So I'm setting up hreflang tags on an ecommerce site. The sites are in the USA, Canada, etc... . The Canadian site will have fewer products than the American site, meaning that there won't be as many pages in each category as there are on the American site. What is the correct way to handle hreflang tags on these extra category pages?
To put this another way, the American site may have a category with 3 pages of products, while the Canadian equivalent only has 2 pages of products. What happens to this extra American category page? Should it get an hreflang tag linking to the first page of the equivalent Canadian category? Should it not get any hreflang tags because it has no true Canadian counterpart?
Does it matter at all if it has a canonical tag pointing to the first page in the series anyway?
