If you edit a gig, I would pause the promotion before editing anything. maybe it just me, but I noticed that editing a promoted gig appears to stop everything as in impressions and clicks (i was tracking the impressions and clicks at one point), and they just stopped for days & I had to do something to kickstart it again, and this happened several times
@krheate is a good idea because once the stats start coming in, you start to get an idea of how your gig is really performing. This is my opinion, and I know people will disagree, but you may be getting sales on it, but they may not be as good as they can be (organic, not paid), and by using the promoted gigs in conjunction with making changes to the gig, you will see what works for both organic and paid promotions. In my opinion, the paid promotion results are a good indication of how well the gig is really performing because Fiverr is only pushing the promoted gigs to a targeted audience. If you are not getting conversions there, something is up & It’s time to start looking at what your competitors are doing differently, but you need patience and avoid editing the gig too frequently as the gig keeps getting removed from search each time you edit it, until it updates are approved.
