How should we handle redundant tags for SEO in a Shopify 2 theme upgrade?

Technical Q&A

We’re supporting a Shopify 1 themed site whose original devs used utility tags for filtering. Now we’re re-theming and upgrading to a Shopify 2 theme taking advantage of storefront filtering and metafields.

We can convert all of the utility tags (e.g. Item_Value1, Item_Value2 where the underscore is used by 1 themes for filtered collection pages) to appropriate metafields.

The client was also once advised to add a tag for each product with the part number of their product for no other reason than “better seo”. They get huge search volumes for product numbers, but these are all in both the product title and description (and a tag!)

There are about 8000 products filtered by about 40 different utility tags.

From an SEO perspective, what are your thoughts about handling soon-to-be-redundant tags?

Is it safe/best to remove them?

Does Shopify create URLs using these tags?

Over the next 18 months we estimate a further 20,000 products being added, so would like to get this right.

Hi,

Does Shopify create URLs using these tags?

Yes,

Either you noindex the tag using meta robots or use canonical tag(use parent URL in all related tag) to avoid the duplicate content issue

Thanks. I’ve found the url paths for tags and looking at the html of a small selection, seems all have been canonicalised to the route product. So, seems all ok on that front. AlsoGoogle Search Console isn’t showing any of these indexed, another bonus.
