I also have some stats here and I probably will say that I’m overall satisfied with promotion feature.
It didn’t make a big difference in terms of monthly income but ROI is definitely quite high.
These are stats for the last 3 months, which brought me 4 orders with a spend of 6$ only over 90 days
I will have to look deeper into the analytics and check if my impressions indeed decreased after I edited my gig.
What I did notice that on my promoted gig I started getting at least 2-3 messages every week from new sellers asking me to give them orders or just “hi how are you” messages.
So half of my promoted impressions definitely went for those sellers who saw “ad” on my gig and decided to click on it on purpose.
