The World Wide Web is a race for Supremacy. No doors are given to weaklings for only the fittest will survive.

Supremacy means dominance in every aspect. Moreover, reliability, functionality and originality must be yielded in order to rule the web. Another thing that a site owner or web master must do is to avoid duplicate content as well as its penalties.

Search engines are equipped with secret weapons to shun sham and deception. An example of which are filters. Filters remove duplicate content from the pages that search engines are indexing. Moreover, duplication of content is also penalized by poor rankings. Filters also detect original content. Further, websites with such content is given rewarding rankings.

Webmasters and owners must also be aware of the functions of filters so as not to sacrifice the website in case of misdemeanors. Filters are sensitive to 'doorway pages', 'scraped content' and identical core material authored by different individuals.
