Identifiers help systems determine which exact product is offered and reduce incorrect matching between similar items.
What you should know
GTIN is useful when a valid global identifier exists.
MPN, SKU and brand add identity and variant context.
Where ecommerce stores go wrong
Stores sometimes reuse one SKU across variants or put internal codes in GTIN fields.
Missing brand also weakens matching.
What you can improve
Use genuine identifiers, keep them variant-specific when appropriate and keep values consistent across pages, structured data and feeds.
