Leveraging Audience Segmentation in Google Ads for Better Targeting

In advertising, simply choosing the right keywords and writing compelling ad copy isn’t enough. If you want to maximise the return on your Google Ads campaigns, you need to ensure your ads are reaching the right people — the ones most likely to convert. That’s where audience segmentation comes into play.

Google Ads offers powerful audience targeting features that allow you to deliver your message to specific groups of users based on their behaviours, interests, demographics, and intent. When used effectively, audience segmentation can significantly improve your ad relevance, click-through rates, and ultimately, your conversion rate.

Here, we’ll explore what audience segmentation is, the different types available, and how to use them strategically to enhance your PPC performance.

What Are Audience Segments in Google Ads?

Audience segments are groups of people who share specific characteristics or behaviours that make them more likely to respond positively to your ads. Instead of blindly targeting everyone searching for your keywords, audience segments allow you to layer targeting based on who the person is, not just what they’re searching for.

For example, two users might both search for “running shoes,” but one is a 25-year-old avid marathoner while the other is a 55-year-old looking for casual footwear. Their intent — and likely conversion behaviour — could be drastically different. Audience segments help you recognise and respond to these differences.

Why Audience Targeting Matters

Audience targeting improves both efficiency and effectiveness. Here’s why:

• Higher Relevance: Ads tailored to a specific audience are more likely to resonate, increasing click-through and engagement rates.
• Better ROI: You avoid wasting ad spend on low-quality clicks by focusing on users more likely to convert.
• Smarter Bidding: Google can use machine learning more effectively when audience data is included, enhancing automated bidding strategies.
• Improved Personalisation: You can tailor your messaging, offers, and landing pages based on who you’re targeting.

Types of Audience Segments in Google Ads

Google Ads provides a variety of built-in audience categories as well as options to create custom segments. Let’s break them down.

Affinity Audiences

These are broad groups based on long-term interests, lifestyles, and habits. Ideal for brand awareness campaigns, affinity audiences include categories like “Health & Fitness Enthusiasts” or “Tech Savvy.”

In-Market Audiences

These users are actively researching or comparing products/services and are more likely to make a purchase soon. For example, someone in the “In-Market for Home Security Systems” category is likely shopping right now.

Demographic Segments

Target based on age, gender, parental status, and household income. While broad, layering demographic data can help refine your ideal customer persona.

Life Events

Target users who are going through major life changes like getting married, graduating college, or moving. These can be powerful triggers for certain purchases (e.g., furniture for recent movers).

Custom Segments

Formerly known as custom intent and custom affinity audiences, custom segments allow you to define your own audience based on:

• Keywords users have searched
• URLs they’ve visited
• Apps they use

You can tailor these audiences tightly to align with niche products or services.

Remarketing Lists

Remarketing (or retargeting) allows you to re-engage users who have already interacted with your website, app, or YouTube channel. These are high-intent users who are already familiar with your brand.

Customer Match

This feature lets you upload your own customer data (such as email lists) and target users across Google properties. Perfect for loyalty campaigns or upselling existing customers.

How to Use Audience Segments Strategically

To get the most out of audience targeting in Google Ads, you need a clear strategy. Here are some key tactics:

Layer Audiences with Keywords

Don’t choose between audience or keyword targeting — combine them. Layering audiences on top of keyword targeting ensures that your ads show only to users who are both interested in your offer and actively searching for related terms.

Adjust Bids Based on Audience Performance

You can set bid adjustments at the audience level. If a certain audience is converting at a higher rate, increase your bid to show more often to those users. Likewise, decrease bids for underperforming segments.

Use Audience Observations

Not sure which audiences will perform best? Start with observation mode instead of targeting mode. This lets you collect data on different segments without limiting your reach, helping you discover high-performing audiences over time.

Tailor Ad Copy and Creative

You can create different ads or even landing pages for different audiences. For instance, you might highlight convenience for busy professionals and affordability for budget-conscious shoppers.

Exclude Irrelevant Audiences

Audience targeting isn’t just about inclusion — it’s also about exclusion. If certain demographics, locations, or interests don’t align with your product, exclude them to avoid wasted spend.

Final Thoughts

Audience segmentation is one of the most underutilised — yet most powerful — tools in Google Ads. By leveraging these segments strategically, you can refine your targeting, reduce wasted spend, and boost your campaign performance across the board.

Whether you’re just starting or looking to scale a mature campaign, don’t underestimate the value of aligning your ads not just with what people are searching for, but with who they are and what they care about.
