Welcome to the Q&A Forum

I do have duplucate content (products) on my new platform and I wonder if putting all the links of those products on Canonical could benefit the original specialized websites. Google has not said exactly how they treat these. I believe that rel=canonical has become a substitute for the old method of building links by article syndication.  I believe that many people are doing it at industrial scale and that google will eventually start to discount the beneifits, ignore the benefits or penalize some uses of rel=canonical. For that reason I am staying away from rel=canonical just like I stay away from dropping links in forums, buying links, linkwheels, syndicating articles, etc.  That's me being cautions and taking care of my websites. Each person must decide what they are willing to do.  You can wait until Google publishes it in their webmaster guidelines or you can stop doing something that Google might simply refer to as "manipulation" without getting specific about it.  Google is specific about very few things.

Hi there, Just to confirm, you did implement AMP Analytics with these pages, correct? Are you measuring both AMP and non-AMP traffic in the same property? If so, this should show up as referral traffic (look for the source 'cdn.ampproject.org'). I recommend reviewing these resources below to make sure you are properly tracking and attributing AMP traffic, hope these help! - What's Your AMP Traffic Really Doing? Set Up Reporting in 10 Minutes "Due to various technical restrictions, AMP traffic uses different Client IDs from those for web traffic by default. AMP pages also load faster and show different traffic patterns thus resulting in different metrics. Using a separate property to measure AMP traffic allows for better analysis of metrics and a more accurate picture of your traffic. If you use a single property to measure both AMP and non-AMP traffic, use the data source dimension or a custom dimension to distinguish them. By default, Google Analytics will send the value "AMP" within the data source dimension, which is the value you can use to segment/filter or otherwise analyze AMP vs non-AMP content within a single View. To configure a custom dimension, see Extending googleanalytics. In addition, you can use the AMP Client ID integration to use a single Client ID for a user across AMP and non-AMP traffic."

Yup, will work if you share it in the right places. We have several articles on our blog which got a lot of backlinks after we shared the link on Quora, reddit, inbound, growthhackers. Bloggers picked up on these and linked to them in relevant articles.

Hi manoman88, Sounds like you know what you're doing and the short answer is yes, what you have outlined above is the perfect use for hreflang tags despite there being slight variations in the product available to these different countries. Cheers, David
