I tried everything I can do.I could get only 3 sells.Can someone advice me some tips and tricks to grow up.
Welcome to the Fiverr Forum.
I see from your profile that you’ve received three reviews in a week. You’re already growing!
I understand that you want help optimising your Gigs, though. That’s why I’ve posted a link to a thread on that very topic. It’s a useful starting point.
Here is tip number one above all: Read the Terms of Service. Never break any rules.
I just saw something online about fiverr where someone was advising people to break the rules. That is the stupidest thing you can do. It is not how you do well here.
