Black / White lists are functional tools in the "Audiences" section that allow advertisers to have more precise control over where their ads will be displayed.

White Lists:

White Lists are a list of platforms or websites to which an advertiser grants permission to display ads. When you add a platform to the White List, your ads will only be shown on the sites you specify. This allows to target more precisely the audience and ensures the presence of ads on platforms considered most relevant and safe for your brand.

Black Lists:

Black Lists are a list of platforms or websites where an advertiser prohibits the display of ads. If you add a platform to the Black List, your ads will not be shown on the specified sites, even if these platforms are part of the advertiser's overall network. This allows you to prevent ads from being placed on unwanted platforms, helping to protect your budget from unwanted expenses.

It is important to set the lists correctly to ensure the maximum effectiveness of the advertising campaign. Make sure that all values in the lists are written in a column without commas or other punctuation marks to avoid errors and accurately specify the necessary platforms for each list.
