Thanks,

Hello,

Duplicate content is a key factor in SEO, if Google thinks that your content si a copy from another site, the page copied will be penalised by the Panda algorithm.

If someone copies your content and is indexed earlier than you, then, your page will rank lower than your thief.

To prevent that, you must share the content immediately on Google Plus, and other SocialMedia and social bookmarks.

If Google thinks that all of your content is a copy, not only a page, but your entire site could suffer a penalty, or even a un-indexation.

if you think that your articles are being stolen or that you bought articles and the redactor is giving you copies from somewhere, you can chek that with copyscape.com

I hope to be usefull and easy to understand!

Hi,

I will have to disagree with Natan - duplicate content is not really such a big deal as a lot of people are advertising it for.

There is no such thing as duplicate content penalty and de-indexation of a site based on duplicate content - it was never the case and it will never be the case.

I am not saying you don't have to deal with it - you do - you should - but only when appropriate.

As far as Panda is concerned, it is a ranking or you can even call it a filter - but not a penalty and it is only based on market and competition. Yes, with low authority and a strong competition providing more or less the same information you can get under this Panda filter but it's way more then that - it's not 1 and 0 - black and white with it.

To see how "unique" your content is and where on the web other sites holds the same or parts of your content you can use copyscape - as Natan mention - but for the rest, sorry Nate, the advice is just not right.

Cheers.

Sorry to disagree with you: if "copied" content was a problem, then we will have sites like Techmeme out of the index.

The problem with with publishing syndicated content is not the act of republishing it, but the value you add or not while republishing the content of another site. For instance, if you add classic content curation practice, as commenting inline or before or after the "copied" content, or if you published it and open a discussion that generates UGC content, then that copied content is not a problem.

Be aware, I am talking of content republished with the permission of the original author/publisher of the content itself.

Other thing is scraped content, which don't add value. In that case the scrapers seriously are at risk of Panda or, simply, of being filtered out of the visible index.

Similarly duplicated content can be a risk when it comes to products description in an eCommerce or Classified site. That content - again - seriously can lead you to a Panda penalization. That's why it is always better to rewrite the standard products description, or add more unique content that may add value, as "the site review" of the product, users' reviews, etc etc.

If you want to check who "copied" your content you can use - as told by the others - Copyscape.

Or, you can use Google itself.

Pro Tip:

• set search in order to show you 100 search result per time;
• tell Google to show you also the results it may have filtered out for being "substantially identical" to the ones it is showing you already;
• use the scraper extension for Chrome and scrape the Google results and export them in Google Docs, so to start analyzing the site that are scraping your content
• if the content you write is copyrighted, you can ask Google to deindex the site scraping it in order to defend your rights as the original Author.
