What Are Audience Signals in Performance Max?
Performance Max audience signals are indicators that advertisers can give to manage and guide the campaign toward the intended target audience. To effectively assess the impact of these signals, it’s essential to delve into PMax reporting, which provides insights into key metrics and campaign performance.
Since Performance Max campaigns are automated and offer little control over where your ads are displayed, audience signals become the lighthouses guiding Google’s AI down the right path. Find out more about what a Performance Max campaign is in this blog. You can also explore how PMax search themes further influence targeting and help advertisers refine campaign performance.
Ads appear to different users based on previous performance, industry, assets, and other factors. Google has placed audience signals in Performance Max to allow people to guide Google as to which audiences they want to target.
Audience signals are applied only at the ad group level. Google’s machine learning models may take up to two weeks to process, integrate, and optimize newly added audience signals.
Utilizing accurate audience signals can greatly impact your campaign’s performance. It can bring in more clicks, increase engagement, and boost overall campaign performance.
Types of Audience Signals
- First-Party Data (e.g., customer lists, website visitors, remarketing audiences).
- Google’s Audience Segments (e.g., in-market, affinity audiences).
- Custom Audiences (e.g., based on keywords, URLs, apps).
- Demographics (age, gender, parental status, household income)
First-Party Data
First-party data i.e., “your” data allows you to utilize the data you’ve collected over time.
It is the best way to indicate to Google the type of audiences that you have previously targeted and the audiences that have already interacted with you. First-party data allows you to offer personalized customizations to Google like:
- Those who have visited your site
- Those who are high-value customers
- Remarketing Lists for people who have made a purchase or added products to their cart but left it
- Customer Match lists can be used to exclude or include users based on their email addresses and other data.
| Important: To ensure smooth usage of audience signals, follow these requirements: 1. The audience list should align with the campaign’s operating system. For example, an iOS campaign must use iOS device IDs. 2. Refresh audience lists at least once every 540 days to keep them effective. 3. Each list must contain at least 1,000 active and eligible users. |
Google’s Audience Segments
Google Audience Segments are groups of people that Google has perceived to have similar tastes, interests, and hobbies based on their online behavior. Under Google’s audience segments, you can find audiences like:
- In-market audiences: Audience lists generated based on users who have a higher intent to purchase particular products. Google separates these audiences in different categories and updates them based on user behaviour.
- Affinity Audiences: Affinity audience is the list of people that Google has compiled based on their strong interest in particular topics and thus are more likely to convert.
Custom Audiences
You can generate custom audiences for specific keywords or terms, URLs, and apps certain audiences download–it is the closest alternative to adding search terms to a performance max campaign. These custom audiences can help you target audiences that your competitors are targeting or audiences that are looking for similar products or services as yours.
| Bonus: Read what custom audiences are on this official Google page. |
Demographics
Demographics are an essential part of any audience-targeting strategy. Using demographic audiences, you can target users of specific age groups, genders, marital statuses, etc.
Depending on the industry and niche, advertisers can broaden their reach when looking for new customers using demographic data.
Using demographic data, you can target:
- Different Age groups
- Genders
- Household Income
- Location
How Do Audience Signals Work?

- Audience Signals can be added to asset groups. You can link multiple audience signals to a single asset group. These signals help Google identify the audiences you want to target.
- Audience signals direct Google towards the audiences that you want to target. It is imperative to note that these signals are just suggestions, not hard targets.
- Google might target audiences beyond those included in the audience lists.
- While audience signals can be added to different asset groups, performance max campaigns do not provide granular data for how well these signals have been utilized (there is a way to keep track of this, know how!).
- Consequently, it is hard to measure the impact that these signals have had on overall campaign performance.
- While Audience Signals in Performance Max are not direct targeting tools, these campaigns do optimize themselves over time. These audience signals are dynamic and help target users more effectively and can have a significant longer-term impact.
- Additionally, you can even employ audience signals for A/B split testing to optimize your audiences and your campaigns further. These tests and recorded results will further enhance Google’s targeting and can be incredibly beneficial in the long run. For more guidance, check out these Performance Max best practices.
Performance Max Audience Signals Examples
Let’s say that you run a store selling bikes for adults and children. You want to increase awareness about your store and choose to utilize a performance max campaign.
Over time, you begin to realize that the audiences being targeted need improvisation. Here’s what you can do to improve targeting:
- You can add an audience signal using the data you’ve gathered by running previous campaigns. You can even add a segment from Google analytics that provides the data for customers who have visited your website but left without making a conversion.
- Next, you could target audiences based on demographics. So you select the age range appropriate for a younger audience with assets focused on bikes for kids–i.e., you target parents (age 25-35) and those who are living in and around your city.
- Now, you wish to add an audience signal that targets more interest-based audiences, so you add affinity audiences to your target audience and look for people who have shown an interest in sports equipment or people who look for biking routes on Google Maps.
Taking these steps into consideration, once you launch the campaign, you will begin to notice higher engagement from different channels, increased clicks and a rise in traffic flow to your website.
This is how audience signals work and can be utilized to improve the performance of a campaign.

The Impact And Benefits Of Audience Signals On Campaign Performance
Audience signals can be a vital factor in contributing to precise targeting for performance max campaigns. Let delve deeper into how audience signals can be beneficial for campaign performance.
Enhance Targeting Accuracy
Audience Signals are equivalent to suggestions you give to Google’s AI to improve the audiences that your ads are appearing for. Performance Max offers automated targeting to simplify advertisers’ jobs.
Instead of manually adding the audiences that you wish to target for every single campaign, audience signals offer you the chance to refine an existing target audience.
Maximizing Ad Relevance and Engagement
Google has clearly stated that ads from your Pmax campaign will be shown to people it deems relevant even beyond your audience signals. But what you must know is that audience signals can become the guiding factors for leading Pmax in the right direction for most (if not all) of your audiences.
If the highly relevant ads are shown to the right audience, there are significantly higher chances of them engaging with your ads.
Over time, Google’s AI will adapt to user’s behavior and show more targeted ads for highly relevant audiences too.
Budget Allocation
One drawback of a performance max campaign (compared to other campaigns such as search, display, etc) is that there is an incredibly high chance of wasted ad potential. Adding audience signals to a performance max campaign can work as the guiding factors to reduce the chances of ads appearing for people who are not interested.
Additionally, one cannot even monitor exactly where their ads are being shown, which impacts our budget. Pmax campaigns are known to be costly, and this is the exact reason why.

Performance Max Audience Signals Best Practices
Here are a few tips to help you make better use of audience signals in performance max campaigns:
Focus on High-Intent Audiences
To start off, one of the best things you can do is target high-intent audiences with granular specificity. This will reduce the chances of wasted ad potential and provide Google with a clear picture of your primary audiences. This is especially useful when running Performance Max for store goals, where precision can significantly impact in-store visits or local conversions. For campaigns focusing on feed-only strategies, consider exploring PMax feed-only strategies.
Use First-Party Data for effectiveness
To ensure that you are fully using your audience signals, you can utilize first-party data (i.e., the data you’ve collected over time on your website) to support the specificity of the audience signal.
You can use data from customers who have converted on your website, returning customers, remarketing lists for search ads, leads that you can extract from other data, customers that you want to retarget, etc.
Begin with Specific Signals
It is important to remember that Google will target audiences beyond what you add in your audience signals. Thus, it is better to ensure that the audience signals you add are highly specific.
Over time, you can broaden your audience signal if the performance is satisfactory. You can further narrow your audience signal if you find the performance inadequate.
One Asset Group= One Audience Signal
On Google’s pmax campaign, you have the option to utilize all audience signals for a single asset group. Instead, use one highly specific audience signal for a single asset group.
Since Google only shows you which asset groups are performing well, this is an excellent strategy for determining which audience signals are working well for you.
Doing this allows for concise tracking and will provide you with granular data for future campaign planning.
Add Relevant Assets for Audiences
To run a pmax campaign, you must upload and create asset groups. While creating the campaign, you can only add a single asset group. But once the campaign has been created, you can add upto a 100 asset groups per campaign.
Try to create an asset group with a major focus on the audiences that it will be shown to. A focused theme centered around specific audience signals can highly impact ad performance and increase clicks and conversions. Matching your asset group content to Performance Max placements—such as YouTube, Search, Display, Gmail, and Discover—can also improve relevance and user engagement.
Combining Audience Signal Types-Demographic and interest based audiences
Using specific audiences for specific asset groups still stands true, it does not apply to demographic and interest-based audiences. Since demographics and interest-based audiences are extremely broad categories, it becomes a risk factor if used individually.
A better option would be to combine the two under a single asset group and utilize audiences with maximum specificity.
Opt for Continual Testing
Keep in mind that even if you apply all the aforementioned tips, it might take a significant amount of time for desired results to start showing. Performance Max campaigns utilize machine learning and AI which gradually optimize over time. Additionaly, audiences on different platforms might perform differently based on how they’re being shown the ads. You can check out different pmax ad examples for more information.
While it automatically improves the targeting and ad relevance, it is important that you keep track of different factors affecting your ad performance. Continually monitor and keep testing variations of audience signals to get the best outcomes.
