Is influencer marketing really worth it for growing eCommerce brands? In this episode of eCommerce Masters, host Ethan Giffin talks with William Gasner, Co-Founder and CMO of Stack Influence, about how to make influencer marketing actually work—especially with micro and nano influencers.
William shares how smaller creators (with fewer than 10,000 followers) often drive better engagement and higher conversion rates than celebrities. He explains how Stack Influence helps brands connect with hundreds or even thousands of these creators, without wasting time or product. Instead of relying on follower count, William encourages brands to focus on strong, authentic content that real people actually care about.
He also breaks down product seeding, content syndication, and whitelisting, offering tips on how brands can stretch every dollar by using influencer content in ads. Plus, he shares real examples of what types of products and brands perform best with this strategy.
Whether you’re launching a new product or looking to cut ad costs, this episode is packed with smart, simple advice.
🎧 Listen now to learn how micro-influencers and automation can help your brand grow faster—without breaking the bank.
