You have work that's manual, repetitive, and high-volume
The clearest sign. One client had 3,161 product pages that each needed a unique, on-brand SEO title and description, weeks of manual work nobody had time to do. Another had grant applications that ran 6 to 40 hours each. When a task is high-volume and follows a pattern, it's a good fit for automation, and you feel the pain every week.
