Quick answer: The Google Display Network (GDN) is Google’s network of partner websites, apps, and YouTube channels where image, banner, and video ads can run. Unlike Search ads (text-only, triggered by keywords), Display ads are visual and reach users while they’re browsing other content. GDN is best for awareness, retargeting, and reaching audiences with specific interests.
What Is the Google Display Network?
The Google Display Network (GDN) is a collection of over two million websites, apps, and Google-owned properties (including YouTube and Gmail) where Google can serve visual advertisements. It reaches an estimated 90% of internet users worldwide.
Display Network advertising is fundamentally different from Search advertising. On Search, you reach people actively looking for what you offer. On Display, you reach people while they are doing something else, and interrupt their attention.
Display vs Search, Intent Difference
- Search: Pull marketing, users come to you by searching
- Display: Push marketing, you show your ad to users who are not actively searching for you
This means Display typically has lower click-through rates (0.1 to 0.5%) and lower direct conversion intent. It works best for brand awareness, remarketing, and keeping your brand visible to warm audiences.
Avoiding Display Waste
Without careful placement management, Display campaigns can show on irrelevant, low-quality sites. Regularly review the Placements report and exclude sites that do not deliver results.
Display is used selectively in our PPC campaigns, mainly for remarketing rather than cold prospecting.
What the Display Network Includes
- Over 2 million websites in the AdSense and Ad Exchange networks.
- YouTube (banner ads on videos, plus dedicated video ad formats).
- Google-owned properties: Gmail, Discover feed, Google News.
- Mobile apps in the AdMob network.
When Display Works Well
- Retargeting: showing ads to users who already visited your site. Highest-converting display use case.
- Awareness: building brand recognition before users search for you directly.
- Audience targeting: reaching people based on interests, demographics, or in-market signals when search volume is too low.
- Visual brands: products and services where seeing is half the sell.
When Display Underdelivers
- When used as direct-response without clear targeting (often produces lots of clicks at very low conversion rates).
- When creative is generic or text-only.
- When budget is too small for the audience size (display needs scale to find the right people).
- When attribution is set to last-click (display assists more than it directly converts).
Frequently Asked Questions
Should I run Display campaigns alongside Search?
Often yes, with different goals. Search captures demand from people actively looking. Display creates demand and reaches people earlier in the journey. Most accounts benefit from both, with Display getting a smaller budget share than Search and being measured differently (assisted conversions, view-through, brand search lift).
Why are my Display CTRs so low?
Display CTRs typically run 0.05% to 0.5%, much lower than Search’s 2-10%. That’s normal: Display ads interrupt browsing rather than answering active search. Don’t compare Display CTR to Search CTR. Compare to other display benchmarks: under 0.1% is weak; 0.5%+ is strong.
How do I prevent Display from wasting budget?
Three controls. Tight audience targeting (don’t leave it on broad keyword targeting). Placement exclusions (block obvious low-quality placements like mobile games, made-for-ads sites). Conversion-focused bidding (Maximise Conversions or Target CPA, not Maximise Clicks). Without these, Display campaigns can rack up clicks that don’t convert.
Is Display the same as Performance Max?
No. Display Network is one channel; Performance Max is a multi-channel campaign type that includes Display alongside Search, YouTube, Gmail, and Discover. For pure display campaigns, standalone Display campaigns give more control. Performance Max trades control for cross-channel reach.
Take this further
Display campaigns work when the targeting is tight and the goal is clear. Most failed Display campaigns failed because they were treated as Search campaigns rather than as their own discipline.
