilise PMax campaigns to reach potential clients across various channels, optimising for actions like form submissions or enquiries.
Brand Awareness
By displaying ads on platforms like YouTube and Display, companies can increase brand visibility and recognition among a broad audience. From advertiser feedback, you can now apply brand exclusions specifically to search traffic, allowing more flexibility in managing branded and non-branded campaigns.
Local Store Promotion
Businesses with physical locations can use PMax campaigns to drive foot traffic by promoting their stores across Google Maps and local search results.
New Product Launches
When introducing new products, advertisers can leverage PMax campaigns to reach a wide audience quickly, helping the product gain visibility across multiple platforms.
Google Ad Grant Account PMax Campaigns
Google introduced PMax campaigns for Ad Grant accounts during 2024, allowing charities to take advantage of this innovative campaign type.
PMax campaigns in Google Ad Grant accounts have many of the same benefits as it does in paid settings. However, they currently only appear in the search results for Google Grants, with the potential of being rolled out to other Google-owned properties, such as Maps, Shopping or maybe Gmail in the future.
Tips for Charities Using PMax Campaigns:
- Leverage audience signals to focus on relevant demographics.
- Ensure high-quality creative assets to meet the programme’s performance criteria.
- Regularly review campaign performance and adjust goals to align with your organisation’s mission.
Summary
Performance Max campaigns are a game-changer for advertisers, offering a streamlined, data-driven approach to digital advertising.
By complementing existing campaigns, maximising cross-platform reach, and leveraging machine learning, PMax campaigns provide a powerful tool for businesses and non-profits alike.
While there are limitations, such as reduced transparency and reliance on quality assets, the benefits often outweigh the challenges.
