Roundup page vs single-product review: 3.4x EPC gap

Roundup page vs single-product review: 3.4x EPC gap
Same niche, same traffic source, n=21,000 sessions:
— Single-product deep review: EPC $0.13, ranks for one buyer-intent keyword
— "Best [category] for [use case]" roundup: EPC $0.44, ranks for the whole comparison cluster
Roundups win because the visitor is mid-decision and you offer the choice — every product is a valid exit. Single reviews catch buyers who already chose, a smaller pool.
Tradeoff: roundups need 5-8 products kept in stock and priced live; single reviews are lighter to maintain.
So what: lead with roundups for discovery traffic, support with single reviews as internal links for the buyers who drill down. Don't build single reviews as your top-of-funnel.
