Alright, converted my lesser performing accts into tangentially related ones to the niche which was working the best. Sales are a bit more numerous now, but not quite what I want to make.
Using free hootsuite now since 3 accts were already hitting the 350 mark.
Getting at least 1 sale per day now. Once I optimize that, I'll look into proxies/other niches though I'm worried about connecting them with my shop. Maybe I should open another?
2 accts in particular are doing very well. (1.5-2k followers per week) and another has a loyal followbase, very like/rt happy. The rest are meh, gonna try optimizing them.
