Welcome to the Q&A Forum

I would recommend to have structured data for each individual listing. Try to structure as much information as possible and this should help the search engine and your SEO.

You're right! To add on to Gaston's response, the nice thing about the rel=canonical tag is the fact that it passes on the same amount of link juice that a 301 redirect does, and it's a lot easier to do (that fact that these links are supported by Google, Yahoo, Bing, and other top search engines doesn't hurt, either). Just always keep in mind that rel=canonical pages won't appear in search results!

Thank you so much for your feedback.
