What I’m trying to say is that at the beginning you don’t really need to worry about impressions. You need to work on turning impressions into clicks and clicks into orders.
However, I checked your gig and if you’re getting a very low number of impressions then it could be that your target audience is not on this platform. You might need to reach out to social media groups or communities.
I took the keywords “climate change” from your gig and it seems that there are less than 10 gigs that offer it. Why? Maybe there’s no market for it here.
Or maybe people use different keywords to look for that kind of service.
So you can optimize your gigs for different keywords & tags, but if that doesn’t work either then you might need to bring your own clients here.
Look up your closest competitor and check what kind of keywords are they using.
