Penalties For Duplicate Content Issues
A phenomenal truth for ranking good in the SE’s is feeding them with unique and quality content. Search Engines are always in search of good content related to your business or domain. “Content is the King” has been a well known proverbial phrase in the SEO community.
Search Engines dislike duplicated content and penalize them mainly due to two reasons: First, they don’t want to show the same pages in their search results. And secondly, they don’t want to spend the resources in indexing pages that are substantially similar.
Duplicate Content : Chances of making the mistake
i) Multiple Domains Supplying Same Content :: Resolve by a permanent 301 redirect to the best suited domain.
ii) Site Redesign :: A change in URL architecture (URL structure change — converting .html to .asp or .php etc.) :: Repair by a permanent 301 redirect or drop the old versions by setting a proper 404.
iii) CMS sites (e-Commerce and PPC campaign sites) — Result in same product pages with different dynamic URL’s :: Repair by a permanent 301 redirect or using the robots exclusion protocol.
iv) Landing pages having same content — Dynamically generated landing pages resulting in Dupe Content :: Resolve by a permanent 301 redirect or using the robots exclusion protocol.
v) Content syndication and scraping spam issues result in dupe content penalty.
