Often when businesses ask for reviews users get sent down one of two funnels. These funnels are executed using either an email drip campaign, a text message campaign, or a platform in-store. The two funnels represent whether a customer had a positive experience or a negative experience.
For the last eight or so years, I have seen most brands funnel a good experience to a live third-party website so the review can be displayed on the web, Google My Business for instance. For customers with a bad experience, however, brands want to funnel these to a customer service rep or feedback form so that improvements can be made, and the reviews are never published on the web.
What is really wild is that in the last year I have seen many brands paying customers off for reviews, offering $25-100 gift cards when customers are willing to leave feedback. This creates manipulation in the review market. I personally have made about $300 in the last year or so leaving reviews and getting paid for doing so.
