There isn't a percentage, and Google doesn't count one document in total as being unique or not. http://spunwrite-blog.com/2007/07/0...e-do-your-spun-rewritten-articles-need-to-be/ Above is an interesting article on the concept. In my experience Google bases the "uniqueness" almost on individual sentances, and the page is rated for the total number of unique sentances on a page. This means you can have some dupe content, as long as you don't want to rank for any of the keywords in that paragraph.
Here is the stand of Google regarding duplicated content issue: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=66359
In fact, if you submit an article to 100 directories, and it is published on them all, you will get credit for 100 links to start with. That will then gradually decrease, theoretically to one after a few months, but if you submit one each week, you will receive more links than are lost, and gradually build up a good PageRank and Google listing irrespective of 'duplicate content'. Google likes content on Article directories, so appears to me to be taking a lenient view. This is all throrugh practice and what happens with me, and I submit many articles each week for clients that help them to achieve high listing positions
Stop wasting your time with duplicate contents if you target to SEO for Google. Instead, get 100% unique article that will actually help you in Google.
And diversify your link profile. Reach out to other webmasters with different objectives in your similar industry, partner up, and get rankings and PR fast. Kick up natural link evolution by writing GREAT high quality, very unique, and linkable content and get in front of your target market, wherever they are.
Extraordinary content is liked by Search Engines. To each site, only one of its kind articles should be submitted. Duplicate content issue can occur by copying articles.
for posting on your own site/blog, i suggest using 100% unique content. for publishing on 3rd party sites, article directories or web 2.0 sites for example, you will not get penalized for duplicate content as google cannot penalize your site for having duplicate content on 3rd party sites. however, try to make them as unique as possible for better result
Any secret like this would be extremely closely guarded at google. And as @creativedevelop said, Google measures uniqueness on a sentence by sentence basis. But to qualify for unique it would need to be 60-70% original in order to be unrecogisably new in my view.
Brad, I'm definitely agreeing with you here... I have noticed a particular website of yours climbing the SERPs for the same keywords that I'm targeting as well. Keep up the great work... Cuz its working.
Due primarily to the increase in popularity of affiliate programs, duplicate content on the web has become an increasingly significant problem for both search engines and search engine users alike with the same or similar sitesdominating the top positions in the search engine results pages. There are times when duplicate content is considered legitimate by both search engines and visitors and that is on resource sites
ha ha ha ha ha ha ha ha ha He got it from here: http://www.beanstalk-inc.com/tactics/grey-hat.htm Click the link and then scroll down to where it says "Duplicate Content" abrahimben46's post above is as good as duplicate content gets... Or pretending to know what they are talking about! Unless that's his site of course.... lmao!
I'd like to think that if your page passes a Copyscape for uniqueness then your chances of getting that page indexed by google is at least 75%
Making money on line is hard enough at the best of times, so I suppose the answer is, if in doubt don't duplicate.
Going with unique content is best in my opinion. if you get banned after some time, whatever effort you put is lost.
