It is interesting to consider the big picture that Fiverr is looking to implement here. The majority of new features as already mentioned appear to be about strengthening the relationship between buyers and sellers (gig videos, milestones that can include zoom meetings, display name, etc.). I can also see them taking further steps towards making this connection instant. Perhaps a stronger emphasis in the algorithm to recommending currently online sellers, increasing the probability of a near instant reply and thus, the start of a transaction.
Also looking at current societal trends we can see that there is a large emphasis at the current time for 'shopping local'. This is an unusual concept here considering the power of the internet and this platform allows you to access services from people worldwide, but buyers do already have filters to refine their search to both local and online sellers. I think it is possible that both of these properties could have increased emphasis on the algorithm going forward.
With regards to Buyer Satisfaction Rate (BSR), I do wonder how they balance this out in terms of financial gain/loss. A well respected 5 star seller who on average gets 2 orders a day, will be providing a good amount of revenue to Fiverr through their sales. So if their BSR drops resulting in them not receiving orders for a few days, surely this has to be balanced out with whatever data they hold on the probability of new buyers becoming repeat buyers?
