9 Best practices for Performance Max assets

While it is possible to create effective campaigns using standard assets, going the extra mile can help your campaign truly stand out. Here are our top 9 best practices for successful Performance Max assets that we collected while running advertising for our valued customers:

1. Use as many assets as possible

Best practices for Performance Max assets

While it is possible to run a Performance Max campaign without assets, it is highly recommended to include as many assets as possible when utilizing them. Having a larger pool of creatives allows the algorithm to have more options for placements and enables Google to effectively test for effectiveness. It is important to ensure that the assets you add are relevant to your campaign.

In essence, aim for more than just the minimum number of assets within your asset group. Select a variety of assets with a consistent theme to better align with the desires and objectives of your target audience. By following this approach, you will likely see positive outcomes and better campaign performance.

2. Add your own videos

Add your own videos

When creating your own video asset for a Performance Max campaign, you have more control over branding, structure, and appearance. If you don’t provide a video, Google will generate one using your information as a slideshow with system-selected music. Follow these principles for an effective video:

  • Grab attention in the first 3-5 seconds: Use this opportunity to introduce your brand and engage viewers before the ‘Skip ad’ button appears.
  • Appeal to your target audience: Include information that resonates with your intended audience, keeping them engaged while filtering out less interested viewers.
  • Showcase your product or service: Clearly demonstrate key features and benefits to show how your offering meets their needs or solves their problems.
  • End with a clear call-to-action: Conclude your video with a strong and concise call-to-action, guiding viewers to take the desired next steps.

3. Enhance text assets with dynamic values

Adding dynamic values to your text ads is a recommended practice. It allows you to anticipate your target audience’s search queries and provide specific information, increasing relevance. The benefits of using dynamic values in ads include:

  • Time savings: Instead of creating separate headlines for each group, you can fill in a template once and let the dynamic values automatically match with the relevant asset group, saving time.
  • Relevance: Displaying specific information in your ads makes them more relevant, setting you apart from competitors.
  • Improved results: By incorporating dynamic values, customers immediately grasp the context of your ad, leading to higher-quality clicks and increased conversion probability.

Try these tips to improve the quality of your Performance Max assets.

4. Add audio to your videos

Add audio to your videos

In YouTube, it is common for users to play videos as background sound while focusing on other activities. Therefore, if your video only contains background music, you miss the opportunity to capture the attention of the viewer/listener.

To make the most of this situation, consider incorporating a compelling voiceover in your video. By doing so, you engage both the active and passive viewers. This approach increases the likelihood of viewers taking action based on your video, rather than just providing a pleasant musical interlude.

By including a clear voiceover alongside the visuals, you effectively grab the attention of viewers and enhance the effectiveness of your video in driving desired outcomes.

Anticipate trends, developments, and promotions

Stay relevant to your target audience by anticipating trends and promotions. Create smart asset groups that align with popular products, after-season sales, or special holiday discounts. By advertising the right products at the right time, you increase the likelihood of purchases. Design asset groups for specific events like Black Friday or Christmas, ensuring ongoing relevance for potential buyers. Stay up-to-date and maximize your chances of attracting and converting your target audience.

6. Constantly keep testing

What may be effective today doesn’t guarantee the same results tomorrow. That’s why ongoing testing of your assets is crucial.

For instance, try adding different call-to-action to your assets and run them simultaneously to identify the most effective approach. Instead of testing everything at once, focus on A/B testing to compare specific variations. Once you determine a winner, move on to the next test to refine your design or asset further. Follow this recommended timeframe for conducting tests:

Constantly keep testing

7. Let the branding surface everywhere

The higher the recognition, the greater the chance of making a purchase.

Ensure your logo, colors, and typography are recognizable across texts, banners, and videos. Maintain a cohesive brand identity for optimal results.

8. Give careful thought to asset group structure

Give careful thought to asset group structure

The structure of your Performance Max assets determines their type and effectiveness. You can base it on the target audience, performance, categories, or brands. A deeper structure aligns better with search queries and customer preferences, reaching customers at different stages of the sales funnel. However, it requires time and effort. Learn how to set up the best PMax campaign structure for your organization in our article.

9. Select the right call-to-action

Select the right calls-to-action

The primary goal of ads is to prompt action. To effectively guide your audience, carefully consider your call-to-action. Clearly identify whether you want them to make a purchase, read more, or get inspired. This prevents leading them astray and ensures a focused and desired response.

Final words

In conclusion, Google Performance Max assets are a powerful tool for optimizing your advertising campaigns.
