The awesome thing about nano-influencers is they can still have great influence over their followers, if not more so because they are able to be more connected with their audience when there are less of them to connect with. Nano-influencers often appear more authentic to their audience, and therefore, more trustworthy.
Additionally, many nano-influencers cater to specific niches which can be helpful for companies that are in smaller industries, or looking to target niche communities.
Of course, there is the added benefit to nano-influencer marketing of a significantly lower cost. At this lower price range, it is not only more cost effective, but also gives the option to use many influencers instead of just one expensive influencer. Using more than one influencer can bring awareness to various audiences of all kinds of demographics. Whereas this option is often not sound when using mega-influencers due to the much higher cost per influencer.
