I have been working fiverr for 6 months and I reached Level 2. During this time period of struggle because of the competition in health and fitness section, I learned five things from fiverr which can be applicable to any field.
1-Do research before creating a gig.
2-Adopt low competition and highly demanded strategy on Fiverr.
3-Add brief description.
4-Use Yahoo answer to get Sales and Traffic
5-Deliver before time.
After all, your reputation as a dependable seller will go a long way.
