First, what is a duplicate? Let’s start our article by answering the question. Duplicate means copying. Duplicate content means repeating or repetitive content. You should definitely, but certainly avoid such content. Generally, people who start a site for the first time think that they are expanding their site by preparing copy content. However, because many sites prepare content in this way will lead to the future.
Copy Content Problem in E-Commerce
One of the most common problems e-commerce sites experience is copy content. Quality, original and user-generated content without considering the content of e-commerce sites, SEO performance is very far back. Content copied from other sites or competing sites is actually one of the most damaging issues to your e-commerce site. Copying content from another site directly reduces your page value.
This is because you are using copy content. As soon as Google bots crawl your site, they will begin to directly lower your score as they encounter Duplicate Content. Another disadvantage of copy content to your e-commerce site is that the things that exist on your site exist on other sites as well. You should know that if you try to simulate rather than differentiate from your competitors, you will go backward.
Why Duplicate Content Harm a Site?
The reasons why Duplicate content damages the site are:
Copy content affects your browsing budget and reduces performance,
It pulls information from pages in the Google index and tries to highlight the most relevant pages related to search results. If the content you have prepared is copied, it does not.
It will damage your connection profile. Always having a web profile with unique content and quality links will ensure that you are the only one in SERP and that you don’t have duplicate content.
Nine potential reasons for duplicate content are here, along with solutions to help you overcome them.
- Duplicate content due to redirected navigation
This problem is very common for e-commerce sites, and for SEO, this can be the worst of the list. On some retail websites, a single category page may have over 100 variations of the URL due to the many combinations of parameters for the face/ filter.
- Duplicate content due to product order
Similar to redirected navigation, index ranking parameters create duplicate variations (with the same content and meta content) of pages that are accessible to search engines. We recommend adopting methods to resolve the same problem as duplicate content caused by redirection by using meta-robot rules (recommended as the best option), the standard tag, or the use of parameters in Google Webmaster Tools.
- Duplicate content caused by hierarchical URLs
A few years ago, hierarchical URLs were considered the best practice for e-commerce websites because they show the structure of the website. Now, as SEO evolves, although hierarchical URLs often fall into the same category, duplicate content issues may be the cause of duplicate content issues because they create multiple variations of the same products. In most cases, these products will have the same or very similar content, which will be detrimental to search engine rankings.
- Duplicate content from search pages
Like redirected navigation, catalog search pages are another example of a common multiplier content perpetrator, and many of the large and small vendors can leave them available to search engines. Vendors have seen scenarios where they have more than 100,000 search pages indexed. This caused major problems with their rankings. The easiest way to prevent search engines from accessing these pages is to block the directory in the robots.txt file.
- Duplicate content caused by internationalization
Something we see over and over again at the dealers; before their entire content is translated, it is the introduction of international versions of websites. The result is duplicate versions of products and categories that contain very few different URLs. This is not always the case; some platforms will not manage international products with multi-site, so this problem will be less likely. In our opinion, the only really effective way to resolve this is to include international content, although you may temporarily block access to pages until all content is added.
- Duplicate content caused by pagination
Pagination was another common recurring content issue for online vendors and was seen as a major problem for SEO before the introduction of rel = next and prev tags. The rel = next and prev tags introduced by Google in 2011 allowed webmasters to tell search engines to prevent pages from being ranked and viewed as duplicate content.
- Duplicate content generated by session IDs
Session IDs are one of the most annoying things likely to occur in SEO, based on user sessions and causing an unlimited number of new recurring pages to be created/indexed. Ecommerce websites typically have problems with session IDs, because when there is a change in the hostname, unique IDs are added to the URLs so that the session ID is added to the next page visited. Eliminating session IDs can be a complete nightmare, but the best (and only real solution) is to solve the problem correctly and to prevent the creation of session IDs.
- Copied content from print pages
Often, on older e-commerce websites, there is an option on product pages to display a printer-friendly version of pages that have the same content but will appear in a different URL. These pages are duplicate versions of product pages and therefore duplicate content. To prevent these pages from being indexed, you must apply metadata rules (no-index, follow) to dynamic robots or if they do not allow the directory in the robots.txt file.
- Duplicate content from review pages
Customer reviews are displayed in different ways, depending on the way the site was created (or the platform built on it). Some websites display all reviews on product pages, and then only review different (usually ranked) pages. Here’s an example: As you can see, review pages have the same customer review content but contain a different URL. To prevent these pages from being indexed, you must either allow the directory in the robots.txt file or follow the meta robot rules if you are dynamic (no-index, follow).
