Duplicate Web Site Contents Penalty Issue

The "SEO/Search Engine related - Duplicate contents penalty" issue is one of the biggest issues that we are dealing everyday with SEO task and update the websites. The issue is that search engines such as Google, Yahoo etc., will penalise or banned a site if much of its content is also on other websites.

There is a real duplicate contents penalty for content that is duplicated with minor or no variation across the pages of a single site. There is also a "mirror" penalty for a site that is more or less substantially duplicating another single site. What we're talking about here is the reprint of pages of content individually. The punishment can mean making it less likely that the site will appear in search results. Punishment can also mean removal from the search engine's index of web pages.

Google penalizes page rank when it determines that content is duplicated by other sites.
