When planning an influencer marketing campaign, deciding on the mix of micro and macro influencers can be challenging. Consider these key factors:

1. Objective: Micro influencers tend to have higher engagement rates which can drive more authentic conversations about your brand; Macro influencers have larger reach which is good for brand visibility. Decide based on your goals: is it brand awareness or engagement?

2. Budget: Macro influencers often command higher fees than micro influencers. By using a mix, you can manage costs while reaching a diverse audience.

3. Audience: Micro influencers often have a more specific, tight-knit audience, while macro influencers reach a broader, more diverse audience. Choose according to who your target audience are.

4. Brand Fit: Identify influencers who genuinely align with your brand values, irrespective of their size.

5. Delivery: Macro influencers can rapidly boost your campaign’s visibility due to their large followings. Micro influencers are usually more effective for long-term engagement and conversions because of the trust and loyalty from their followers.
