Pro is a completely different type of badge to levels - you can be a Pro TRS or a Pro New Seller for example. Yes, some Pro sellers haven’t really taken to Fiverr (or Fiverr to them) but that’s the same as any seller level too. There is considerable competition even among Pro sellers and those who started well seem to have done well - especially those who were sellers here before Pro.
Since Pro began, there has been an increase in the quality of buyers on the site - not every buyer obviously but there are more small and medium sized businesses willing to pay better rates than the past. This was something I saw was going to happen (and mentioned on the forum) and so without being a Pro seller, I focused more on the types of businesses that I felt would use Pro sellers.
You don’t change a company’s reputation by slapping a black/gray badge on it. Pro was part of an overall strategy to improve the quality of services and reputation of the site. The strategy has worked, in my opinion, but other things were more important than Pro in achieving this - Packages and allowing prices to start above $5 being the main one. The overall improvement in the quality of the site itself - removing the silly unprofessional messages/texts (“Aloha”, “DISPUTE”, etc) also helps.
If Pro isn’t for you directly then that’s not an issue but you can be almost sure it has helped you in sales and that without its introduction and the other changes, your pricing wouldn’t be where it is today.
