Thanks Xeisenberg, however I'd beg to differ for a number of reasons:
1. With competitive products, where there are numerous alternative vendors offering their products at a similar price, it helps to be able to stand out. If you have 2 products, where the only difference between the two is that one is more professionally presented, X would most likely select that one.
2. Some products are not simple - unique products that are complicated and therefore difficult to explain, may require very careful wording. If the product is what the potential buyer needs, but it isn't clear and the potential buyer can't be doing with the hassle of requesting clarification via PM, it is certain that if the product was worded more clearly in the first place, the sale would be made. I worked on a couple of products like this - such as custom-built encrypted laptops with deep technical specs - for vendors on the previous Silk Road, and was commended by the sellers for the difference it made.
Although you would think that a poorly worded product listing would sell just as well providing it was what the buyer wanted, comments I received before testify against this. I remember one vendor (of a very common product - and his description did the job of saying exactly what it was) writing to me and sending a bonus because his order rate doubled within a week. This could have been put down to coincidence, but I've done this for many years now in the real world, and I believe the same consumer psychology principles apply here.
Again though, thanks for the input I appreciate it.
