The custom domain or branding comes along with a dynamic shareable report. It's a way you can have your own branding. For example, instead of the TopicMojo logo at the top of a report, it will be replaced with your company logo.
The custom domain also refers to the URL of your company's website. For instance, our current default URL for TopicMojo reports is "www.topicmojo.com." But you can have a custom one if you want to. Which would be something like "www.yourdomainnamehere.com."
The custom domain feature is on our roadmap and it will be live down the map. We need you to vote it so we can understand the user demand and release it accordingly.
