Ad credits are a form of currency that can be used to pay for advertising on various online platforms, such as Google Ads, Facebook Ads, and Twitter Ads. These credits are typically offered as a promotional incentive by the advertising platform, and can be earned through various means, such as signing up for a new account, referring friends, or participating in surveys. Once you have ad credits, you can use them to create and run ads on the platform, targeting specific audiences and demographics. Ad credits are a great way to get started with online advertising, as they can help you test the waters without having to invest a lot of money upfront. However, it is important to use them wisely and strategically, in order to get the most out of your advertising budget.
