It might be tempting to want to offer incentives to customers in order to persuade them to leave a positive review. This is not the best idea for a few reasons.
Offering financial incentives for reviews is against the law and can result in fines — regardless if the review is positive or not.
Paid endorsements are legal as long as it is explicitly mentioned that the reviewer is paid for their opinion, which is not a good look either.
Google, Yelp and other sites have stated that offering coupons or incentives for leaving positive reviews is against their terms of service.
Some brick-and-mortar enterprises may set up a tablet or kiosk for customers to leave reviews while in-store. This is an easy way to “corner” people into leaving feedback when they are put on the spot.
Some review sites do not approve of this and will penalize listings that have too many reviews from the same IP address.
Taking it a step further, Yelp’s terms of service flat out discourages asking for reviews at all. If Yelp sees that a listing is getting many reviews from new profiles or rarely-active users, they consider it “spam” and will either suppress or remove the reviews.
The easiest way to get around Yelp’s “no asking” rule is by making the process of leaving a review as easy as possible. This includes displaying links to your review sites on your website, emails, and other forms of communication with customers.
Taking advantage of Yelp’s free website icons and window stickers is a smart way to grab the attention of avid Yelp users who will be more likely to leave a review, while people unfamiliar with the platform will ignore it.
This way, you are not explicitly “asking” for reviews, but still leaving the door wide open for feedback.
