Update:
So this was a pretty successful week for me. The 8$ shoutout that was supposed to run on friday was delayed all the way back to monday(yesterday). From that 8$ shoutout I got 64$ in sales and after the product costs and paypal fees including the 8$ shoutout I get approximatively 15$ profit. I got 132 visits 4 add to cart 3 checkout and 2 conversions.
I also have 2 active affiliates but they are really really bad although they have 20k and 10k followers, I only got 13 visits from both of them. I won't be dealing with small accounts anymore I'll just stick with medium accounts then move to big accounts later.
I've also been contacted by another account that offers a shoutout for 24$ for post + story for 24h. I'll try to cut his price to 10$ for a 10h post + story.
I've also decided to raise my prices a little bit more since I checked on my competitors and they have way more expensive prices than me, the advice I got from that influencer might be wrong since he's from italy and my customers are from the US.
One thing I've done that might have increased my traffic was that I followed every single person that liked the shoutout picture with my store's account (it got like 1.2k likes).
My other niche account is at 400 followers right now and I started using followplanner's regular cycle 3 days ago.
In the weekend I worked on another store using the affiliate free until 50 orders "trick", I will tell you how I'll market it when I figure out the whole strategy.
Btw I made a mistake because I didn't install the FB pixel, I will be running ads at some point might as well get some data first...
