The major search engines are constantly trying to improve the quality of their search engine results in an effort to provide the best quality content for users. When duplicate content is indexed by search engine spiders, valuable time and processing power is wasted. As a result, search engines have blocked sites that used duplicate content from their database, ultimately favouring the site that either had the content first, or I believe, the one site that has the greater online history.



In addition, the major search engines have a bad taste after dealing with so much duplicate content created by spammers over the past several years. As a result, posting a duplicate website is an offense that can quite literally blacklist a domain; there are few things the search engine properties dislike more than being gamed by spammers.

Deleting the site is the only option unless you want to create an entire new website with unique content and a unique purpose. That said, by deleting the website you can still ensure the effort you put into promoting the old site does not go to waste by pointing the domain to your new website’s domain using a 301 redirect. A 301 is a term used to describe a server protocol which Google and other search engines will ‘see’ when they visit the old site. The protocol essentially says that your content from the old site can be found on the new site and that this is a permanent forwarding of all traffic. 301 redirects are by far the best way to minimize your losses from shutting down a website that just might have traffic or inbound links.

It is very important that you keep the website that has the most backlinks and has been online the longest. Switching a website to a new domain is a dangerous step. This is because of Google’s famed ‘sandbox’. The ‘sandbox’ is really only an overused turn of phrase that represents a portion of the Google algorithm which considers the age of the domain as a signifier of trust. Generally, new websites will require 6 months to a year before substantial rankings are evident; this is kind of a right of passage that Google appears to be enforcing on the average website. Sites that are obviously popular and quickly gain a load of legitimate link popularity will easily avoid the sandbox (because Google can not afford to miss a ‘great’ website) but this is not the common scenario.

How to avoid Duplicacy:

In most cases the amount of duplicate content used within a template in a content management system (CMS) is negligible. If, however, you have a large number of pages created using a page where 90% of the text is duplicated and only 10% is unique you do have a reason to make some changes. In my opinion it is crucial that every page within a website be composed mostly of unique content with the exception of catalogues and shopping carts where text simply has to be reused over and over.
