Ads.txt Manager is a free WordPress plugin designed to simplify the management of ads.txt and app-ads.txt files directly from your WordPress dashboard. This tool caters to publishers looking to control their ad inventory effectively, ensuring compliance with the Interactive Advertising Bureau's initiative. It requires PHP version 7.4 or higher and WordPress version 6.3 or above. With built-in validation features, it helps prevent errors in the ads.txt file that could lead to revenue loss due to caching issues.

The plugin's functionality extends to multisite installations, although it is recommended to activate it on a per-site basis to comply with ads.txt specifications. Users should note that the plugin requires the website URL to be set at the root domain, as it will not function correctly in subfolder installations. Ads.txt Manager is a robust solution for publishers aiming to enhance their ad management processes.
