The ideas shared on the internet are countless, therefore it is not wrong or “unusual” for websites to have similar pages. However, duplicate content is a big problem in Google’s scoring system.
When seeing the action of manipulating search engine rankings or increasing traffic, Google may deduct the content from your website.
Several documents in Google’s “Advanced SEO” section clearly state that your website creates a poor user experience when you use duplicate content. Your web should not lead visitors to only see the same thing over and over again in a series of search results.
“Google tries hard to index and show pages with distinct information. This filtering means, for instance, that if your website has a “regular” and “printer” version of each article, and neither of these is blocked with a no-index tag, we’ll choose one of them to list. In the rare cases in which Google perceives that duplicate content may be shown with intent to manipulate our rankings and deceive our users, we’ll also make appropriate adjustments in the indexing and ranking of the websites involved. As a result, the ranking of the website may suffer, or the website might be removed entirely from the Google index, in which case it will no longer appear in search results.” – View the original source: here.
How does search engine identify duplicate content?
Duplicate content is split up into 4 types by filters of popular search engines (Yahoo, MSN, Google) as follows:
- Duplicate pages: are scraped content to make the website’s content look different. Currently, search engines have to deal with this dilemma. “Blog” are becoming the most plagiarism source of content because they are so popular.
- Duplicate pages 100%: are similar pages or completely identical to another website on the internet – also known as spam. For example, a product website with the same design contained similar content will most likely be considered a duplicate by the filter. Another example is a website with doorway pages. Almost doorway pages are created for spamming search engines to dominate search engine results.
- Duplicate e-commerce pages: many e-commerce sites use the manufacturer’s product description, even hundreds or thousands of stores in the same market segment use the same product description. This repetitive content is harder to detect but is still considered spam.
- Copy articles: do you think that when a newspaper or website across the internet republishes your article, you should get good reviews? Your articles will be complicatedly filtered by search engines. Yahoo and MSN identify the source of the original article, then rank the most relevant link. Google, on the other hand, does not think the article should rank well.
So, how does the copied content filter work? When crawling a website, search engine robots read the pages and store information in a database. Next, compare the new findings with the information available in this database. Depending on the overall website review factors, the robot will identify what is duplicate content and screen the website for full spam elements. If it is true that your website has duplicate content with other websites even though it is not spam – it can still be considered spam.

Duplicating content will make the task of content writers as well as web masters difficult than before. Many websites have been affected by their content being copied and spammed on search engines.
