Ensuring good-quality content involves vigilant monitoring of duplicates, which is crucial for maintaining site page indexing – akin to the ongoing effort of weeding.

What types of duplicates are we addressing?

  • Displaying identical product pages at diverse URLs.
  • Pages featuring closely similar content and products, often with nearly identical descriptions.
  • Versions of the same domain present duplicate challenges.

The creation of duplicates is related to the operation of the Shopify platform. The platform can create a single product page from multiple URLs with identical or nearly identical content. In some large stores, one product can be included in several collections (sometimes up to several dozen or even hundred if the store is enormous!). This means that its URL is generated for each collection in which the product resides.

Canonical tags are a good solution for you in the fight against duplicates.

Duplicate content poses a significant threat to SEO. When search engines encounter similar pages, ranking confusion may arise, potentially lowering the rank of all these pages.

Google leverages canonical data to evaluate page content and quality. Canonical pages undergo more frequent crawling compared to non-canonical counterparts.

However, the rel=”canonical” tag is merely a suggestion; its usage doesn’t mandate search robots to index the specified page exclusively. Google considers various factors, including internal/external links, protocol, Sitemap file inclusion, user domain, and page quality.

Canonical Tag and Canonical URL Definitions
