Change to make in theme.liquid
It adds a canonical tag for tag-filtered pages, back to the base collection/blog page.


*** Find this is the standard canonical tag code: ***

<link rel="canonical" href="{{ canonical_url }}" />


*** Completely replace it with this: ***

{% if template contains 'collection' and current_tags %}<meta name="robots" content="noindex" /> <link rel="canonical" href="{{ shop.url }}{{ collection.url }}" />
{% elsif template contains 'blog' and current_tags %}<meta name="robots" content="noindex" /> <link rel="canonical" href="{{ shop.url }}{{ blog.url }}" />
{% else %}<link rel="canonical" href="{{ canonical_url }}" /> {% endif %}
