Hi there. That’s pretty great that you got 2 orders so soon after joining, many sellers have to wait much longer for that, probably even more so now, as there are so many new sellers due to the pandemic situation.
Some more possible factors to consider:
How you see your gigs ranking may not be how others see your gigs ranking.
If two of your gigs sit right next to each on the first two spots on the search page, are they really different gigs, or is one a duplicate gig, i.e. basically the same gig? Duplicate gigs aren’t allowed, so that might have some influence too.
Your profile, gig description or sample images might have spelling errors, which some buyers might not notice, but others might, maybe make sure that isn’t the case.
