Don’t do it. It’s not a good idea to buy your own gig on Fiverr or any other online marketplace just to boost your ranking. This breaks Fiverr's rules, and you could get your account suspended or even banned.
Fiverr’s algorithm ranks gigs based on things like positive reviews, how often you complete orders, how fast you respond, how quickly you deliver, and how happy your customers are. To improve your ranking, focus on providing great service, delivering on time, and keeping good communication with your customers. Promoting your gig on social media can also help more people find it.
Buying your own gig might give you a short boost, but it can hurt your reputation and get you in trouble with Fiverr. It’s much better to grow your Fiverr account by offering top-quality service and sticking to their rules.
