How can the future owner improve the business?
I would advise the future owner of the business to focus on growing the email list as it has proven to be very effective in this niche. Create regular and engaging emails to not only make sales but also connect with the audience. I have found that good emails can attract a lot of sales from new as well as recurring customers. I would also recommend launching new product designs regularly. Focusing on Facebook ads would also be ideal as once a winning design is found, the audience has shown to be happy in purchasing a product that resonates with them. Regular Facebook posts that are engaging, funny, entertaining and educating are also beneficial in order to connect with the audience. In other words once again connect with the audience. Also, recently I have also set up Google Shopping Ads, but didn't have enough time to see strong statistics as of yet. I would recommend testing them more as there seems to be potential here.
