"Indirect ROI" is agency-speak for "we can't measure this, but trust us." The problem isn't that people quit too early-it's that they mistake vanity metrics (followers, likes, comments) for pipeline.
If you've got 50k followers and can't point to a single closed deal or referral that came from LinkedIn, you're not building a brand, you're building an expensive hobby. Indirect ROI sounds nice, but in e‑com you either move units or you don't.
