Before it writes
You set the rules for each site.
A brief for each site
Audience, language, seed keywords and image style are set site by site, so a recipe blog and a software blog don't read alike.
Your days, your hours
Pick publishing days and times, block out holidays, and keep days for articles you write yourself. Automation leaves those alone.
A budget for each site
Set what each site may spend on research, writing and images every month, and get an alert before it runs out.
