Case Study: Blenders Eyewear achieves profitable Instagram ad campaigns and 42M+ reach with Buffer

How Blenders Eyewear Creates Profitable Instagram Ad Campaigns

Blenders Eyewear, a San Diego-based sunglasses brand known for bold visuals and a network of content creators, faced the challenge of turning Instagram’s organic momentum into provable, scalable ad performance. The team needed to maintain a compelling feed while demonstrating measurable ROI to justify and grow ad spend.

They solved this by mirroring high-performing organic content in ads, front‑loading captions, using native-looking Stories for time‑sensitive promos, and focusing on ROAS as the primary metric. The approach reached over 42 million people, with Instagram delivering about 25% of ad spend and ROAS ~15% higher than Facebook (CPCs 60% lower, CPMs 50% lower, CTR 33% higher), enabling continued and increased investment in Instagram ads.
