Got a few sales!!

Hi, so I started working on a private labelled product a few months ago and now I got it sent to Amazon Fba. After a few weeks of trial and error I started getting sales not much but roughly one every other day. I’m actually very excited about this my plan is the continue with my private label brand and expand and once I start selling more units. Any suggestion on how I can increase sales I have optimized listing with keywords, pictures, video, ppc. What can I do now get roughly 5 sales a day. ( Just trying to be realistic ) Thanks in Advance
