How to Measure Influencer Campaign Success for Ecommerce

According to Neilson IQ, TikTok Shop was the fastest-growing online retailer in 2024. For brands, this is a clear indicator that influencer-driven commerce is transforming the way people shop online.

As influencer marketing becomes more intertwined with ecommerce, it’s no longer about surface-level stats. If the campaign is aimed at driving sales, brands need to go beyond vanity metrics and focus on the ones that deliver real impact.

To understand best practices for measuring the success of influencer campaigns, we spoke with Sarah Jardine, our Senior Strategist.

“The path to purchase isn’t linear. Research suggests consumers need to see a brand message at least seven times before converting.” So, how can you be sure your influencer campaign is moving the needle on sales? That’s where efficient tracking, real-time optimisation and a holistic strategy come in.

Building a conversion-first framework

If you can’t measure it, you can’t scale it. Here’s how to build a clear measurement framework for influencer-led sales:

1. UTM Links: Give each influencer a personalised UTM tracking link. It lets you follow the consumer journey from post to checkout.

2. Promo Codes: Assign unique discount codes to attribute revenue and incentivise action.

3. Landing Pages: Build unique landing pages per influencer or campaign theme. Use Google Analytics to see what’s driving clicks and conversions.

4. Affiliate Links: Set influencers up with affiliate links to reward based on performance. It’s scalable, trackable, and ideal for ecommerce.

What high-performing campaigns get right...

Standout influencer campaigns aren’t static but evolve in real-time. Success comes from a test-and-learn strategy where A/B testing is integrated from day one. Whether it’s testing creative formats, CTA placements, or influencer archetypes, the top-performing campaigns are the ones that adapt as a campaign runs.

And while reach can be impressive, it’s conversions that ultimately count. It’s not just about how many followers an influencer has, but how engaged and loyal their audience is. The most effective campaigns bring together a mix of influencers to tap into niche voices. For ecommerce, ROI should always outweigh vanity metrics.

How can you use social listening?

Want to know how your campaign is performing in real-time? Tune in with listening tools. These capture live audience reactions, spotlight sentiment shifts and help you track your brand’s share of voice across platforms. More than just insights, it’s a tool for action. If the tone, creative, or influencer mix isn’t hitting the mark, you can recalibrate on the go. The result? A campaign that doesn’t just run but responds and delivers.
