Thanks Turboquid, we appreciate that! Do you mean you use tag autosuggestions? They were developed to help designers write related tags. If there is any feedback about the functionality please let us know.
We also analysed sales correlation with how many tags models have and saw that models that have 10-15 tags have on average 2-3 times more sales than those that have only minimum 5. So take your time to write more tags, they are quite important to attracting customers to your product page. But don't spam, because unrelated tags doesn't help.
