Given the growing importance of social media influencers in ecommerce, it’s surprising that more merchants and brands aren’t using them on Prime Day, based on results from a new survey from Revfluence.

The company, which has a network of 500,000 social media influencers, conducted a survey on Google from July 11 to July 12, with 272 respondents. They found that only 11% of influencers planned to work on behalf of brands during Prime Day and a half.
