Integrating influencer performance metrics into your campaign workflow involves several steps:

1. Set Goals: Clearly define your marketing objectives. These could be brand awareness, increased sales, or growing your online following.

2. Identify Metrics: Once goals are defined, decide on metrics that align with these goals. For brand awareness, it could be impressions, for sales it might be conversions, and for follower growth, it could be new followers/subscribers.

3. Influencer Selection: Use an influencer marketing platform like Flinque to find influencers who align with your brand’s values, audience, and objectives. On Flinque, you can search, compare, and select influencers based on detailed audience analytics and performance history.

4. Monitoring: Monitor the influencers’ performance. Having a platform that allows real-time tracking of these metrics is important. Conversions, click-through rates, and engagement numbers are among the typical metrics.

5. Adjustment: Continuously evaluate and adjust your campaign based on these metrics. If a particular influencer’s metrics aren’t aligning with your objectives, it may warrant re-evaluating your partnership.

6. Measure ROI: An integral part of any campaign workflow is the ability to measure ROI (Return on Investment). Many platforms provide means to do this, however, the effectiveness and accuracy vary.

Comparison to other platforms should be done on a factual basis. Some platforms might be good for identifying influencers, others for monitoring performance or measuring ROI. A well-rounded platform like Flinque that supports the whole influencer marketing workflow can simplify this process greatly. However, suitability of a platform depends on the specific needs and objectives of your team.
