At a glance, the freelance sphere on Fiverr is differentiated by the high price tags as seen on Pro gigs.
What comes into my mind is the fact that most people know Fiverr as the $5 Website. With this thought - for me I think, new buyers who are visiting the site for the very first time will be hit by the high price tag as seen on Pro gigs. When this phenomenon happens, then the outcome will be two things - either the dodge off to gigs with low prices or they bounce off the site.
I also think that any company churning out between $200 and $400 to acquire a service ( especially for a writing gig) on fiverr is capable of getting a full time employee. Leaving out some of the professional gigs like Voice Overs and Explainer videos, rushing into being a pro on fiverr has an uncertain outcome.
Talking about returning buyers; I believe for most freelancers who have been accepted into the Pro game is surely a top rated seller. Before being a top rated seller, you must have achieved a certain level of success here on fiverr and that includes giving all of your best in other to maintain the fiver stars streak. So, as a pro, who is also a top rated seller, how do you convince your buyers to churn out such amount for the same quality they have been getting from a top rated seller.
Theoretically, I see no difference between a pro and a top rated seller other than the spellings. I stand to be corrected. I am in a rush and have to hit the road - if you find any grammatical blunders or spelling errors, laugh it off.
