What is Duplicate Content in Magento 2?

“Duplicate content in Magento 2 refers to identical or very similar content appearing on multiple URLs within your store.”

It usually happens due to product variations, category structures, or URL parameters. Search engines often struggle to determine the most relevant version to index and rank.

Magento 2's complex architecture inadvertently generates duplicate content through various means, like:

• Different URL structures for the same product

• Multiple category paths to a single product

• Pagination and filtering options

• Session IDs in URLs

• Similar WWW and non-WWW versions of pages

• HTTP and HTTPS versions of the same content

Addressing all of these issues is necessary to maintain strong SEO performance.

Exploring Common Magento 2 Duplicate Content Causes

1. Product Variations

Product variations often lead to duplicate content. Each variation generates a unique URL. It creates multiple pages with similar content. Magento 2 allows configurable products. These can result in numerous URLs for the same item. Variations in color, size, or other attributes can cause this issue.

For example, a T-shirt available in different colors and sizes may have separate URLs for each combination. It results in duplicate content since the core product description stays the same across these URLs.

2. Category Structure

Complex category structures can cause duplication. Products may appear in multiple categories, resulting in different URLs for the same product. Magento 2's layered navigation can worsen this issue. It creates additional URL parameters for filters and sorting options.

Consider a product listed under both "Men's Clothing" and "Summer Collection." Each category generates a unique URL. It results in duplicate content for the same product.

3. URL Parameters

URL parameters can lead to duplicate content issues. These parameters often don’t change the core content. Search engines may see them as separate pages. Magento 2 uses parameters for sorting, filtering, and pagination. It can create multiple URLs for the same content.

For instance, a product page might have URLs with parameters for sorting by price or popularity. It results in duplicate pages with identical content.

4. Session IDs

Session IDs in URLs can cause duplication. Magento 2 may append these for tracking purposes. Each user session could generate a unique URL. It leads to duplicate content across different sessions.

5. WWW and Non-WWW Versions

Having both WWW and non-WWW versions of URLs accessible can create duplicates. Magento 2 allows both versions by default. It makes the same content available on two different URLs.

For example, both "www.example.com" and "example.com" might serve the same content. It leads to duplication.

6. HTTP and HTTPS Versions

Similar to the WWW issue, having both HTTP and HTTPS versions can cause duplication. Magento 2 supports HTTPS. However, improper configuration can leave both versions accessible. It creates duplicate content across different protocols.

An example is when both "http://example.com" and "https://example.com" are accessible. It results in duplicate content.
