Can Duplicate Content Influence Rankings?
Search Engine Optimization Apr 05, 2006

Do search engines penalize duplicate content?
Duplicate Content Influences Your Rankings – Duplicate content can occur if web pages publish the same articles, if different domains point to the same web space, or if web admins steal content from other pages. If two shops sell the same item and use similar shopping systems, some product pages can also appear duplicate on the web.
Is there really a penalty for duplicate content?
There are many opinions in the discussion forums, but there is no proof that search engines really penalize duplicate content.
If there were a duplicate content filter, many news websites that publish AP or Reuters news would likely be banned from search engines. For example, you can find many web pages with the same article here. All pages can be found on Google. However, many people insist that duplicate content filters exist.
Why do people think that there’s a duplicate content penalty?
Not all web pages with duplicate content have the same search engine rankings. If a website is older, has more inbound links, and has more content, it is likely to rank better than a page that lists the same article.
That doesn’t mean that the website with the worst ranking has been penalized. It just means that the other website probably has more links, which are more important to search engines.
Some people think that there must be a duplicate content filter because additional domain names that point to the same web space as the primary domain name are usually not listed on search engines.
This is not due to a duplicate content filter. It’s an issue with canonical URLs. Google has addressed that problem with its latest update to the ranking algorithm.
Whether there is a duplicate content penalty or not has yet to be proved. To outperform your competition on search engines, ensure that your website has unique content that cannot be found on other sites.
If your website has unique content, you don’t have to worry about potential duplicate content penalties. Optimize that content for search engines and ensure that your website has good inbound links.
It’s hard to beat a website with excellent, optimized content and many good inbound links.
