When we refer to Duplicate Content (duplicate content) we mean a whole text or part of it, which can be read identically, or almost completely, within the same site or other. The practice of duplication of web content, can be done in good faith, or intentionally. Examples of Duplicate Content that are not considered deceptive, include forum discussions, which can generate several pages, printable content, different URLs for the same page, etc .... Some sites are willing to do it anything to affirm their brand or services. Many adopt the strategy of creating "harmful" duplicate content with the intent of deceiving search engines.
In this case, the final goal is only to obtain excellent and productive positioning results on the front pages of the engines. Unfortunately, this system, besides being unethical professionally, is bound to fail. In addition to failing to produce anything good, it can prove to be a problem with heavy consequences. The duplicate site, besides producing a negative influence to indexing on search engines, it also has possible legal consequences including being permanently removed. Undoubtedly search engines prefer to "reward" sites with original and unique content, and not that are a copy of another. Contrarily, when a search engine detects multiple identical pages, it selects them through a filter, and decides to show only one page.
Usually the page that has the best trust is chosen, considering basic elements such as: page age, site authority, number of incoming links, pagerank, etc. To avoid the problems that Duplicate Count can generate, we recommend writing high quality content for the web. Doing a good job of optimisation following specific guidelines and simple SEO rules, is fundamental. Content rich in originality and personalisation acquires more and more value. Authenticity becomes an important factor that earns the author more credibility and allows the site to differentiate itself from the others.
