Is modifying the rel canonical in theme.liquid a viable solution to limit duplicate product pages?

Technical Q&A
1

I’m trying to limit the number of duplicate product pages and maintain functional breadcrumbs.

To keep the breadcrumbs, I’m using the collection page products. All of my internal links point to:

/collection/collection name/products/product name

I also added /products/* as disallow to robot.txt

Do I need to modify the rel canonical in theme.liquid from the default?

Default is:

{%- if canonical_url != blank -%}

{%- endif -%}

Would something like this work?

{% if template contains ‘collection’ %}

{% else %} {% endif %}

I’ve made these changes and everything seems to be working well. Let me know if what I’ve done is a viable solution or if I should go about this in another way?

Yeah, that didn’t work… just a little off… for any looking to get this done… this is the code I used and it is working.

{% if template contains ‘product’ %}

{% else %} {% endif %}
