With the ever increasing popularity of online shopping，users' reviews（評(píng)價(jià)） are becoming more and more important.Since you can't actually touch，see，smell or hear the product your buying online，these reviews provide buyers valuable information on the product itself.But how reliable（可信的） are they？
    Bamaby Bicken took some friends to a restaurant in Manchester that had excellent reviews on a food website.However，she found the service was awful. "We were ignored（被忽略） most of the time.Later，I wrote a reviewer to the same site only to be told that the reviewer site owner would not accept any bad reviews only the good ones."
    So，how can you get a useful review？Web expert Hilary Saunders has a few top tips. "If there are only a few reviews of a place，it is quite possible that they have been posted by friends or enemies.If there are many reviews，don't pay attention to the most extreme comments.Also，watch out for the reviews that are almost the same in style and are placed at about the same time.jye.ai though they are from people with different usernames.The best thing is to look for reviewers who seem to be familiar with the product they are reviewing.
    Although some companies still offer gift voucher（禮券） to anyone who would give their product a five-star review，some are stepping in because they think it's their duty to build an objective（客觀的） image of their product."Amazon works hard to keep its customers' reviews complete." said a spokesperson for the company."We have very clear rules，and when a customer reports a reviewer that we feel inappropriate（不合適的），we check and may take it down."
    So next time you see that five star review for something you want to buy，be careful-it could be the work of a false reviewer!
