Copycat websites are imitations of official websites such as government departments or local government websites that offer public services, banks, etc.
There are a number of sites that offer public services – especially visa services, passport services etc. Often these are designed to look official but to charge for services that might in fact be free, or a lot cheaper. When you google the public service website, these often come up first because they use various website tools to achieve higher positions on Google. They also have website addresses that are designed to confuse the person seeking the service into thinking they are official. Google requires companies which charge fees for official services that are available for free, but often this information is in the fine print or not available at all.
