View mode pages use the parent entity canonical URL, so they are considered duplicate content by search engines

@chucksimply - I can see in the browser's "view source" that the the duplicate canonical url is still there as mentioned above in the lawnmower example.

I use Context Metadata → together with this patch → .

Thanks @runzipel. I ended up switching away from View Mode Page to using a Views page displaying "content" format with a specific view mode. Don't have to worry about this current issue now, and have more control over the meta data.
