WordPress product page content is duplicated, how to write it to be more unique and not affect SEO?

It doesn't have to be completely different for each product, just have a point of differentiation. Remember 3 points is enough: title do not just change the model, add a different angle (use / style / scene); short description of each product only emphasize a different selling point; FAQ do not copy the whole paragraph, change 1-2 questions can be. Parameters, materials, after-sales repetition is not a problem. As long as the whole page is not copied, Google will not be penalized.
