Hello sowravnath722,
Here are a few tips you can apply;
Improving your gig image and thumbnail quality-this will separate your gig from other hungry freelancers.
Keywords matter a lot; because buyers search for specific keywords when looking for services.
Constantly updating(editing) your gig will not only lower your gig ranking but also lower its chances of being seen/reached by potential buyers
Otherwise, I'm wishing you all the best in your fiverr journey.
