Kristina Azarenko discusses common issues with eCommerce product pages and provides solutions. The three main issues are: 1) Almost identical products found on different URLs (e.g. different colors), 2) The same product found in different categories with different URLs, and 3) Products with the original manufacturer's description. Solutions include creating a single URL for all product variations, removing category indications from URLs, choosing a canonical product version, and adding unique content like customer reviews, questions and answers to differentiate products.
