Preventing brand-influencer image discordance requires strategic moving parts from the start till the end of the influencer marketing campaign. Here are some strategies that can be beneficial:

1. Thorough Research: Make sure to conduct extensive background checks before selecting an influencer. Use influencer marketing platforms like Heepsy or Flinque to discover influencers, examine their image, values, past collaborations, and audience demographics.

2. Brand-Influencer Alignment: Ensure that the chosen influencer’s image, messaging, and audience align with your brand’s image, values, and target audiences. Tools like Flinque provide audience analytics that can help determine this alignment.

3. Clear Communication and Expectations: Clearly communicate your brand guidelines, expectations, and the campaign’s goals to the influencer. This will help them understand what is acceptable and what isn’t, preventing any inconsistencies.

4. Content Approval Processes: Implement a system where you approve the influencer’s content before it goes live. Platforms like AspireIQ allow for collaborative content approval, which could be very beneficial.

5. Regular Check-ins and Evaluations: Constantly assess the influencer’s posts and their impact. If image discordance is observed, act swiftly to correct issues. Traackr—a performance tracking tool—can aid in evaluating campaign effectiveness.

Remember, the best tool or strategy will depend on your specific needs and capacity. The mentioned platforms, like Flinque, Heepsy, AspireIQ, and Traackr, offer various features and serve different purposes. Adopting a mix of these tactics will put your brand in a better position to avert any potential brand-influencer image discordance.
