Display Ad Targeting Options on the Google Display Network (GDN) and YouTube
There are eight different ways to target ads running on the Google Display Network, or GDN. Each display ad targeting option is based on either the content or keywords of websites across the GDN, or the behavior of traffic that transits the GDN.
Display ad targeting matters because the Google Display Network can reach a broad audience. Without a clear targeting plan, a campaign can spend budget on impressions and clicks that do not match the business goal. A stronger targeting setup helps narrow the audience, test useful segments, and improve campaign performance over time.
YouTube as a Display Ad Placement
The Google Display Network extends beyond traditional websites to include YouTube, which means display campaigns can target YouTube channels, individual videos, and the broader YouTube platform as placements. This opens up a significant reach opportunity, since YouTube is among the most visited properties on the internet and draws audiences across virtually every interest category and demographic.
Within a display campaign, YouTube can be targeted through placement targeting by selecting specific channels or videos where ads should appear. Advertisers can also layer audience signals — such as in-market segments, affinity audiences, or remarketing lists — on top of YouTube placements to further refine who sees the ads. This combination of content context and audience intent makes YouTube placements a flexible option within a broader display strategy.
It is worth noting that YouTube also supports its own dedicated campaign type with formats, bidding strategies, and targeting logic specifically designed for video. Display campaigns can reach YouTube, but they operate differently than native YouTube campaigns, and the two approaches are not interchangeable.
Because YouTube advertising is a substantial topic on its own — covering video ad formats, campaign structure, targeting, and optimization — we cover it separately in our YouTube and video advertising section.
Display Ad Targeting Options on the Google Display Network (GDN)
To plan display ad targeting for a campaign, we first determine which of the eight types of targeting are likely to be successful. The main options are in-market, placement, affinity, custom intent by URL or keyword, customer list matching, topic, demographic, and remarketing. Compound, hybrid, and negative audiences further expand the flexibility of targeting.
Common Display Ad Targeting Options
- In-market audiences — These are users Google has identified as actively researching or comparing products and services in a specific category. Because they are further along in the buying process, in-market audiences often produce stronger conversion rates than broader targeting methods.
- Placement targeting — With placement targeting, ads are shown on specific websites, YouTube channels, or apps that the advertiser selects. This gives precise control over context and can be especially useful for brand alignment or reaching niche audiences clustered around specific content.
- Affinity audiences — Affinity segments group users based on long-term interests and lifestyle patterns. These audiences are better suited to brand awareness goals than direct response, since they reflect habitual interests rather than active purchase intent.
- Custom intent audiences — Custom intent allows advertisers to build an audience from specific keywords or URLs that people have recently searched or visited. This is a flexible option that sits between the broad reach of affinity and the purchase-ready signals of in-market.
- Customer list matching — By uploading a customer email list, advertisers can target known contacts directly or build similar audiences based on shared characteristics. Customer match is particularly useful for re-engagement campaigns or for reaching existing customers with new offers.
- Topic targeting — Topic targeting places ads across websites that are categorized under specific subjects, such as finance, health, or travel. It is a content-based approach that can complement audience-based methods by controlling where ads appear rather than who sees them.
- Demographic targeting — Demographic filters let advertisers restrict or prioritize delivery based on age, gender, parental status, or household income. These filters are most useful when there is a clear customer profile that maps to demographic categories.
- Remarketing audiences — Remarketing targets users who have previously visited a website, used an app, or interacted with content. Because these users already have some familiarity with the brand, remarketing often delivers stronger engagement and conversion rates than cold audience targeting.
Choosing the Best GDN Display Targeting Methods
Selecting the right mix of targeting options depends on the campaign goal, the stage of the funnel being addressed, and the available data. A brand awareness campaign may lean on affinity and topic targeting to generate broad reach, while a conversion-focused campaign is more likely to use in-market, remarketing, or customer list matching.
Compound and hybrid audiences combine multiple targeting methods to narrow or expand reach. For example, layering in-market signals on top of a topic-targeted placement can help ensure ads are shown in relevant contexts to users who are already showing purchase intent. Negative audiences work in the opposite direction, excluding segments that are unlikely to convert or that would be wasteful to reach — such as existing customers in a new acquisition campaign.
Understanding how each option interacts is part of building a targeting strategy that can be tested and improved over time. No single approach works for every campaign, and the right combination often depends on data that only emerges after the campaign has run.
Why Display Targeting Requires Testing
A significant degree of experimentation is normally required before arriving at the best-performing type and configuration of audiences for display campaigns. This is why display targeting should be reviewed as part of broader PPC campaign management, adaptive optimization, and PPC performance review.
Display campaigns often need experimentation because different audiences, placements, and targeting combinations can perform very differently depending on the industry, offer, and campaign goal. Testing helps identify which audiences produce useful engagement, conversions, or assisted conversions, and which segments should be excluded or reduced.
When reviewing display performance, it is important to look beyond click-through rate. Display campaigns often contribute to conversions that are attributed to other channels, and assisted conversion data can be as important as direct conversion data when evaluating audience quality. Placements should also be reviewed regularly, since the GDN includes a wide range of websites, and some may generate traffic that does not align with campaign goals even when audience targeting is otherwise well configured.
Iterating on audiences — testing one variable at a time, allowing enough data to accumulate before drawing conclusions, and applying learnings to future campaigns — is the foundation of effective display targeting over time.
Frequently Asked Questions
What is display ad targeting? Display ad targeting is the process of choosing which audiences, websites, topics, placements, or demographic groups may see display ads. It helps advertisers control where ads appear and who is most likely to see them.
What are the main Google Display Network targeting options? The main targeting options include in-market audiences, placement targeting, affinity audiences, custom intent audiences, customer list matching, topic targeting, demographic targeting, and remarketing audiences.
Why does display ad targeting need testing? Display ad targeting needs testing because audience behavior can vary by industry, offer, market, and campaign goal. Testing helps identify which targeting options are producing useful traffic, conversions, or assisted conversions.
What are negative audiences in display campaigns? Negative audiences are audience segments that are excluded from a campaign. They can help reduce wasted spend by preventing ads from serving to groups that are unlikely to convert or do not match the campaign goal.
