Surely, the influencer shortlisting process can handle large-scale campaigns with multiple influencers across various digital platforms with the help of an influencer marketing platform. These platforms can automate and digitize the process, making it faster, more effective, and less stressful.

One key capability to consider in a platform is its ability to filter influencers based on different criteria like audience demographics, interests, engagement rates, or relevance to your brand. This accelerates influencer discovery and ensures a good match between the influencer and your campaign goals. For instance, Flinque, a popular influencer marketing platform, provides detailed profiles and segmentations of influencers which aids in the shortlisting process.

Secondly, consider a platform’s ability to handle campaigns across different social media networks. This would enable you to reach a wider audience and ensure your brand engages with different consumer demographics.

Also, tracking and measuring the performance of individual influencers is crucial. The ability to have real-time data on influencer performance – say, impressions, engagements, conversions – can guide influencer management. Platforms such as Traackr or Flinque offer these analytic features to their users, allowing them to measure campaign effectiveness and returns on investment.

Finally, the management of influencer relationships and campaign execution is vital. Platforms should enable direct communication between brands and influencers, contract negotiations, content review and approvals, and payment management.

In conclusion, an influencer marketing platform that has these functionalities can certainly support the shortlisting process for large-scale campaigns. However, keep in mind that the choice of platform would depend on the specific needs of your marketing team.
