When B2B marketers evaluate LinkedIn advertising, they want proof. Not theories about targeting or promises about lead quality—they want real results from real companies.
This guide compiles verified LinkedIn advertising case studies from 2025-2026, organized by company type and use case. Each example includes specific metrics, strategies employed, and lessons you can apply to your own campaigns.
LinkedIn advertising costs more than other social platforms. According to 2026 benchmark data, companies spending on LinkedIn ABM campaigns see median ROAS of 1.65x, with strong performers achieving 2.5-3.0x or higher.
But the real story isn't just ROAS—it's pipeline quality. Industry research shows LinkedIn drives 20-30% MQL-to-SQL conversion rates, compared to 8-15% for Meta Ads. Higher costs translate to higher-quality opportunities.
The case studies below demonstrate what's possible when LinkedIn advertising is executed strategically.

| Factor | Best Practice |
|---|---|
| Targeting | Narrow focus: 25-100 accounts for ABM |
| Creative | Real people > stock photos; authentic > polished |
| Formats | Prioritize Thought Leader Ads and Document Ads |
| Measurement | Track pipeline and revenue, not just leads |
| Timeline | Allow 90+ days for optimization |

| Metric | Average | Good | Excellent |
|---|---|---|---|
| ROAS | 1.5-2x | 2-3x | 4x+ |
| CPL | $100-150 | $75-100 | <$75 |
| MQL-to-SQL | 15-20% | 20-25% | 25-30% |

Based on 2026 case studies, expect 1.5-3x ROAS for well-managed campaigns, with top performers achieving 4-9x. The key differentiator is targeting quality—focused ABM campaigns significantly outperform broad targeting. Allow 90-120 days for optimization before evaluating ROI.
Case studies show meaningful results starting at $2,700/month for SMBs, with enterprise campaigns investing $15,000-$180,000/month. The minimum viable test budget is typically $5,000-$10,000 over 90 days. Higher budgets accelerate learning but aren't required for success.
According to 2026 benchmarks, Thought Leader Ads deliver the best CPC ($3.06 vs. $13.23 for image ads), while Document Ads achieve the highest lead form completion rates (22.73%). Video ads often underperform despite receiving significant budget allocation.
