The open-access publisher Dove Medical Press has a controversial past and I have written about the company on a number of occasions. .
Don't wait too long to ask for a review because customers are busy, and their lives move on very quickly. Aim to reach out immediately after you finish conducting business; for example, a house painter would connect with a customer after they have wrapped up a painting job. Depending on the products or services you offer, it might make more sense to wait a few days or a week to give the customer time to experience the benefits of whatever they have purchased. Don't just think about timing in terms of the specific part of the sales process in which you make your request, but also consider the appropriateness of each situation. For example, if a customer has just expressed their frustration or dissatisfaction, it's probably not a good time to ask for a review. Instead, wait until you've been able to resolve their issue (and hopefully go above and beyond). If they mentioned being appreciative of your willingness to make a situation right, that could be an ideal "window."
