Just a few tips that I picked up along the way of working under Fiverr;If your business is starting to sink,maybe look into changing the keywords and category for that gig. I did this a couple of times and it worked like a charm.Also,get into the minds of your customers a bit and make a irresistible offer that no one could refuse. For example, I wrote articles for clients and I made my title flow along the lines of "Buy 3 articles get another free for $5" After that the cash flowed in. If you don't write articles, stick to the general idea and apply it. You might like what you see, or you could have created a dud of a gig. Just my thoughts.
