Social Media Marketing Agency FAQs

The average conversion rate that brands can see across all objectives is 1-2%, with top-performing campaigns reaching 3% or more. 
  • Influencer marketing helps brands spread the word about their products or services by partnering with influencers who will feature the brand in their digital content. As research suggests, 69% of consumers are likely to trust an influencer's recommendation over information coming directly from a brand.
