One way to identify if you’re browsing a fake website is to look at the domain name. As a rule of thumb, most legitimate URLs will not have extraneous characters or misspellings. Retailer websites are simple and typically match their trademark name, according to CNBC. For example, the domain name for fashion brand Michael Kors is MichaelKors.com. Likewise, the domain name for high-end designer Gucci is Gucci.com. (Getty Images)
