The Odoo website_sale module by default shows the first product_variant on the product page.

That has a http://schema.org/Product scope that gets crawled by googlebot and the products get recognized as products. 

But as changing to another variant happens through javascript and the crawler bots do not do that. Those other variants never get crawled, and thus never get into the google products database.

That is pretty sad SEO wise ... for a webshop.

Anyone found a solution for this?
