signature9, it's funny you mention this because my situation is identical to yours. I'm a Top Rated Seller with about 1.3K 5* reviews, and have consistently ranked on the 1st or 2nd page for my niche. I typically received 200 or so clicks daily and multiple inquiries. I was selected as fiverr's choice for a couple of weeks, then immediately I fell off the radar. Since then, my clicks are 4-20 per day with virtually no inquiries or orders. I can't find my gigs through standard searches (I think I'm below page 20 which is where the search ends). However, my gigs are active because I can search by seller level and I'm the very last listing in the TRS list of approximately 45.
Anyway, I'm sorry I don't have anything meaningful to contribute here, other than things have been quiet for me since the 3rd March and show no signs of improvement. I have reached out to customer support, but as expected, there's no further insight they can provide (other than I haven't contravened any rules/guidelines). I'm now running low on orders for the first time in years, so weighing up my options. I think the Promoted Gigs option has promise, though this would be speculative, and of course has no guarantees. Failing that, I'm hoping I can purchase some services to increase my visibility, and hope that with a little boost, my previous record of quality will entice new clients to purchase.
