Case Study: Nextdoor achieves 3X ROI and 25% lower CPA with LinkedIn Marketing Solutions

How Round Barn Labs Helped Nextdoor Achieve Stellar ROI on LinkedIn

Nextdoor, the private social network for neighborhoods, partnered with growth agency Round Barn Labs to grow awareness of its real estate agent sponsorship product. The team was tasked with increasing agent acquisitions by 50% while cutting advertising costs by 10%, so they sought a channel with deep audience insights and strong ROI to reach that professional audience.

Round Barn Labs launched LinkedIn Ads using Job Title and Job Interest targeting, retargeting, and frequent A/B creative tests to raise CTR and conversion rates. The campaign lowered costs and exceeded goals — delivering a 3× return on investment and a 25% reduction in cost per acquisition — while enabling bidding and creative optimizations that improved overall efficiency.
