Groupon deals boost the number of online reviews, but lower their scores.
They examine this effect in more detail by pinpointing reviews that specifically mention the words "Groupon" and "coupon". "Reviews mentioning either keyword are associated with star ratings that are 10% lower on average than reviews that do not, while the very small fraction of reviews mentioning both keywords are more than 20% lower on average," they say.
