Fiverrcast has an episode in which they discuss your issue in detail. I suggest you begin keeping records, so that over time you will be able to determine which weeks and months are your peaks and valleys. The transcripts recently disappeared, so you may have to listen to the episode.
See this thread if you have questions for the Fiverrcast team:
You should be aware that Google is in the process of upgrading Translate, so you may be facing new competition with each improvement they make.
I took a quick look at your profile:
Your profile image: I suggest a color image of you smiling.
Your log line: No suggestions.
Your profile text: No suggestions.
All your gigs should have video, 3 images (I suggest personal to you, rather than the stock images you have), 2 pdfs (for translation samples), and so on…
I have a bias against whiteboard videos (I don’t appear in mine because I’m THAT ugly). Make a video of yourself talking to the camera, because this approach garners IMMEDIATE RESULTS. Include additional samples in the video!
Promising to reply within 60 seconds has no value that I can ascertain. I suggest you scratch that claim. It might even turn people off, because it could be suggestive of obsessive-compulsive disorder (OCD) or bipolar disorder. You must be frustrated by Buyers who don’t respond to you for hours or days at a time…
I don’t see why you make translating from Swedish to English such a big deal. I suggest you simply create another gig for that, to increase your exposure on Fiverr.
I also don’t see why eschewing automatic translation tools is an issue for you. It’s like a writer saying, “I won’t use a computer to type your documents, not even an electric typewriter, just this old manual dingus from 100 years ago.” I doubt there are any Buyers who care whether you use translation tools. They just want the job done right and without errors.
The FAQ, “What is required of you?” should probably be “What is required of me?”.
Instead of (or in addition to) the Samples FAQ, make use of your 2 @3-page pdfs to provide samples of your work.
The refund FAQ sounds like a humble brag to me. I suggest rewording it to be more Buyer friendly. Trust me on this – my modesty is my best quality, and all my Buyers love me for it!
Your ordering process FAQ may be off-putting. See previous response about making it more Buyer friendly. There’s more to the order process than you indicate here. You’re lucky that your Buyers are probably smarter than the average bear, but you may also need to point some to the Fiverr Support page and the Fiverr Terms of Service.
Bottom line: your gigs are fine, I’m insanely jealous of your success, and you are probably experiencing a seasonal fluctuation. One can only hypothesize about the causes, such as end of the month / start of the new month, business reasons, maybe there was a big Swiss cheese convention that’s now over, who knows?
