Product variants: separate URLs with cross-canonicals, or one page?

'Q: Red, blue, green of the same shirt — separate pages canonicalized to one, or a single page with a color picker?'

Short answer: One page with an on-page variant selector by default; separate self-canonical URLs only when colors have real, distinct search demand.

The longer version: A single consolidated page concentrates all links and reviews on one strong URL — usually the right call. Splitting into /shirt-red, /shirt-blue and canonicalizing them all to /shirt just creates dead pages Google may ignore and dilutes nothing useful.

But if 'red prom dress' has its own meaningful search volume, a dedicated indexable /red-prom-dress page (self-canonical, unique title and copy) can rank for that intent — splitting is justified by demand, not by inventory.

Example: 8 generic phone-case colors = one page, variant swatches. 'Black leather sofa' vs 'grey leather sofa' both with thousands of searches = two indexable pages.

Rule of thumb: Consolidate unless the variant is a query people actually type.
