For me, a drop in sales is a time to step back, look at my gigs and improve them. No matter how perfect you may think they are, they aren’t. Fix your gig video and make a new one (you DO have a video, right?), and take a look at your gig description from your buyer’s point of view. Are you REALLY the BEST ________in the entire history of humanity? If you aren’t, maybe you should adjust that?
Are your clients native English speakers? Have you had someone proofread your gig description? It may be worth having paying someone or working out a trade deal with someone to do your video, voice over, gig description, etc. This is your business, and you have to invest time, money and effort.
My point here is that your drop in sales is an OPPORTUNITY. Do some maintenance and clean your house (I mean this figuratively as I haven’t seen your place ) Read marketing articles for your field here on Fiverr and elsewhere…there is a wealth of knowledge out there waiting for you. It is in moments of difficulty where you find out if this is right for you.
I wish you all much success!
