Working on a large scale eCommerce site (15,000+ products), with separate URLs for Mobile & Desktop.
On desktop product pages, we have canonicals set up for color variations, so /product/green/, /product/red/, /product/blue/ are all canonicalized to /product/white/.
At the same time, we have rel=alternate on every desktop page to indicate the mobile version.
My question is, how should I handle mobile canonicals for color variations (canonicalized on desktop)? Does the following example scenario represent a problem for indexation?
On desktop (https://www.example.com/product/blue/)
<link rel="canonical" href="https://www.example.com/product/white/" /><link rel="alternate" media="only screen and (max-width: 640px)" href="https://www.example.com/mobile/product/blue/" />
On mobile (https://www.example.com/mobile/product/blue/)
<link rel="canonical" href="https://www.example.com/product/blue/" />
Is it a problem that the mobile URL is canonicalized to a URL that is not a true canonical? Should it point to https://www.example.com/product/white/ instead?
Responsive website coming soon, but until then...stuck with these 2 sites
<link>tag does not use and does not need a closing slash and never has in HTML. – Rob Jan 14 '20 at 22:47
