It’s becoming increasingly important for businesses to be listed on review websites and various other portals. These, usually large, websites are where people go when they're looking for advice for a particular problem, a comparison of two or more competing products or services, or reviews of whatever they're planning to buy.
There are countless websites of this kind, and they cover pretty much every area of life and various types of goods. We're talking about TripAdvisor for hotels, Capterra and G2 Crowd for software, LegalMatch for attorneys, Zocdoc for doctors, etc. You get the idea.
