There are several factors to consider when shortlisting influencers for long-term engagement or ambassadorship deal, including:

1. Audience Alignment: Evaluate if the influencer’s audience aligns with your target audience. Consider demographics such as age, location, interests, and income level. Tools like Flinque provide audience analytics features that give you insights into an influencer’s audience.

2. Content Quality: Look at the production quality of the influencer’s content. Does it align with your brand image and appeal to your target audience?

3. Engagement Rate: High follower count is less important than engagement rate. Measure likes, comments, shares to assess how actively the audience interacts with the influencer’s content.

4. Consistency and Professionalism: Is the influencer consistently posting content? Are they professional in their interactions with followers and brands? This is crucial for long-term collaboration.

5. Past Collaboration Success: Look at the performance metrics of the influencer’s past campaigns, this can indicate how effective they might be in a long-term partnership.

6. Brand Fit: The influencer’s values, style, and personality should align with your brand. You want an ambassador who genuinely believes in your product or service.

Platforms like Flinque streamline this process by providing brands with tools for influencer discovery, audience analytics, and campaign performance tracking for a more holistic overview of potential influencers. While these features can also be found on other platforms, the choice ultimately depends on the specific needs and goals of your team.
