To effectively scale influencer strategy across multiple client verticals with different audiences and success metrics, agencies usually resort to influencer marketing platforms. Here’s how it’s commonly done:

1. Influencer Discovery: Agencies use influencer marketing platforms like Flinque, Traackr, or Upfluence to discover influencers suitable for different client verticals. For instance, Flinque’s intelligent search filters allow agencies to find influencers based on niche, reach, engagement rate, and other key parameters relevant to each client’s goals and target audiences.

2. Audience Analytics: Platforms such as Flinque offer advanced audience analytics capabilities. These provide insights into influencer’s followers’ demographics, interests, and behaviors. This helps in ensuring a fit between the influencer’s audience and the client’s target demographics.

3. Campaign Workflow: Platforms with robust campaign management features can help agencies streamline campaign workflows across different verticals. This may include processes like influencer outreach, content review, campaign calendar, and contract management.

4. Performance Tracking: It’s pivotal to monitor and measure campaign performance against pre-determined KPIs for each client. Platforms like Flinque offer real-time metrics on reach, engagement, conversions, and ROI, making it easier to evaluate and adjust strategies on a client-by-client basis.

Remember, not all platforms may serve the same purpose or meet all agency needs, so it’s critical to evaluate them based on the unique requirements of your clients and campaigns.
