Pick the category in the Publish box and the author in the Campaign Options box of the campaign editor.
- Categories: tick one or more boxes. The list shows all categories on your site. AI AutoPost never creates categories, so create them first under Posts → Categories. If you tick nothing, WordPress uses its default category (usually Uncategorized), and the SEO check flags this.
- Post Author: choose an administrator, editor or author. New campaigns use your own user. Imported posts are published under this user, also when the campaign runs on its schedule.
Tip: tick one category per campaign and make a separate campaign for each category, with feeds about that topic. This keeps your category pages clean, and it is exactly how Auto Setup builds its campaigns.
