Performance Max assets best practices

Performance Max campaigns have gained significant popularity among other ad types due to their ability to reach a broader audience across various Google platforms. They utilize machine learning and automated bidding to optimize ad placements and achieve the best possible performance.

To improve the effectiveness of Performance Max campaigns, it is essential to keep in mind some key considerations when creating assets:

Add as many assets as you can

The more different creative elements you offer to Google's algorithm, the more ad placements you will have, and Google can better test their effectiveness. So don't go for the bare minimum, but provide a variety of assets with similar themes to better understand your target audience. Unless you want to focus solely on Google Shopping, in which case read about PMax feed-only strategy.

Make sure your assets are relevant 

Ensure that each asset aligns perfectly with your campaign's objectives and target audience. A cohesive message across all assets will enhance the campaign's overall impact.

Choose only the best quality assets

High-quality assets are more likely to grab users' attention and encourage them to engage with your ad. Invest in professional visuals and well-crafted texts to make a lasting impression.

Include your own video asset

Include your own videos to have more control over branding, structure, and overall appearance. If you don't provide a video, Google will create one using the information you provided, but it will be more like a slideshow with system-selected music. It will probably not be very compelling.

Experiment with assets

Experiment with different asset variations to determine which combinations generate the best results. Google's machine learning algorithms can adapt and optimize based on the performance of each asset.

Regularly test new asset combinations and analyze their performance metrics. Continuous improvement and testing will lead to a more effective and efficient campaign over time.

Customize your assets for each Google platform

Keep in mind that your assets will appear on various Google platforms, such as Search, Display, YouTube, and Discover. Customize your assets to suit the format and context of each platform.
