What does duplicate content mean and how can it be prevented?
Duplicate content refers to the publication of identical or very similar content under different URLs. This is a widespread problem that can significantly affect the SEO performance of a website.
Why is duplicate content a problem?
Search engines such as Google strive to provide users with the best possible and most relevant information. The presence of duplicate content works against this, as the search results displayed would all be the same, which is not particularly user-friendly. Therefore, unique and high quality content is a key factor for Google's algorithm when evaluating the quality of a website.
How the SEO agency helps to protect your rankings
Duplicate content can occur when identical content is present on several websites. This can lead to search engines downgrading the pages or even removing them from the index. To prevent this, SEO agencies offer specialized services to protect your website from the negative effects of duplicate content.
Internal duplicate content
Internal duplicate content can occur when identical content is present on different pages of the same website. This should be avoided in order to achieve a good search engine ranking. It is important to have a clear structure and unique content on each page of your website.
Duplicate content in e-commerce
E-commerce websites are particularly susceptible to duplicate content as similar products often have similar descriptions and images. However, it is important to avoid this in order to maintain SEO ranking. Unique product descriptions and customer reviews can help with this.
How to discover duplicate content on third-party websites
It is important to detect duplicate content on external websites, as it can potentially be harmful to your SEO ranking. Tools like Copyscape can help to identify such content and take appropriate measures.
How to deal with duplicate content
There are various ways to deal with duplicate content, such as removing pages with identical content or using canonical tags to indicate to search engines which page is the original source. This helps to maintain the integrity of your website and achieve a better ranking.
How to deal with duplicate content when using multiple languages
Duplicate content on multilingual websites can be harder to avoid, but there are strategies such as using rel=“alternate“ hreflang tags to show search engines that each language is a separate page with unique content. This promotes a global SEO strategy and improves the user experience for people from different countries. For WordPress, for example, WPML would be one of the first places to start.
How is duplicate content created?
Duplicate content can arise in various ways, both internally and externally. Internal, repetitive content can occur when your own site is accessible via multiple URLs, e.g. through different domain names or protocols. External duplicate content is the result of the same content on multiple domains, which can be caused by the distribution of press releases or content scraping.

Content is king and an important ranking factor for search engines
Although duplicate content is generally considered negative, there are cases where it may be necessary, such as legal information or the repetition of some content elements in e-commerce stores with similar structures. In these cases, Google classifies it as necessary and does not automatically penalize it.
How can you avoid duplicate content?

There are different approaches to solving this problem, and each requires a specific measure. Our team at Apalion AG will develop and implement the right solution for your specific challenges.
