Types of Custom Audiences in Google Ads

Google Ads offers a variety of audience types, each tailored to help you meet specific campaign goals and refine your targeting. Knowing how and when to use these audiences can make all the difference in connecting with the right people at the right time. Let’s break down the options.

Custom Intent Audiences

Custom Intent Audiences are designed to target users who are actively searching online for products or services related to your business. You create these audiences by adding keywords, URLs, or app names that reflect the behavior of your ideal customer. These audiences are perfect for reaching people who are already showing intent to purchase. They work well for Display, Discovery (Gmail), and Video (YouTube) campaigns, but they don’t apply to Search or Shopping campaigns. This makes them especially useful for engaging potential customers while they browse relevant content or watch videos.

Custom Affinity Audiences

Custom Affinity Audiences focus on users' broader interests, hobbies, and lifestyles. These are ideal for campaigns aimed at building brand awareness. For example, a company selling running shoes could target interests like "marathon training" or "fitness enthusiasts" by selecting websites and apps related to training schedules, race events, or fitness tips. This approach helps introduce your brand to new audiences and attract them into your marketing funnel.

Customer Match Audiences

Customer Match Audiences let you retarget people who already have a relationship with your business. By uploading your customer data - like email addresses, phone numbers, or user IDs - you can show tailored ads to existing customers or leads. This strategy is great for encouraging repeat purchases or for using Google’s machine learning to find new, high-intent users who share similarities with your current customers. It’s an effective way to leverage your first-party data for both retention and acquisition.

In-Market Audiences

In-Market Audiences are all about reaching users who are actively researching products or services and are close to making a purchase. For instance, if someone is comparing features of health products online, you can target them with ads that align with their search activity. This audience type is especially effective for driving conversions because it focuses on users at the bottom of the sales funnel. Google’s machine learning identifies these high-intent users based on their recent online behavior, ensuring your ads reach those ready to buy.

How to Create Custom Audiences Step-by-Step

Now that we’ve covered the basics of audience types, let’s dive into the step-by-step process for creating custom audiences in Google Ads.

Access Audience Manager

Start by heading to the Audience Manager, which serves as the control center for managing your audience segments. To get there, click on the "Tools" icon in your Google Ads account, navigate to the "Shared Library" section, and select "Audience Manager". Alternatively, you can access it through the "Campaigns" tab by opening the "Audiences, keywords and content" section and selecting "Audiences".

Once inside, you’ll find several sections, including "Your data segments," "Audiences," "Custom segments," "Combined segments," "Your data insights," and "Settings". These tools give you everything you need to fine-tune your targeting strategy.

Next, move on to setting up your audience parameters.

Set Audience Parameters

This is where you define exactly who your ads will target. Taking the time to carefully set these parameters ensures your campaigns reach the right people.

When creating custom segments, you’ll use three key criteria: keywords, URLs, and apps. Think about the words your ideal customers search for, the websites they frequent, and the apps they use regularly.

  • For keywords, aim for smaller, focused lists rather than large, general ones. If you’re targeting users further down the buying funnel, prioritize long-tail keywords and phrases that reflect clear intent to purchase. On the other hand, short-tail keywords are more effective for broad awareness campaigns.
  • For example, a coffee shop owner could target users who frequent nearby gyms or bookstores.

While building your keyword list, use the volume indicator to ensure your targeting isn’t too broad or too narrow. Also, think about how your ad copy aligns with the keywords and what should trigger your ad.

Save and Apply Custom Audiences

Once your audience parameters are set, it’s time to save and put them to work in your campaigns.

Give each audience a clear, descriptive name to make it easy to identify later. A good naming system can help you differentiate between interest-based and search-based audiences. For instance, you might label one audience "searched for [keyword]" and another "interest [keyword]".

Click "Create" or "Save" to finalize your custom audience. After saving, navigate to your campaign settings and select the "Audiences" section. From there, choose "Select an audience" and pick your newly created custom audience.

If you’re running campaigns across multiple platforms like video, discovery, or Gmail, consider creating separate lists. For example, one list could target users with general interests, while another focuses on those searching for specific terms. This segmentation allows you to fine-tune your targeting and improve campaign performance.

Custom audiences give you the flexibility to duplicate keywords across lists and rename them to create smaller, more targeted groups. This approach not only helps you pinpoint what drives conversions but also gives you greater control over your ad spend.

Finally, monitor and adjust your audiences regularly using Google Ads data to keep your campaigns optimized.

Best Practices for Custom Audiences

Once you've set up your custom audiences, the next step is to fine-tune them for optimal performance. Here are some proven strategies to help you get the most out of your campaigns.

Use Relevant and Specific Keywords

Choosing the right keywords is critical. Focus on terms that are relevant, have high search volume, and align with what your audience is actually searching for. Dive into your data to uncover the specific search terms your audience uses. This ensures your keyword strategy is based on real user behavior, not guesswork.

Tools like Google Ads Keyword Planner can be a great resource. By entering related words or your website URL, you can discover new keyword ideas. Aim for a balanced mix of short-tail and long-tail keywords. While short-tail terms can broaden your reach, long-tail phrases often attract users with clear purchase intent. Don’t forget to exclude irrelevant keywords to improve the quality of your clicks.

Striking the right balance between high-volume and niche keywords is key. High-volume terms help you reach a broader audience, while more specific keywords target users who are closer to making a decision.

Combine Multiple Data Points

Keyword research is just the beginning. To refine your targeting, layer additional data points for even greater precision. Google Ads allows you to create custom segments using relationships like AND, OR, or NOT between audience groups. For example, if you sell mobile accessories, you could target users who’ve shown interest in multiple product categories - like phones, headsets, and chargers - by using the “Narrow your segment (AND)” option.

Layering audiences helps you focus on users with the highest potential value. Use observation layering to bid more aggressively on these high-value users without limiting your overall reach. Keep an eye on reach estimates, which show the potential impressions for your combined audience. This will help you avoid creating segments that are too narrow or overly broad.

Additionally, the "Exclude segments (NOT)" option can be a powerful tool. Use it to filter out underperforming audiences or those that aren’t relevant to specific campaigns.

Monitor and Update Regularly

Custom audiences are not a "set it and forget it" strategy. To maintain their effectiveness, you need to monitor and update them regularly. User behaviors and interests shift over time, so keeping your audience data fresh is essential.

Analyze performance data from Google Ads to see how different audiences engage with your campaigns. Use this information to refine your approach - add new high-performing segments, remove those that aren’t delivering results, or tweak bid adjustments to focus on the most valuable users.

Leverage tools like conversion tracking and attribution models to measure the impact of each audience on your campaign. This helps you allocate your budget more efficiently across your custom audiences. Regularly review your bid strategy to ensure you’re maximizing your return on investment.

Establish a schedule - monthly or quarterly, depending on your campaign size - to evaluate and refresh your custom audiences. This consistent approach keeps your campaigns efficient and sets the stage for more advanced PPC strategies in the future.
