Our banner Ads are distributed amongst all of the Dread Network's platforms and require approval over on Dread where you can then access a variety of promotion tools within the platform including the Banner Ad service. For more information please contact us via the /d/Dread Modmail, you can find a working link for Dread here.
As for getting your service listed within the directory, it isn't the most straight forward process and will be mostly reserved for useful and trusted services that have established themselves over some time. This process will be different for every service, especially depending on the category of your site.
