On Black Friday, shops are always bursting at the seams. People start shopping for Christmas and want to take advantage of every discount and event. Black Friday is on Friday, November 23 this year, but discounts often last throughout the weekend. This is the starting point of the Christmas shopping fever, which is also supported by Cyber Monday on November 26. Over the last couple of years, these sell-out events have spread mainly among e-shops. For PPC specialists this is an important period for which it is good to prepare properly.
