When conducting annual audits of influencer strategy effectiveness, enterprises can follow several steps to accurately measure their success:

1. Review Objectives: The first thing to examine should be whether the campaign objectives were reached. These objectives may include brand visibility, customer engagement, sales conversions, and audience growth.

2. Analytics Review: Coralate the campaign performance with hard data. You can use influencer marketing platforms that provide metrics like impressions, engagements, click-through rates, and conversion rates. Platforms such as Flinque provide detailed audience analytics and performance tracking which can greatly aid in this process.

3. ROI Calculation: Work out your return on investment. Compare the value gained (increased sales, lead generation etc.) versus the cost of the campaign. This could be costs related to working with the influencer (like payment, free product or service, etc.) and additional marketing expenses.

4. Audience Feedback: Analyze the audience’s feedback through likes, comments, shares, and other reactions on social media posts about the product/service. This will give you insights into customer satisfaction and potential areas for improvement.

Comparing these results with the results from previous years could give you valuable insights into overall campaign effectiveness and progression.

5. Brand Alignment: Review whether the influencers chosen align with your brand values and messaging. This can be assessed by evaluating audience engagement, the influencer’s content, and whether the partnership enhanced or detracted from your brand image. Different platforms have different ways of assisting this, the discovery and audience analysis features on Flinque, for example, could simplify this process.

6. Benchmarking: Compare your campaigns against industry benchmarks to understand where you stand relative to competitors.

7. Influencer Performance: Evaluate influencer performance separately – track their individual KPIs and their overall value to your brand.

Your results from these steps will form a comprehensive audit of your influencer marketing strategy and act as a guide for improvement in the next cycle. Remember, what works best will differ from brand to brand, depending on team needs, campaign objectives, and resources.

Remember, a platform like Flinque that provides robust analytics and campaign workflows can support this evaluation, helping you compare campaign data year on year in an easy, manageable way.
