Add the Conditional Canonical URL to theme.liquid

The collection templates need to have the canonical url indicating duplicate content to search engines. Failing to do this step might have negative SEO implications for the web shop and is not recommended.

Replace this default canonical tag from Shopify: 

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

With the conditional function to add the canonical URL to Nosto generated category pages: 

{% if product == blank and collection and collection.metafields.nosto != blank %}
  <link rel="canonical" href="{{shop.url}}/collections/{{collection.metafields.nosto.sourceHandle}}">
{% else %}
  <link rel="canonical" href="{{ canonical_url }}">
{% endif %}

Adding a conditional function to filter out Nosto collections

Default Shopify stores for example rely on templates/list-collections.liquid to create box-style category listing used for example on the main collection page. When using similar kinds of functions that will loop out all collections, the Nosto generated clone collections need to be filtered out from the template. 

Replace this default list-collections function: 

  <div class="grid grid--uniform">
    {% for collection in collections %}
        <div class="grid__item small--one-half medium-up--one-third">
          {% include 'collection-grid-item' %}
        </div>
    {% endfor %}
  </div>

With exactly the same function, excluding collections with the Nosto metafield applied:

  <div class="grid grid--uniform">
    {% for collection in collections %}

      {% if collection.metafields.nosto == blank %}
        <div class="grid__item small--one-half medium-up--one-third">
          {% include 'collection-grid-item' %}
        </div>
      {% endif %}  
 
    {% endfor %}
  </div>

Adding a conditional function to use original collection image. 

In some cases an online store might rely on the collection image for prominent styling items such as the hero banner image, or in metafields such as og:img for example.

In these cases you need to add a conditional that leverages the original collection image instead of the temporary image added by Nosto to differentiate clone collections within the shopify admin.

{% if product == blank and collection and collection.metafields.nosto != blank %}
  {{collections[collection.metafields.nosto.sourceHandle].image.src}}
{% else %}
  {{collection.image.src}}
{% endif %}
