Amazon could segment its performance by opening retail stores (by opening shops in every city apart from confining to e-commerce operations), engaging in crypto-paying opportunities (can provide crypto-payment options while maintaining other currency options), and expansion of the sale of digital products applicable on an international basis.

Procter & Gamble could segment its performance by product category (e.g., beauty and grooming, household care, and health and well-being), product line (e.g., Crest, Tide, and Bounty), and stock keeping units (e.g., Crest Cavity Protection toothpaste, Crest Extra Whitening toothpaste, and Crest Sensitivity toothpaste).
