Audience Targeting, explained properly.
What is audience targeting in Google Ads?
Audience targeting allows you to define who sees your ads based on who they are, what they are interested in, or what they have done, rather than solely what they are searching for. It adds precision on top of keyword targeting and proves valuable on the Display Network, YouTube, and Search as bid modifiers.
Types of audiences in Google Ads
- **Demographic audiences:** target by age, gender, parental status, or household income. - **Affinity audiences:** people with demonstrated long-term interests (for example, home improvement enthusiasts). - **In-market audiences:** people actively researching a product or service category right now, with high purchase intent. - **Remarketing audiences:** previous visitors to your website. - **Customer match:** upload your customer email list and target those people across Google. - **First-party data audiences:** audiences built from your own CRM, email list, or website data.
The main audience types
### 1. Custom audiences (custom segments) Defined by interests, URLs people have visited, apps they use, or specific keywords they have searched for recently. The most flexible audience type, useful for targeting people exhibiting specific commercial behaviour. ### 2. In-market audiences People Google has identified as actively researching products or services in a specific category. Strong commercial intent, especially valuable for ecommerce and lead-generation campaigns. ### 3. Affinity audiences People with long-term interests in broad topics (sports fans, foodies, technophiles). Best for brand and awareness campaigns; less commercially focused than in-market. ### 4. Demographic targeting Age, gender, parental status, household income (where data is available). Layer on top of other audience types rather than relying on it alone. ### 5. Customer match Upload your existing customer list (email, phone) and target ads to those specific people, or to lookalikes Google generates from them. Powerful for reactivation, retention, and similar-audience expansion. ### 6. Remarketing audiences People who have already interacted with your site, app, or YouTube channel. The highest-converting audience type for most accounts because they already know you.
Observation vs targeting
Audiences can be added in two modes: - **Observation:** your ads still show to everyone, but you collect data on how different audiences perform and can apply bid adjustments. - **Targeting:** your ads only show to users who match the audience segment. Targeting (sometimes called targeting and bidding) restricts the campaign to only people in that audience. Observation lets the campaign reach everyone but reports on how the audience performs separately. For most accounts, starting in Observation mode and switching specific audiences to Targeting once you see what performs is the safer approach.
Audience Targeting: common questions.
Is audience targeting better than keyword targeting?
They work together rather than competing. Search campaigns combine keywords (intent) with audience layers (who that person is). Display and YouTube campaigns rely more heavily on audience targeting because there is no search query. Both have their place; the strongest campaigns use both.
How big should an audience be?
Big enough that Google has data to optimise, small enough that it is meaningfully different from random users. For Search audience layers, no minimum applies. For Display and YouTube targeting, audiences below 5,000 users tend to deliver inconsistent results.
What is the difference between in-market and affinity audiences?
Affinity is long-term interest (sports fans, foodies, technophiles). In-market is short-term active research (people currently looking to buy a car, plan a holiday, hire an accountant). In-market is closer to commercial intent; affinity is closer to awareness.
Can I target competitors' customers?
Not directly, but indirectly through Custom Audiences. You can build a custom segment of people who have searched for your competitor's brand or visited their website, then target them. Effective when paired with messaging that addresses why someone might switch.

“I've had the pleasure of working with Chris on several SEO projects for my websites in the health field. He was definitely been able to demystify things so that I felt able to make decisions with him and feel confident they were the right ones. For a non-techie, that is worth gold! I look forward to working with Chris again and warmly recommend him to anyone who - like me - is unsure about all things SEO.”
