We have a very busy website which primary domain is news related. In addition to our website, we have a couple of subprojects, which are not news related, but are hosted on the same domain with subfolder structure. Reason for this, is because all projects under the same brand, and management prefers subfolders over subdomain.
Due to possible brand changes, we tend to migrate one of our projects to a separate domain, but we are not sure what will that do to our SEO, not just for that subproject, but for our main domain in general. What are possible downsides and upsides of this migration?
Will the value of our domain decrease, because we will lose approx 30 million page views in our primary domain per month because of the migration.
