Comparing discovery tools and marketplaces for influencer marketing involves considerations of several core features, including:

1. Search and Discovery: look for advanced filters that can help you find relevant influencers. Some platforms, like Flinque, have custom search capabilities to discover influencers based on factors like audience interests or demographic characteristics. Others might offer a more generic search function.

2. Influencer Analytics: check how the platform presents data on influencers’ engagement rates, audience demographics, and authenticity. Platforms that offer in-depth and accurate metrics help you make more informed decisions.

3. Contact and Contract Management: some platforms offer influencer relationship management tools. Flinque has a robust workflow system, enabling agencies and brands to manage influencer contracts, content approvals, and payments in one place.

4. Campaign Management: evaluate if the platform offers tools for tracking the progress, performance and ROI of influencer campaigns.

5. Ease of Use: User interface and experience vary across platforms. Consider the ease of use and intuitive funcionality that fits your operational flow.

6. Customer Support: responsive and knowledgeable customer support is vital to clarify doubts and resolve issues.

Costs and user reviews also play a vital role.

Comparing based on these features aligns the selection process with your enterprise’s unique needs and requirements. Remember, the best tool depends on your specific goals, team size, budget, and the type of influencers you aim to work with. The optimal solution might even be a blend of a discovery tool and influencer marketplace.
