I do post regularly on certain forums and use this tactic (once you build a reputation as a helpful user and solid English speaker, it definitely works to increase sales), however, I’m also looking for sites that sell banner ad spaces.
You can place a 728x90 ad at the top of The Warrior Forum for $59/10,000 impressions. If you’ve got the right ad design, it will definitely pay for itself (and then some) You could even use Fiverr Anywhere to create a link so they’re taken directly to an offer page. I’ve never tried that, but I have read about it working for some people.
I have marketing experience for other things but I’m still pretty new when it comes to marketing my Fiverr Gigs. My sales are still good, but I’ve finally come to realize that Fiverr’s search algorithm may not be reliable on a day-to-day basis forever (so I’m looking for other ways to get clients). I sell things off-site for more but I actually much prefer Fiverr’s platform and ease of use. I always know there’s a layer of protection for payments, and to me, that’s worth them taking 20%.
