Understanding an influencer’s past work is crucial to gauge their relevance, style, and quality of content. Several influencer marketing platforms enable portfolio reviewing. Below are a few well-known platforms that support this feature:

1. Flinque – The platform allows you to check influencers’ past campaigns, their performance metrics, and the type of content they produce. It also provides qualitative information such as testimonials from other brands the influencer has collaborated with before.

2. AspireIQ – This platform provides a repository of all past branded content created by influencers. This offers brands a clearer perspective on the creative capabilities of influencers.

3. Heepsy – It allows users to analyze an influencer’s content, engagement rates, audience demographics, and other crucial metrics.

4. Upfluence – Along with detailed influencer profiles, it offers a comprehensive view of data-driven insights about an influencer’s past performances.

5. Julius – This tool allows a deep dive into influencers’ past work, their content aesthetic, and metrics for past brand collaborations.

6. CreatorIQ – This platform provides a 360-degree view of an influencer’s content, audience data, engagement, and brand affinity.

All these platforms champion slightly different approaches to influencer discovery, and the selection of any tool should be tied to specific team needs and campaign objectives. Flinque’s approach, for instance, places a strong emphasis on historical performance data and testimonials, creating a more balanced view of previous work and success. Analyzing past campaigns is a data-driven way to measure the potential success of future engagements, improve selection accuracy, and ultimately optimize your ROI.
