Case Study: Display Ads Media Strategy – Exceeding Industry Benchmarks for GDN Campaigns
Driving Leases with Strategic Display Advertising
Overview
At GTMA, we crafted a tailored media strategy for a client’s Google Display Network (GDN) campaign that delivered exceptional results, surpassing industry benchmarks. Through strategic audience segmentation and optimized ad formats, we achieved a 35% increase in lease sign-ups while cutting cost per acquisition (CPA) by 20%. Here’s a breakdown of how we made it happen.
Audience Segmentation: Targeted Strategies, Outstanding Results
Our approach to audience segmentation involved creating precise custom audiences and leveraging remarketing techniques. Each segment played a key role in boosting conversion rates and lowering CPA compared to industry norms.
Custom Audiences – Unmatched Performance
- Conversion Rate: 42% (52.5% above the industry benchmark of 0.8%)
- CPA: $20 (73% lower than the industry standard of $74.79)
- Why It Works: Custom audiences targeted users actively seeking apartments, resulting in significantly higher conversion rates and lower acquisition costs.
Remarketing Audiences – Effective Re-Engagement
- Conversion Rate: 30% (37.5% higher than industry standard)
- CPA: $30 (60% lower than industry standard)
- Why It Works: Remarketing re-engaged potential customers who had interacted with the client’s website, leading to impressive conversion improvements.
Interest-Based Audiences – Broadening Reach
- Conversion Rate: 18% (22.5% higher than the industry benchmark)
- CPA: $40 (46.5% lower than the industry average)
- Why It Works: This approach widened visibility while maintaining efficiency, though it had slightly higher CPAs compared to more targeted segments.
“Apartments for Rent” Audiences – Consistent Visibility
- Conversion Rate: 10% (12.5% above industry benchmarks)
- CPA: $60 (19.8% lower than average)
- Why It Works: This broader audience segment helped maintain visibility, though it was less cost-efficient compared to highly targeted approaches.
Ad Formats: Responsive Display Ads Deliver Superior Results
We utilized Responsive Display Ads (RDAs) to maximize the impact of our campaign, leading to a significant increase in conversions and a reduction in CPA when compared to standard display ads.
Responsive Display Ads (RDAs) – Top Performer
- Conversion Rate: 50% higher than standard display ads
- CPA: 20% lower than standard display ads
- Why It Works: RDAs automatically adjust their format for optimal performance, enhancing engagement and delivering industry-beating click-through rates (CTR) and cost-per-click (CPC).
Standard Display Ads – Lower Performer
- Conversion Rate: 33% lower than RDAs
- CPA: 15% higher than RDAs
- Why It Works: Lacking the adaptability of RDAs, standard ads were less efficient in driving conversions and incurred higher costs.


Results Summary & Strategic Recommendations:
- Top Audience Segments: Allocate 70% of your ad spend to custom and remarketing audiences, which achieved conversion rates up to 52.5% higher and CPAs up to 73% lower than industry standards.
- Optimal Ad Format: Invest 80% of your display ad budget in Responsive Display Ads (RDAs) for a 50% higher conversion rate and 20% lower CPA compared to standard display ads.
- Broader Reach: Use interest-based audiences and broad search terms like “Apartments for Rent” to expand visibility, but limit budget allocation to ensure cost efficiency.
