Audience segments are groups of users that Google segments based on their interests, behaviors, demographics, and online activities. Think of it as ready-made customer profiles that help you reach the right people at the right time.

Why segment your audience in the first place? The answer is simple. Relevance drives results. When your ads are relevant to the needs and desires of your target audience, you’ll likely see a significant boost in key metrics.
- Increased user engagement – running ads for the audience with specific interests is more likely to convert.

Google Audience segments can be categorized into three main groups such as Audience segments, Your data segment, and Custom segments.

In this blog, we will look at audience segments in detail. In this category, there are different subgroups, such as Affinity segments, In-Market segments, Life events, and Detailed demographics.
How to access various audience segments in Google Ads?
To access audience segments in Google Ads, navigate to the audiences section by clicking on the Campaigns icon and then selecting Audiences. From there, you can view and manage different segments in the Audience Segments. Let’s explore each segment in detail.
Types of Audience Segments
1. Affinity Audience Segments

When you click on affinity audience segments, you will be able to see the following filters based on audience actively researching or planning.
Affinity segments are a way to reach users based on their passions, habits, and interests. It is beneficial to approach shoppers’ fundamentals and lifestyles. It is necessary if you want to connect with shoppers on an emotional level based on their interests.
With the affinity segments, you can target the audience based on their interest, such as sports, fitness, tech enthusiasts, lifestyle, hobbies, green living, etc.
For example, a retailer selling yoga mats could target audiences such as sports & fitness, health & fitness, or yoga lovers. These are the target users who are consistently interested in yoga and related products.
2. In-Market Audience Segments

Wouldn’t it be powerful to reach people who are actively researching or considering purchasing products or services right now? Google identifies these users based on their recent browsing behavior and search queries, indicating a strong purchase intent. This makes in-market segments valuable for campaigns focused on conversions.
For example, a furniture retailer promoting new office chairs could target the business & industrial or office furniture in-market segment. This reaches individuals or businesses currently looking to purchase office furniture.
3. Life Events Audience Segments

Life events are a part of the in-market segment when users are at something important in achieving life milestones, such as getting married, moving homes, graduating from college, or starting a new job. This ensures your ads are timely and highly relevant to your audience.
For example, if you sell mattresses. Your marketing had to be sharp and cost-effective to succeed, so in the audience segments, you would choose the life events segment and target “recent movers” consumers. This is when you can witness a lift in purchase intent.
Note: The life events segment can only be run on YouTube and Display ads campaigns.
4. Detail Demographics Audience Segments

It lets you refine your audience based on long-term life facts such as age, gender, and household income. Detailed demographics can be set to narrow targeting.
Note: In the UK and European countries, you are not allowed to target based on sensitive household income data.
Let’s understand with an example, imagine you are creating a Google Ads campaign to promote a new line of durable and stylish denim jeans specifically designed for men.
Here are some specific, detailed demographic options you might consider selecting for your male denim jeans campaign, along with the rationale based on our previous discussion
[Gender: Male] This is the most fundamental selection to ensure you are primarily reaching men.
[Age] You might select specific age ranges relevant to your target market.
[Household Income] Select a target audience with specific household income.
For example, if your jeans are trendy and attract younger adults, you might choose 18 to 24 and 25 to 34. Using detailed demographics in this way allows you to refine your targeting and optimize your ad spend over time.
For your online store, using customer niche segments, especially through convenient tools like Simprosys Customer Match List, can significantly improve the effectiveness of your advertising by reaching highly relevant audiences.
When should you not use audience segments?
- When launching a new product or entering a new market, a broad approach is beneficial. If you run your ads without narrowing down to audience segments, it helps to establish initial brand recognition without excluding potential early adopters.
- For time-sensitive promotions. If you are running a flash sale or a time-sensitive promotion intended for a wide audience, narrow audience segments might restrict your promotional reach. A broader ad campaign ensures the promotion reaches a larger audience quickly.
- If you’re running Google Ads for the first time and have limited information about your audience, inaccurate targeting can significantly limit your campaign’s reach.
