I am wondering how you would choose which page to use as a canonical ?
All our articles sit in an article section and they are called in the url when linked from a particular category. Since some articles are in many categories, we may have several links for the same page.
My first idea was to put the one in the article category as the canonical, but I wonder if Google will lose the context of the page for it's ranking because it will not be in the proper category.
For exemple, this page in the article section : http://www.bdc.ca/en/advice_centre/articles/Pages/exporting_entering.aspx
Same page in the Expand Your Sales > Going Global section :
http://www.bdc.ca/EN/advice_centre/expand_your_sales/going_global_or_international_markets/Pages/RelatedArticles.aspx?PATH=/EN/advice_centre/articles/Pages/exporting_entering.aspx
The second one has much more context related to it, like the breadcrumb is showing the path and the left menu is open at the right place.
For this example, I would choose te second one, but some articles may be found in 2 or 3 categories.
If you could share your lights on this it would be very appreciated !
Thanks
