Should I edit my under performing gig?

[taskarmy]

Hello there,
This question may be outdated but I need some updated help! I have a fiverr gig with 24 sales & 5 star reviewed. But suddenly the gig impression, views and everything went down. My description and tags are not that good. So should I edit that under performing gig?

I heard that if you enroll fiverr success course, editing gig doesn’t effect rankings. Is that true?

Thanks in advance
