Does associating the same question with different products create duplicate content?

Associating a useful question with several products does not, by itself, trigger an automatic penalty. Google states that some duplication is normal and does not violate its spam policies.

There is no universal threshold of “one, two or three questions” guaranteeing no effect on search visibility. When pages are identical or very similar, Google may select a canonical URL and show only one version in search results.

Reuse shared answers when they genuinely answer the customer’s question, and keep descriptions and information specific to each product.

See Google’s canonicalization documentation.
