I totally agree with @uzzal32. I'm also fighting with every techniques I found on the earth of internet but any of them don't work for me.
I'm an SEO expert. As a result, there is nothing left to optimize gig SEO. My gig performed in the 3rd page instantly after optimizing it. But it doesn't go up anymore. I analyzed lots of gigs and found that most of the gigs aren't optimized but in the top position. I achieve a good rank on Google for my website against my SEO efforts but why it doesn't work on Fiverr? Everyday I am suggested to improve gig SEO. But I got tried to hear this tip. Fiverr is totally different than search engines. I think there is only a effective way to get orders as a new seller, drive few clients from outside and earn some reviews which are quite difficult task.
Finally, while survival on Fiverr is not impossible, it is difficult for new sellers. Never, ever give up hope.
