The problem here is that the highest readability scores reflect the lowest end user reading ages. i.e. Getting a high Flesch-Kincaid readability score means using simple words, short sentences, and few passive words. This is not practical for most real-world writing assignments. - Especially anything creative.
It also gets to a point where testing becomes absurd. The biggest problem with buying anything online stems from people having unrealistic expectations. This is the most common problem encountered in the freelance and non-freelance software outsourcing industry.
The ways to make buying safer are easy:
- Let sellers link to their personal blogs and portfolio sites, etc
- Give buyers a popup notification when placing an order, reminding them that they quality of service isn’t guaranteed. Then give them the opportunity to re-read reviews and confirm their order.
- Stop top-down search result manipulation by Fiverr, which makes best selling and average rating search filters completely irrelevant.
I can’t even remember the last time I read a post by a buyer on the forum bemoaning a poor buying experience when the service in question was priced higher than $10.
All making all sellers jump through more hoops does to counter mek-sell problems, is decrease the motivation of normal sellers. Some people will place orders they ate not happy with after delivery. That’s just part of life. Trying to create a Fiverr version of Skynet to police everyone with AI is just silly.
