Canonical product URLs [17th Mar 2020]
We’ve recently introduced a change to the code used in our Shop websites.
Now, if a product appears in multiple categories, the shop will output a rel=“canonical” meta tag that points to the shortest URL for that product.
This tells search engines that there are multiple URLs for the same page, and points them to the ‘preferred’ link so they know exactly which version to display in search results. This will give a minor boost to a site’s ranking, as the value of any backlinks to that page will no longer be divided between several URLs.
