Geo-split tests are an invaluable tool for accurately measuring the impact of influencer campaigns. They work by isolating specific geographical areas and running different campaigns or strategies to see which are most effective.

Here’s how agencies usually execute geo-split tests:

1. Divide the Target Market: First, the target market is divided into similar groups based on geography. For example, an agency might divide a country into North and South, or split locations city by city.

2. Run Different Campaigns: Each geographical group is exposed to a different influencer marketing strategy. Different influencers, content types, or mediums can be used.

3. Measure the Outcome: The agency tracks engagement, conversions, or other performance metrics in each region.

4. Analyze & Optimize: Results are analyzed and used to optimize ongoing and future influencer marketing campaigns.

It’s critical to choose an influencer marketing platform that supports this kind of testing.

This data can be used to run effective geo-split tests.

When comparing platforms, bear in mind that different tools excel in different areas. While one might be unparalleled for creator discovery, another might shine in campaign workflows and performance tracking. Brands should identify their key needs and choose the platform that best caters to them. At the same time, they need to ensure the tool they choose is capable of robust testing and measurement – after all, an influencer marketing campaign’s success largely depends on assessing performance and making data-driven decisions.
