Okay, if I were you, I'd restart selling services on Fiverr as something new. (However, the choice is yours.)
Your gig title is entirely critical. on some buyers psychological side, they are unable to search you when using specific keywords.
for your better performance, advertise your gig through social media like facebook, Instagram, and YouTube.
There's no point in creating more gigs with critical SEO titles. I'd say research more about what you are trying to offer as a service.
