Anti-pattern — single hard percentage or dollar figure

Summary

Anti-pattern: "You should spend $14,750 on your website" / "Your digital maturity is 47%" / "You need 8.2% of revenue on marketing."

Why it fails: False precision the data does not support (sister brief Research brief: SMB widget spend benchmarks — feasibility of a "digital-minus-ads" % of revenue (June 2026)); becomes a liability the moment reality diverges (Pena-Marin et al. 2019 — precise estimates BACKFIRE when shown wrong).

Replace with: A tier + a range with confidence flag.
