It happened to me as well abruptly, starting from October 1st. Like, on September 30th I had 7-9 orders a day and the next day it all went to 1-2. My response rate fluctuates around 87% - 93% my whole time on fiverr, no abrupt changes there and I’ve never noticed any connection between it and my gigs’ popularity. But when it comes to sales, it’s the lowest point in 6 months I’ve been here.
I thought maybe one of my gigs was featured or was put in “recommended” category (I have one that is much more popular than the other ones) and then removed/moved down by the new ones. I mean, I’m out of theories, but this one is as good as any.
Also, fiverr’s been all glitchy as hell since late August. I had buyers complaining the gig was “unavailable” (while for me it was perfectly fine), messages would disappear or get stuck, etc. So maybe there is general availability problem, as well.
