Don’t message people, that’s very annoying. Furthermore, there’s no manipulation going on, people either like your work or they don’t.
Ironically, I hired one of my competitors because I needed a brand name for a new business I’m starting. I don’t like writing for my own projects, and yet I wasn’t crazy about his work. The best he gave me was Vital Vending (it’s a vending machine business), I ended up using an old idea. I’m still happy with his customer service, and I know that writing brand names is very subjective, so I gave him 5-stars. However, if he was a horrible writer, he wouldn’t have 12 on his queue nor would he be in the first row.
Another example was a logo, I paid this guy $30 ($25 for one day delivery) and the first option he gave me was horrible. Then I search on google for the palm tree I wanted, realized the colors I really wanted, and gave him that information. With that, he was able to do beautiful work. I’m proud of the logo I got, it looks like a $450 logo.
My point is there’s plenty of quality on Fiverr, you just have to order and provide instructions. Don’t message unless they want to be messaged.
