The Poker Welcome Bonus, more commonly known as the sign-up bonus, is a way to greet you as a new customer, giving you a good start when depositing for the first time. Usually you will be offered credits equal to a predefined percentage of your first deposit. The most common one is 50% - 100% meaning that if you deposit €50, you will be credited another €25 or €50, adding funds for you to use when playing poker.
