Microsoft Performance Max: Specs, Setup, & Conversion Tips

Since their introduction, Google’s Performance Max campaigns have succeeded in both amplifying ad engagement and streamlining workflows for marketers across the board.

Aiming to replicate Google’s success for the Microsoft network, Microsoft recently announced their own version of Performance Max campaigns. The beta launched on July 5th 2023, and is was rolled out globally on 5th March 2024.

Microsoft hasn’t exactly been creative here, using the same name as Google for their Performance Max campaigns. Microsoft’s version of Performance Max comes a full three years after Google’s Performance Max was first made available in beta.

Marketers aiming to make the most out of their ad spend will need to understand the key differences between the Google and Microsoft versions of Performance Max, and optimize their campaigns for each platform.

Here, we’ll walk you through everything you need to know about Microsoft Performance Max, including: 

• The basics of Microsoft Performance Max
• How Microsoft Performance Max compares with Google Performance Max
• How to set up a Microsoft PMax campaign

What is Microsoft Performance Max? 

According to Microsoft, “Performance Max is an asset-focused campaign type that allows you to easily create and manage your campaigns, optimize ads to reach the right audience at the right time, and drive performance to meet advertising goals—across the entire Microsoft Advertising Network. Rather than manually creating ads one by one, you can save time by adding assets, such as text and images, to your asset groups and let us take care of the rest.”

The primary goal of Microsoft Performance Max campaigns are to find and convert more customers across the entire Microsoft network. It does so by pairing the right creative assets with the right targeting parameters in real time.

Performance Max campaigns use Microsoft AI to optimize and manage ads across various channels and formats within the Microsoft Advertising Network.

When Should You Use Microsoft Performance Max?

According to Microsoft’s documentation, Microsoft PMax is the best option to use when you want to:

• Meet specific performance goals, such as increasing sales and driving potential customers to your website. Do so by leveraging machine learning and AI to optimize ad delivery across channels.
• Enhance your return on ad spend and maximize reach across the entire Microsoft Advertising Network. PMax helps utilize audience targeting to deliver ads to the most relevant audiences at the right time across different platforms.
• Display your ads across the entire Microsoft Advertising Network with a single campaign. When you run a PMax campaign, Microsoft shows your ads across all channels – Bing, Yahoo, and Microsoft Audience Network partner sites.
• Expand your ad reach and increase conversion value by serving search, audience, and product ads.

Key Benefits of Microsoft Performance Max 

There are four key benefits of Microsoft PMax:

1. Run Ads Across All Microsoft Channels

The best part about Microsoft PMax campaigns is that you can run ads across the entire Microsoft Network from a single campaign. This is perfect for businesses with small ad budgets who don’t have an in-house team to set up every individual channel for their ad campaigns.

2. Save Time

Performance Max campaigns save marketers time by allowing them to create a single campaign that targets multiple ads and channels, streamlining the workflow for marketers.. 

Those who use PMax campaigns won’t have to manage multiple ad campaigns simultaneously. Instead, promote products via a singular campaign, and PMax’s automation serves your creatives to the right audience, on the right platform, at the right time.

3. Use AI and Automation to Maximize ROAS

Performance Max campaigns leverage AI and automation to keep up with customer trends, selecting the best possible asset combination for your ads. The AI updates these ads in real time to boost conversion value and achieve campaign objectives.

4. Complement Search Campaigns

Performance Max is designed to complement your keyword-based search campaigns. It helps you find more converting customers across all of Microsoft’s channels rather than relying solely on a keyword-based approach.

This can futureproof your campaigns as Microsoft follows Google on the move towards a keywordless future.

How to Set Up a Microsoft Performance Max Campaign

Before setting up a Microsoft Performance Max campaign, you must  set up conversion tracking.

“Since Performance Max relies heavily on automation, it needs conversion signals to have any chance to improve ad performance with automation.” – Joe Martinez

After you have the conversion tracking set up, follow the steps below:

Step 1. Create a New Campaign

Click the ‘+Create’ button on your Microsoft campaign viewer to start a new campaign.

Step 2. Select Campaign Objective

There are a variety of campaign objectives to choose from, but remember – Performance Max isn’t available for all objectives.

For example, video views won’t give you an option to run a Performance Max campaign, whereas campaign objectives like Selling products from your catalog will have Performance Max. 

For this example, we are going to select the Visit to My Website objective as it has performance max enabled.

Choose Performance Max and click ‘Next.’

The maximum number of pictures you can incorporate into a single ad campaign is 20. But, when uploading then, remember these two things:

1. Upload at least one image with a resolution – 1.91:1
2. Upload at least one image with a 1:1 aspect ratio

Finally, always opt for high-resolution images in .JPG or .PNG format, and before uploading, ensure your images adhere to all guidelines.

First, go ahead and paste the URL you want ad viewers to land on.

Add images according to the specifications and requirements we talked about earlier. As you add images, you can see how your ad will look in the preview window on the right-hand side.

Now for the main part – your ad copy:

Step 5. Adding Audience Signals

“Although setting up audience signals part is optional, I highly recommend you give Microsoft some signals of who you actually want to reach.” – Joe Martinez.

Either create a new audience signal or browse from existing options.

Let’s first see how to create a new one.Click ‘Create.’

Name your audience signal.

The Interests tab lets you add Microsoft in-market audiences to your asset group. 

Add the audience you want to target and save it by clicking the Save button.

As this is a remarketing campaign, we will use first-party data to retarget people who previously interacted with my website. 

Next, go to ‘Your first-part data.’ Click the ‘+ Add audience list.’

This option will let you choose from any existing audience you have created within Microsoft ads.

The last section is Demographics, where you can choose the range of ages and genders you want to target.

Once everything is finalized, click Save.

Choose the start and end date, and click Save to save your asset group.

Note: After your ad has been reviewed and approved by Microsoft, you’ll still have to wait a while for your campaign to go live. That’s because Performance Max campaigns have a learning phase – It could take up to two weeks for your PMax campaign to run optimized ads.

Step 6. Adding Extensions

From the left side menu, click the Extensions option.

Click ‘View: Sitelink Extension’ and select the Sitelink from the existing ones.
