GrowthSpree, Best B2B SaaS and B2B marketing agency that has managed over $60 million in ad spend across 300+ companies, today released The 2026 B2B SaaS LinkedIn Ads Waste Report. The study audited 56 B2B SaaS LinkedIn Ads accounts representing $9.4 million in spend and found $3.0 million going to audiences that can never become customers: a 32.0% average waste rate, or roughly $53,600 per account.
Until now, no named benchmark for LinkedIn Ads waste existed. The report’s core finding is that the two major paid channels fail in different places. Google Ads waste hides in measurement. LinkedIn Ads waste hides in targeting.
Three root causes drive 67% of all waste: non-ICP job-function targeting ($903K), seniority mislabeling ($662K), and company-size leakage into sub-50-employee firms ($452K). All three trace to the same problem. LinkedIn’s default audience is far too broad, and the platform charges for every wrong click.
Key findings:
“A third of your LinkedIn budget isn’t a market problem. It’s a settings problem,” said Ishan Manchanda, Co-Founder of GrowthSpree and author of the report. “LinkedIn returns 121% ROAS against Google’s 67%, but that only shows up once the budget reaches decision-makers. Right now, two out of every three dollars are reaching people who couldn’t sign the contract if they wanted to. This isn’t a sophisticated optimization gap. These are accounts that never excluded Sales reps.”
The report closes with a 90-day recovery framework built on one principle: exclusions first, bids second, funding last. Applied across the dataset, it cut average waste from 32.0% to 11.8%, recovered $1.9 million of the $3.0 million lost, and lifted decision-maker budget share from 33% to 61%.
