Google Ads audience targeting is one of the most powerful tools in your digital marketing arsenal. Get it right, and you’ll reach the right people at the right time with the right message. Get it wrong, and you’ll be throwing money at ads that no one cares about.

If you’re running an eCommerce business and looking to maximise your ad spend, this guide will walk you through everything you need to know about Google Ads audience targeting. We’ll also cover essential strategies like keyword strategy, ad copy and creatives, bidding strategy, and why you might want to consider a management service.

What is Google Ads Audience Targeting?

Google Ads audience targeting allows you to segment and focus on specific groups of people who are most likely to convert. Instead of showing your ads to a broad, uninterested audience, you can narrow it down based on factors like demographics, interests, and past behaviour.

Why Audience Targeting Matters

  • Reduces wasted ad spend by focusing on potential buyers
  • Improves conversion rates by reaching people with relevant interests
  • Helps tailor ad copy and creatives to the right audience
  • Increases return on investment (ROI) by optimising engagement

Types of Google Ads Audience Targeting

Google offers several ways to target your audience. The key is understanding how each works and choosing the right mix for your business.

1. Demographic Targeting

You can target users based on:

  • Age
  • Gender
  • Household income
  • Parental status

For example, if you sell high-end baby products, you’d likely want to target parents within a certain income range.

2. Affinity Audiences

These are people who have demonstrated a long-term interest in a topic. If you sell fitness equipment, targeting the “Health & Fitness Enthusiasts” affinity audience could work wonders.

3. In-Market Audiences

These users are actively researching or considering purchasing a product like yours. Google determines this based on search behaviour and browsing activity.

4. Custom Audiences

Create your own audience segments based on:

  • Specific keywords people search for
  • Websites they visit
  • Apps they use

If you run an eCommerce store selling eco-friendly products, you can create a custom audience targeting people who’ve searched for terms like “sustainable home goods.”

5. Remarketing Audiences

These are people who’ve interacted with your website or ads before but haven’t converted yet. You can show them tailored ads to bring them back.

6. Customer Match

Upload a list of emails or phone numbers from your existing customers and target them directly on Google Ads. This is great for re-engagement and upselling.

7. Similar Audiences

Google finds users similar to your existing customers and targets them with your ads. This is an excellent way to scale your campaigns.

How to Build a Winning Google Ads Audience Targeting Strategy

Now that you know the different types of targeting, here’s how to apply them effectively.

1. Define Your Ideal Customer

Start by answering these questions:

  • Who is your target audience?
  • What problems are they trying to solve?
  • What products or services are they looking for?
  • What websites do they visit?
  • What search terms do they use?

2. Combine Audience Targeting with a Strong Keyword Strategy

Your audience targeting should align with your keyword strategy. If you’re running search ads, ensure your keywords match what your ideal customers are searching for.

For example:

  • If you sell custom T-shirts, target keywords like “custom printed T-shirts” and “personalised T-shirts online.”
  • Use custom intent audiences to target users who’ve searched for these terms recently.

3. Optimise Your Ad Copy and Creatives

Your ads should speak directly to your target audience’s needs.

  • Use engaging ad copy and creatives that address their pain points.
  • Highlight your unique selling points (e.g., “Fastest Shipping” or “100% Organic Ingredients”).
  • Include strong calls to action like “Shop Now” or “Get 10% Off Today.”

4. Test and Adjust Your Bidding Strategy

Your bidding strategy determines how much you’re willing to pay for each ad placement. To optimise your budget:

  • Start with manual bidding to control costs.
  • Test automated strategies like Target ROAS (Return on Ad Spend) for better efficiency.
  • Adjust bids based on audience performance.

5. Leverage a Google Ads Management Service

If managing all of this sounds overwhelming, consider using a management service. An expert can:

  • Fine-tune your audience targeting
  • Optimise your ad spend
  • Improve your ad copy and creatives
  • Continuously test and refine your strategy

Common Mistakes to Avoid

  • Targeting too broadly – You’ll waste money on people who aren’t interested.
  • Ignoring audience insights – Use Google Analytics and Ads reports to refine your targeting.
  • Not testing different audiences – Run A/B tests to see which groups perform best.
  • Forgetting negative audiences – Exclude people who aren’t a good fit (e.g., competitors, existing customers who already converted).

Final Thoughts

Google Ads audience targeting can make or break your advertising success. By using the right mix of targeting options, refining your keyword strategy, ad copy and creatives, bidding strategy, and even considering a management service, you’ll get better results and spend your budget wisely.

Start small, test different audiences, and keep optimising. The more you refine your approach, the better your conversions will be.

Frequently Asked Questions

  • How do I know which Google Ads audience targeting option is best for me?

    It depends on your business goals. If you want brand awareness, affinity audiences work well. If you’re focused on conversions, in-market and custom intent audiences are better.

  • Can I use multiple audience targeting options at once?

    Yes! Combining multiple targeting methods often leads to better results.

  • How can I tell if my audience targeting is working?

    Check your Google Ads reports for metrics like CTR (click-through rate), conversion rate, and cost per acquisition (CPA). If they’re improving, your targeting is working.

  • Should I use automated or manual bidding for audience targeting?

    If you’re just starting, manual bidding gives you more control. As you collect data, you can switch to automated bidding strategies for efficiency.

  • What’s the best way to retarget past website visitors?

    Use remarketing audiences and show them tailored ads based on their past interactions with your site.
