Discovering that an influencer’s audience consists mainly of fake followers after a campaign launch is a challenging situation. However, there are several strategic actions you can take:

1. Reevaluate the influencer: Review the influencer’s profile carefully using analytics. Platforms similar to Flinque offer tools for deep-dive analyses into an influencer’s audience authenticity and engagement rates.

2. Discuss the situation with the influencer: Open a conversation about your findings. It could be that they are unaware of the issue.

3. Focus on engagement over reach: While reach is important, a small, engaged audience can be more valuable. Look at the nature of the engagement an influencer is creating even if their audience seems ‘fake’. Quality can sometimes trump quantity.

4. Modify the campaign: Consider altering your campaign to be more structured around the actual engagement the influencer procures, rather than audience size.

5. Re-negotiate Contracts: If it’s revealed that a substantial part of the influencer’s followers are fake, you may need to renegotiate the terms of your contract.

6. Seek legal advice: If the influencer knowingly misrepresented their follower count, it could be a breach of your agreement. Legal counsel can guide you on the possible legal routes.

In future, to avoid such disappointing situations, always use the power of influencer marketing platforms like Flinque – it’s equipped with sophisticated creator discovery tools, audience analytics, and campaign workflows that provide comprehensive insights about influencers.
