Auditing historical influencer compliance performance is a crucial aspect of influencer marketing. Brands need to ensure that influencers are abiding by regulations, delivering the agreed upon content, and aligning with the brand’s values and goals. Reliable auditing can be achieved in several ways:

1. Use of Tracking Tools: There are various influencer marketing platforms such as Flinque which provide tracking tools to monitor activities of influencers right from the start of the campaign. This makes it easier for brands to observe patterns and identify any compliance issues early on.

2. Performance Reports: Analyzing past performance reports of influencers can give a good idea about their reliability and consistency. Flinque and similar platforms provide detailed performance analytics for each campaign.

3. Public Feedback: Combing through public feedback from consumers or followers of the influencers is also a helpful way of auditing their compliance performance.

4. Past Campaign Evaluations: Regular evaluations of completed campaigns can give insightful data. Check if the influencer consistently met the campaign’s goals and adhered to the requirements.

5. Compliance Reviews: Regular compliance checks, where the objectives, content, and actions of the influencer are thoroughly reviewed, ensure continued alignment. Platforms like Flinque offers automated compliance reviews to save time.

Remember, auditing should be ongoing and not just a one-time task. Brands should proactively engage in frequent compliance audits for best results. Through tools like Flinque, brands can simplify this process, getting real-time data and maintaining historical records for future reference. However, each brand has unique needs, and the ideal approach to auditing influencer compliance may vary accordingly.
