If you’re trying to give yourself the edge and distinguish yourself from those who are not online, consider the potential gains versus the amount of hassle involved in doing this. Consider the vast time zones and how many people organically remain online at various times during their working day. If you manage to game the system to appear online for more hours than you actually are, how much of a headstart are you actually giving yourself? the front page of any Fiverr category or search page is filled with people who have a lot of sales and positive reviews. Just having a green dot does not elevate your gig in the search results. In fact, it doesn’t achieve anything.
As a corollary, if a buyer sees that you have reasonable response time and 5-star ratings, you are almost never going to be rejected only because there is no green dot at the time the buyer was browsing your gig page. “Seller replies within 6 hours/ 12 hours” is good enough.
In fact, the kind of buyer who expects a reply on the spot might not exactly be the kind of buyer you might adore in the long run. Just write a proper sales pitch and go to sleep. You will have orders when you wake up. Deliver on time.
No amount of gaming on Fiverr generates commensurate positive results. Yet, no one take that advice seriously, they invest too much time and efforts trying to game the system, fail to get and dividends, then complain that Fiverr is too much work.
