No, there hasn’t been any updates on the testing, if they are ongoing/complete/taking a break or whatever.
The thing is, no matter what happens in the coming months, there will likely still only be 48 places on the first page and thousands of sellers seeking to get them. Getting to Page 1 is fantastic for those who get it, that is clear and I have seen the difference myself recently before being moved back down the list…
And that’s the thing to take from this whole “experiment”. You cannot and should not rely on search position. Of course, do whatever Fiverr suggests is important and whatever common sense things you see fit to do but the bottom line is that the odds of ranking on page 1 are stacked against the majority of sellers, so why keep rolling the dice?
Take the steps necessary to at least somewhat guarantee your income by taking the matter into your own hands and IF you get page 1 then take it as a temporary bonus regardless of how long (or short) your good fortune lasts.
